Blued metal in home spirits. The black knife of citric acid What does black metal give you?

To give it a presentable appearance, I would like to protect it from black metal. In home minds, this procedure is easy to complete, as long as you know the basic ways to do it.

House cleaning is a useful procedure that allows you to protect the family budget. In this case, a special coating is applied to the metal, which allows the fermentation to disappear and the drying liquid to be created.

The steel base is cleaned and degreased, then the surface is treated in the same way.

Safety rules:

• The entire robot wears mittens;
• It is important to mix different chemicals, so keep them in the original packages, beware of the speech ducts;
• Entrust the culprit with the funds from the guards, so that I can give you further help at any time;
• Work should be carried out in an area that is well ventilated;
• It’s better not to use metal utensils during work hours.

You will also need an emery paper. Use vicor to clean the surface. Degrease metal using acetone, perchlorethylene, B-70 gasoline and other organic compounds. The surface of this word is inert (unacceptable).

Metal cutting methods

Blackened metal is produced in the following ways: tin, acid and thermal. Such work can be carried out on juice, gold and other metal plants.

Luzhne blued

The most popular method of ferrous steel is chemical oxidation. The results should be clear and stable if the technology is carefully adjusted. The method is to prime the metal until it oxidizes. The work is cured at 135-150 degrees, the sauce is cooked until it has a characteristic smell.

Chernennya in a better way to carry out the pose with an apartment. It is possible to work in the courtyard or garage, in an area with fire ventilation.

So let's see. We first need to degrease and thoroughly clean the surface of the metal object. Remember that crow in household minds is impossible without preparing a meadow warehouse.

You can do this like this:

1. For porcelain containers, you need to pour 100 ml of fresh water into the container.
2. Add 100 g of technical soda and 30 g of sodium nitrate.
3. It is advisable to warm up and heat the warehouse to 135-150 degrees.

The preparations are ready, now you need to lower the vib that you plan to open. Then the metal is washed with distilled water, dried and evenly coated with machine oil.

As a result of the meadow raven, a bright black color with a blue tint may appear in the household mind. To remove the waste oxide melt, increase the amount of water in the mixture.

Acid crow

Before vaporizing, thoroughly clean the stain with an emery paper. Then you can defat it by soaking it in 10-20 minutes of gas or sodium triphosphate. After this the part is dried, and at that time you can prepare the cuts for the blacksmith.

Prepare like this:

1. Add 2 g of tartaric and tannic acid to 1 liter of water.
2. The ingredients are carefully combined.
3. The room heats up to 140-150 degrees.

In a heated warehouse, lower the part for 14-17 minutes, then rinse it with plain or boiling water (for quick cleaning).

The last stage is to fill the virobu with 60 oils in machine oil. Then they need to be wiped, dried and may become crusty.

Thermal blued

This option appeared earlier for everyone, but it is simpler than others in Vikonanna, but no less effective. A method was established for heating metal agents until the acid reaction from the metal itself occurs. The heating power depends on the desired result.

The table of representations shows colors that can be selected at different temperature conditions.

To implement thermal processing, you will need machine oil (500 ml), a machine oil bath, pliers, a gas hair dryer and dry servers. Thermal processing of the trace should be performed on a solid or other non-flammable surface.

Robot head:

1. The hairdryer needs to be set to maximum temperature and vibrated over it.
2. The heated part is enclosed in plastic and can be trimmed with pliers.
3. Then pat dry with a serving cloth.
4. Repeat the entire procedure 3 more times from the cob itself.

This is the way to avoid giving the metal a black color. When blackened by this method it is necessary to kill the blackberry, the decorative crow is rarely successful in this way.

Oxidation with citric acid

Blackened with citric acid protects against corrosion, oxides and rust. This is an old method that is suitable for steel with high ductility carbon. If you oxidize a knife in this manner, then in the places where it will be sharpened, everything will be covered. It is not very durable and is suitable for items that are rarely handled.

For whom do you need:

• a pack of citric acid;
• hot water (90-95 degrees);
• machine oil

In a stainless steel container or glass, soak the entire bag with citric acid (20 g), add hot water (about 200 g) and stir thoroughly. The vibrator is locked in the warehouse and deprived of 50 health. After about an hour, you can stop the beginning of the reaction. Bulbs are actively created around the part. The stench can penetrate the surface until it reaches the vibro, so you can periodically (10-15 minutes) break it with a knife so that the stench disappears from the surface.

