What are the tungsten carbide spraying? Is tungsten carbide spraying wear resistant

Sichuan Chengyuan Mechanical and Electrical Engineering, Zhengzhou Kaisida Machinery.

Tungsten carbide is an organic compound composed of tungsten and carbon, carbon is negative tetravalent, and tungsten is positive tetravalent. Tungsten carbide is a black hexagonal crystal with metallic luster, and its hardness is similar to that of diamond, making it a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, and is easily soluble in the mixed acid of nitric acid and hydrofluoric acid.

Pure tungsten carbide is brittle, and if a small amount of titanium, cobalt and other metals are added, brittleness can be reduced.

Tungsten carbide, which is used as a steel cutting tool, is often added with titanium carbide, tantalum carbide or a mixture of them to improve the anti-knock ability.

Tungsten carbide is chemically stable. Tungsten carbide powder is used in cemented carbide production materials. More than 500 in the air will start active oxidation, and the antioxidant capacity is weak. High acid resistance.

Tungsten carbide. Spraying is to combine tungsten carbide alloy with the substrate in the form of coating to form tungsten carbide wear-resistant layer, and tungsten carbide spraying can be classified as follows according to different processes

1: JP8000 tungsten carbide spraying process, Beijing Naimo Company added a coating with a hardness of HV1200 hardness with JP8000 equipment.

2: KN3000 tungsten carbide spraying process is made of oxyacetylene.

The process is sprayed with a tungsten carbide coating.

3: Vacuum tungsten carbide atomization treatment, with high-precision tungsten carbide coating.

Tungsten carbide coating has the characteristics of high hardness, good wear resistance and low thermal deformation.

Metal surface sprayingSilicon carbideDifference with tungsten carbide: coated silicon carbide has higher hardness, and coated tungsten carbide has lower hardness. Silicon carbide has a high thermal conductivity.

Low coefficient of thermal expansion, excellent oxidation resistance.

and thermal shock resistance, which can significantly improve the heating and cooling rate of the mold in the glass molding process, reduce the dimensional accuracy and the change of Crypto surface quality under high temperature thermal cycling, and is considered to be the most potential mold core substrate.

Advantages of silicon carbide

High hardness: The hardness of silicon carbide is much higher than that of tungsten carbide, even under extreme high temperature and pressure, it also has super wear resistance and complete impermeability, high hardness also means that it will not pollute the medium in high-purity applications, high density and low porosity: the product density is large, and it can be processed into an