After 50 minutes, you can remove the part, which will appear after the black color process is completed. It needs to be rinsed, greased with oil and wiped.

Blue steel

The hot crow most often helps to reach the blue color. It appears when heated for three hours. The surface swells with white, yellow, and violet tints, resulting in a beautiful blue color.

Recipe 1

The blackened steel in the home minds in this way conveys the presence of the forge, ideally with automatic blowing. The metal box is lined with birch wood, leaving room for the metal that needs to be processed.

This structure is placed near the forge, which is heated in front. Wash down the metal, wipe it and put it in a box when the vugilla begins to smolder. If there is a bluish color, the part must be pulled out, cool slightly and turn in place. Such manipulations should be performed 3-4 times until the correct cut is obtained.

Recipe 2

This method of maintaining a blue color can be achieved without heat treatment. You need 3 grams of hexacyanoferate (“chervona sil” among the people) and fluorochlorine. To be safe, chemical components must be added to water rather than in bulk.

These words are easily disintegrated and have strong oxidizing properties. Add them in 0.5 liters of water and mix them into one substance. In the villages that are high, the steel is hardened until the required color is available.

Noble gray and black color

Garnier gray color can be extracted using additional nitric acid (a type of salt) and denatured alcohol (a type of alcohol). When you do this, you are satisfied with the melting and the consistency is good. Melt the salt (70 g) on ​​fire, add denatured alcohol (20 g) to it and coat the metal with the mixture, heating it until the correct seal is removed.

You can embellish stainless steel with the help of various oils (wood, tvarina) or wax. I wash the object and fry it in fire. The result is a noble black color and a persistent, dry spit.

Methods of blued metals (19 photos)

Blackened metal, steel and coated surface with a special ball. It gives the virus a singing ferment: black, blue or something else. With this kind of practice, drowning appears. However, this method is widely used due to its practical value: covering objects with a special melt to protect them from corrosion. The process has long been developing an expansion in industry. Actions will stagnate in the household minds.

Bluening methods

There are a number of ways similar processing. In industrial production, the blackening effect is caused by a change in the structural composition of the surface. Applied in a special way. In home minds, it is too expensive and simply impossible to implement such technologies.

However, there are ways to blacken steel at home. For whom there is no need for industrial possession. Everything you need can be found at the store. These methods are presented below.

Hot method

The hot method transfers the infusion high temperature. The metal surface is painted, then scorched, for example, with a blowtorch.

The principle is as simple as possible and has been used for centuries. For the robot, it is enough to use a basic kitchen stove. As the temperature rises, the upper ball interacts with the acid.

Heating of the trace is carried out gradually, gradually bringing up to 400 °C. The surface turns brown and then black. Required oil: olive or zbroyova. It is important to take advantage of its thickness and not to overdo it. Otherwise they will be splashes.

The way in the minds of the home is becoming more and more common through technology. I want to win some advantages:

• The dry effect lasts longer than in the cold method;
• not harmful to health;
• will require little investment.

Before the crazy fell, it is necessary to arrange the virib with a special warehouse, before entering:

• sirka;
• consistency of butter.

Compatibility of components up to twenty times. Apply yakomaga with a thin ball. As a result, the surface becomes even smoother.

There is a simple way to check the blackness of the crow. Soak the penzlik in fresh water and run it over the rough surface. It is the fault of the spittle, but not the speck.

Cold method

Another way of processing - colder crow. It is often vikorized because the virus cannot be seriously enhanced. It takes only a few hours and also doesn’t cost you a lot of money.

The essence lies in coating the surface with a special coating, for example, paroxysmal oxide. Apply, as a rule, with a penzlik. For greater effect, the virib will be enclosed at home. After the Virib procedure:

1. Miyut.
2. Wipe with ganchirs. You need to soak it in alcohol.

Stagnation of oxidizing agents

Є method of vicoristic melting of oxidizing agents:

• nitrates;
• nitrites

Such ferrous metal in the home is transferred from melting. The virus remains in the new place until the surface rises characteristic color. When working, remember that this is not safe for your health. They can be replaced with offensive divisions:

• hot saltines;
• puddles.

Acts of particularity

The crow began to not become anything coherent in the minds of the home. Oxidizing agents are used for processing and other metal viruses:

• chavunnih;
• copper ones, which develop an intense red color.

It is low in particularity, as it is important to remember:

1. Since the germs are heat-sensitive or hardened, they should not be touched. Voroninnya to eat up the displays.
2. To complete the process, do not forget to erase the virus in a special way. After drying, you need to butter it.
3. In stores it is not important to know the necessary words, for example, saltpeter, citric acid.
4. Blackness can also be identified. For which you need a special olive.

Preparation is important:

1. Before starting the cob, it is necessary to clean the surface and polish it.
2. Sprinkle with special ingredients.
3. You must not forget about gum gloves for hand protection. You can’t rush to the ruined virobu.
4. Create ventilation and hood.
5. Settle down with the relevant authorities. The volume is responsible for allowing the liquids to be drowned throughout. Choose a material that is not afraid of stools: glass, porcelain, stainless steel, earthenware.

As for color, it may also be important for certain viruses. You can select different types of bark: from yellow to black, from yellow to dark. So, strictly speaking, black and raven are not the same.

To achieve the required color, you will need to further clarify the components of the components or increase your attention to the heat treatment mode. For example, one of the methods is offensive:

1. Take copper nitrate (70 g) and alcohol denatured alcohol (30 g).
2. Heat it up so high it won't melt.
3. Add denatured alcohol.
4. Tsіyu madness cover the virib.
5. Heat until the necessary color comes out. The color will vary.

Secrets of the Raven

There are a lot of crow recipes. Kozhen Meister his will who can be more cunning. For a long time, recipes for blued steel were often trimmed in a dungeon. Today you can find a variety of recipes for any taste.

Cold blued

You can aim the butt of the cold crow's box:

1. Take a liter of water (distilled), two types of acid: 30% hydrochloric acid (4 g), 69% nitric acid (13.5 g). Trivalent salt chloride (170 g) and divalent copper sulfate (4 g) are also added.
2. I'm going to scrape the surface and leave it for any hour. Chem dovshe - tim better.
3. The area is cleaned using water steam and a brush.
4. Everything is repeated until the result does not appear as expected. Work up to 10-20 times.

Recipe with oxidizer

For the butt, you can apply the following recipe for meadow rose:

1. You need caustic soda (400 g), sodium nitrate (10 g), water (600 ml).
2. Pour the sum for 30 minutes or more.
3. Then the surface is washed well, dried, and the bits are anointed with olive oil. The meadow will not be swept away until the end, if there is a flood.

Be careful while working. Hot speeches and chemicals from the building harm your health or freeze it. It is important not to forget about the correct selection of capacity, basic clothing and basic safety techniques.

Voroninnya is the process of removing the ball from the oxide of the car. They are also called oxidized, black and blue. It’s darker, it’s more blackish, but there are different colors.
Basically, the blackened steel is used as a decorative coating, in order to protect the steel from corrosion just before clicking.

I'll show you a way to make a simple crow knife at home, using a few readily available ingredients.
What is needed?

• - strength 0.5 liters;
• - Citric acid 50 grams (can be purchased at any grocery store).

The proportions are approximate, so it won’t be difficult to get it right. Place everything in a large bowl in which you hold your blade. It is important to know that increased concentrations of citric acid accelerate the oxidation process, otherwise, at high concentrations, they can lead to uneven coating.

Crow knife process

We take curses of dishes, beyond the size of a knife, so that it can be completely locked up at the hands of the authorities.
We boil water at the kettle. Then we take it and carefully pour it into the jar. Here we need to be careful, the bank may lose fragments. To avoid this, you can pour some sprinkling into the bottom of the cob and let the jar warm up, then top it up with some.

Then add citric acid to the water and stir thoroughly until completely dissolved.
Before you sharpen the blade, wipe it with alcohol to remove all traces of fat and debris.
We tighten the blade of the knife.

After 1-2 weeks, the reaction will begin, as it will be marked by the number of bulbs.

Voroninnya borrows approximately 30 to 60 rubles. Once again, stay within your reach until the color of the coating and the grade of steel of the knife.
Throughout the entire process, it is necessary to do the following:

• - Remove the knife from the skin of 10 wings and wipe it with soft paper or cloth paper, removing a black coating from the surface.
• - About every 1-2 weeks, it is necessary to steal the sword from the robber, thereby releasing the large bulbs of gas from the forest. This will ensure the evenness of the coating.

Once finished, if you are satisfied with the color of the coating, you need to wipe the blade with oil. Stop the reaction and cover it with the same thing.
The blued edge of the knife is now complete.

Finally, I would like to add:
- Do not inhale the pores of gases when blued, the fragments will smell bad. Use ventilation as often as possible, or even open a window in the room.
- For a stable process, the water is hot. Crows do not go near cold water. The strength is not heavy, but it may be 80 degrees Celsius.

If you have had minor problems, don’t worry, the smell will go away after the first or other use.
Keep the stand up this way and it will last for more than one time.

It is important to me that it is impossible to carry out crow metal processing in households, and that such an operation only works in production. In fact, this is the idea of ​​Milkova, and at home, with the help of simple improvised methods, you can only remove the iron from the iron, and also give it a rich black or blue color. Now, let’s look at the way the Vikonian works on the blued finish on the butt of the knife.

Features of home technology

It is entirely natural that the rise of the crow knife in the home minds of industrial methods is invisible from an economical or technical point of view. In production, black steel is achieved by changing the structure of the upper balls of the metal using additional chemicals. At home, using this method is ineffective, but it is very simple, but you can achieve effective ways of using a black knife in your home.

Bluening methods

There are three ways to burnish steel:

• It’s colder - if the vibrator succumbs to the bluing, it doesn’t feel the thermal surge.
• Hot - the process of crow vibration is subject to any kind of thermal processing.
• Oxidizing is the most convenient method for home-made processing; the fragments must be mixed with chemicals and heated to high temperatures.

Now let's take a look at how you can use a blued knife in your home. Before drying using any of these methods, it is necessary to degrease the steel with alcohol and wipe the flannel dry.

Citric acid

This way you can protect the metal from corrosion and give it a rich black color. The method of burnishing steel with the help of citric acid will take a long time to finish, but is not suitable for high-carbon metals. In addition, it is important to know that blackening a knife in citric acid works better if the knife serves purely decorative functions, since this method of blackening metal is not resistant and, when sharpened, everything becomes very hard Come on.

In order to use a black knife to add citric acid, you will need:

• citric acid – 1 sachet;
• water, heated to 90 - 95 degrees;
• machine oil;

Pour hot water into stainless steel dishes and dissolve citric acid in proportions of 1/10, so that for 1 part citric acid 10 parts water. Place the bottom in water and cover it with 50 degrees. Periodically crumble the bottom, so that the bulbs that form on the surface will be difficult to access again and will interfere with the draining process. After completing 50 pieces, the steel turns black, which means that the blackening process has reached its end. It is necessary to rinse the knife in clean water, lubricate it with machine oil and wipe dry.

This method of crowing is intended to protect the metal from corrosion, but rather to be of a decorative nature through those that, at the least amount of influx, will need to be removed and the procedure of crowing the knife will need to be carried out again.

Coca Cola

Another way to cut a black knife at home is to use Coca-Cola. Before speaking, this is even more universal and is most often used not for any direct reasons, but for a variety of reasons, including metals. Also, for a crow knife in Coca Cola you will need:

• glass or metal container made of stainless steel;
• Coca Cola;

The burnishing process is similar to the first one, but does not involve heating. To make a crow in this way, you need to place one or two of the bottom tips on top, periodically turning them over and releasing the bulbs. After this, you need to replace the tip with a new one and re-place the bottom there. This procedure must be continued until the garish black color wears off, even as the season progresses, every two days changing. Make sure that the entire surface of the Coca-Cola covers the bottom 5 centimeters and do not forget to turn it over periodically, as the bulbs that accumulate on the surface of the knife will interfere with the blackening process.

If you need to thoroughly rinse it with clean water, you can use extra milk and anoint it with machine or towel oil. Without oil, rust already appears on the metal, and it becomes visible even during the drying process.

This method of finishing is best suited for thin, smooth surfaces, for example, using a chopping knife in this way allows you to achieve a more even finish on any folding surface without any bulges or wrinkles. Cream Coca-Cola can be mixed with Pepsi-Cola. Blackening is charged for the container of phosphoric acid, which is included in the storage of these drinks.

This is the way to use a black knife to finish the job. If small stains appear during operation, do not clean the visors. In addition, the product comes out absolutely smooth, without ever succumbing to regular influxes. The only disadvantage of such a raven can be called the fact that it takes up to an hour and requires constant contact with the virus (it is necessary to turn it up to 4 - 6 times per sample), so that in other cases the bulbs come out clear and inclusions on the surface of the knife.

Ottoic acid

The burnishing of a knife in general practically does not differ in any way from the two previous methods. It is also necessary to place it in the mixture and periodically shake and turn it over to prevent the bulbs from settling on the surface of the dough.

In addition, if the handle of the knife is plastic or plastic, it is necessary to protect it when wet, for example, by covering it with paraffin.

Blackening of a knife can also be carried out in a heated medium, so this method will be more similar not to blackening, but to etching metal.

The bottom can not be dipped into the ointment completely, but buried in the fleecy fabric, which has been well soaked in the oot, but this method is more labor-intensive, since the fabric must be periodically wetted.

To come out looking beautiful, not all black, but rather a dark gray color. Such a black knife is not particularly useful, so it is best used for decorative knives and other metal interior items.

It should also be said that it is not just any kind of metal that can be blackened, but rather carbohydrates. Therefore, the first year, respectfully stitch after him, as steel is led. Please note that white inclusions appear on the surface; this method, unfortunately, is not suitable for this metal; the inclusions will not disappear, but will become more contrasting.

Rust varnish

The black knife bears a rusty varnish, reflecting both its achievements and shortcomings. The main advantage of this method is that it is possible to burnish knives on tin solder, since all the previous methods are not suitable for these purposes - the tin either breaks down or does not change its color. In addition, with the help of rusty varnish, you can apply a fine burnish to the knife to burnish the entire blade or handle. The ball is coated to a high quality, polished using advanced methods, and the steel itself has such a matte black finish.

Few of the blued knives in this way are those that knives, especially industrial ones, are most often made from different alloys, and the rusty varnish is very sensitive to the home, so that the leather metal in the alloy is barbed in its color and on the surface. the robe appears red-brown and stormy we splash. If you notice such an effect when applying varnish, it is necessary to remove the varnish before oiling the surface, otherwise you will not be able to see any stains or seals.

Other important shortcomings include the fact that this method of crowing is sensitive to various nuances of the process: the amount of fat, the temperature of drying, the time of crowing. In addition, the process is very difficult and emphasizes your absolute presence, so the varnish must be applied several times and immediately after drying, steam it, and then rinse under running water. . All these procedures must be repeated until you are satisfied with the final result. After that, you need to place the knife in boiling water for 5 minutes, and then wait until it is finished again, and then proceed to the process of polishing with soft flannel gantry.

In addition to overcooked foods, in the home, use the methods of a crow knife for additional frying. Before twisting the knife in this way, it must be coated with flaxseed oil, shortening or wax. After this, you need to fry it well on fire. Place it in the original kitchen frying pan, and then wash the dishes after sealing them.

Before using this method, you can first dilute the bottom with copper sulfate and ammonia: dilute 100 g of vitriol and 10 g of ammonia in one liter of clean distilled or standing water. The sharpening and sharpening of the knife must be carried out several times until you remove the necessary color from the metal.

Chemically blued

The chopping of a knife in this way can only be carried out due to exhaust hood and ventilation, which in another case may not be safe for health!

1. Place the mixture of nitrate and caustic soda (30 g of nitrate and 100 g of soda) heated to 140 - 160 degrees and soak it there for at least half a day. With this method, the black color comes out dark and deep black, which gives it a blue color.
2. If necessary, dilute a high concentration of potassium hydroxide or sodium hydroxide and place the lower concentration there. This method will give a bluish melt on the surface of the knife.

Oiling

Cover the bottom with oil - you can zastosovat lyana, machine, zbroyova, navit sonyashnikova. You can apply the oil either with a pencil or simply by wetting it in a knife. Afterwards, fry the bottom in the oven to 400 degrees. After completion, reverse the result and if the color is insufficient, repeat the procedure. When finished, cool the bottom and remove the oil with a soft ganache.

Visnovok

As you can see, the ways in which black metal reaches household minds are varied. The only problem may be that you don’t know how a particular metal will behave when used in the singing method. However, most of the coatings can still be removed from the surface of the metal, which means that the object will not be permanently sealed no matter what.

Which of the most varied methods of vikorystvat only you can choose, but all of them deserve respect and allow you to achieve good results.

What is a crow's bird? What does it give and how to make money at home? This is the kind of food that will be harvested from the rich cobs in your path of refinement as a source of wisdom. Burnishing steel from the beginning, according to the technologist, is the process of applying a thin coating to the metal through a chemical reaction.

Most of this process can only be seen on one side - the blued barrel looks beautiful. However, there are at least two additional advantages: metal coated with spit is less susceptible to corrosion, in addition, it can cover stains, which provides additional masking for damage. The grievances of these officials are extremely important for a true thinker. Therefore, crow breeding is an important process.

Features of technology

It is often possible to finish milk just a little, because the crow’s grain is more likely to be lost in factory minds. This is not a completely correct statement. Thus, with industrial processing, a change in the chemical composition of the upper ball of metal becomes possible, and the oxide, which is important in this method, plays a major drying role.

It is not easy to reach the bright ferrous metal in the household minds, but it is impossible to say that the oxidation of steel in the household minds with the ancient industry standards is impossible, but there are many other ways to about giving the same effect and as many as possible before being stuck at home. All these “home” technologies can be divided into three groups based on the basic principles of the process.

Commonly seen:

• colder blued steel;
• hot blued steel;
• oxidize the sample.

Rules and safety techniques

Whatever the case, you will have to undergo a number of procedures in the following order:

• Cleans the surface on which blued steel passes.
• Sanding the surface until it is perfect.
• Low-fat (obov'yazkovo), after this stage, apply a trace of the gum mittens.
• Construction of materials for blued metal in home washes.
• Finishing of the metal surface.

It is completely obvious that the crow has begun to be relegated to the category of even unsafe work in household minds, and therefore it is more important to maintain the old rules of life. First of all, it should be understood that the active and aggressive chemical substances do not take place, then the soil for the crow must be preserved in a specially designed dish for this purpose, however, The entire process is also carried out in a container specially prepared for this purpose.

It is important to remember that there are a lot of storage facilities for the removal of acid and for this reason the dishes are made of glass, porcelain or earthenware, and metal containers should not be frozen.

In other words, in the process of preparing black barrels, mechanical cleaning of the metal is carried out, which means that the person who completes this work is responsible for the protection of mechanical damage to the skin and eyes.

Also, such actions should be carried out in an area that is well ventilated, since handling saws and chemical reagents is not harmful to anyone. To clean and sand the surface using the recommended methods: pumice, emery paper and fine-grained sand.

When starting work, be sure to clearly understand the order and sequence of your actions, otherwise you may end up with zipping. It is also worth remembering that black metal does not contain very dangerous and aggressive chemical reagents, contact with the skin can cause serious chemical reactions.

Cold Crow: features, advantages, shortcomings

Often add to the food to burnish steel at home, which is an option for the cold burnishing method. As a rule, this method is used in such situations, if the part does not suffer from strong mechanical surges. It is clear from the name that such a process of blackening stems in home washes can be carried out without thermal infusion. In reality, there will be a lot of discord.

For additional help, that Penzlik

There are a number of industrial options for ready-made mixtures for applying them to the metal surface with a spray gun. This is useful for crow "Raven 3" of ham vibration, and also useful for crow imported sum "Paris oxide".

The advantages can be seen with the naked eye. This is the simplicity of the process, as well as the fact that for the raven there is no need to cook on your own, so you can ensure minimal safety and security during the process.

This method also has some disadvantages. It’s very easy to penetrate all the “cracks” of the part with a pencil thanks to its folding configuration. For “smoothness” the product will require additional polishing. Well, the best thing about such blued barrels is those that will cause minor mechanical damage to the track and the processing will have to be repeated.

Nuring method

Another option is to transfer the wires to blackened metal to repair parts. The main advantage of this method is that the liquid penetrates all the crevices of the part and covers it with an even layer of dryness. In another way, the liquid does not splatter, like in the first application when applied with a pencil.

Recipes for cold application of dry melt can be taken:

1. Saliz chloride (FeCl 3) – 75 grams; ethanol (ethyl alcohol, medicinal alcohol C 2 H 5 OH) – 30 grams; copper sulfate (copper sulfate, CuSO 4 (anhydrous white color) or CuSO 4 *5H 2 O (blue)), nitric acid (HNO 3) - 20 grams each.
2. Saliz chloride (FeCl 3) – 170 grams; nitric acid (HNO 3) – 13.5 grams; hydrochloric acid (HCl) and copper sulfate, copper sulfate, CuSO 4 (anhydrous white color) or CuSO 4 *5H 2 O (blue)) - 4 grams each.

This method is not suitable for those who want to know how to bury the bottom, since the fragments are not resistant to mechanical melting and will rub off quickly. To solve the problem of blueing a towel, it is recommended to use additional blueing and rusty varnish, as one of the most effective and least expensive methods. The essence of the method lies in treating the part with an already active corrosive medium - “rusty varnish”. Tsiu sumish varto schatku prep.

It is recommended to do everything under a hood or outside from a ventilated side, so as not to inhale the dangerous gases that are created during the reaction. Place 12 grams of hydrochloric acid (HCl), as well as nitric acid (HNO 3) at a quantity of 20 grams (remember, it’s not the product, but the difference in acidity) that is placed on the surface of the dishes. Add 30 grams of salivary scale (irzhi) and 5 grams of salivary thirsty to this mixture of acids.

The reaction needs to go through. Then, before discarding the reaction products, add 50 g of distilled water and ethyl alcohol (medical alcohol C 2 H 5 OH).

It is necessary to deprive the items for 12 years and after this the need to reinforce the items from scale and salts that have fallen into the siege. Now for blackening at home, this method is to place the part at the edges and press until the part becomes black. After this part, you need to rinse it with water and use a brush to remove any traces of dirt. As a result, even the nasty result of the chemical crow is possessed.

Both in the first stage (with a brush), and in the other (stagnant damage), after all procedures, the blued parts must be carefully taken into account according to certain conditions. Unfortunately, this method is not suitable for those who are trying to figure out how to bury the bottom, since the fragments are so difficult to cover and easy to wipe off.

Hot crow: features, achievements, shortcomings

Many people, especially the smart ones, are respected for the best way to work black towels, including the hot method, which is always the correct method. The argument is very simple. In virobu, which is burnished in a hot way, the coating is preserved much longer. Another advantage of this method is the absence of wasteful vapors.

This method is often called bluing in oil, which actually explains the technology of the process. The technology is quite simple and the blued steel is made with your own hands using this method and it is easy to achieve.

For the beginning, the detail is painted the more, the more beautifully. After this, the part is encrusted in an oil (itself gave the name to the method as blackened steel in an oil). This can be butillyana, olive or zbroyova oliya. It is important to use original machine oil.

After the part has been rubbed for about ten seconds, the part is removed, and it is obligatory to let it drain on its own, otherwise it will get splashed. The approaching crust lies in the “baked” oil on the surface. For this purpose I used a blowtorch. The important moment when the steel is blued in oil is at the designated moment when the product is ready.

It is clear that the masters say that baking is required at the moment when the part begins to change its color from brown to black. Burnishing steel in oil is one of the oldest and most proven methods of protecting metals from corrosion, without failing the masters for centuries, without failing at once.

Processing of oxidation: features, advantages, shortcomings

For a food chemist, how to coat steel is not very good, literally first, because it oxidizes it. The only downside to this is that it requires heating to the melting point, but this is not always possible at home. Most often, such processing is carried out from stagnation of nitrates, the mark and name is raven in saltpeter. If you really want to choose oxidizers, there is a great choice and blueing in saltpeter in home minds is not the only effective method with the use of oxidizers.

For recipes follow:

1. Sodium hydroxide (NaOH) - 2.8 grams; disodium hydrogen phosphate (Na 2 HPO 4) – 100 grams; sodium nitrate (NaNO 3) - 50 grams (Rozrahunok is applied to 1 liter of water);
2. Sodium hydroxide (NaOH) – 400; Potassium nitrate (KNO 3) and sodium nitrate (NaNO 3) - 10 grams each for the skin (Disease is applied to 0.63 liters of water).

An hour of confinement at the home is no less than 30 hours. This method is suitable for a crow's knife at home, as long as it allows you to remove the surface of the coating without damaging the hardness of the metal.

For all its advantages, the method of oxidizing metals with vicarious oxidizing agents is expensive and difficult for beginners, as it requires good knowledge of chemistry and its properties. Please note that burnished stainless steel is produced by other methods that are not interconnected with these methods.
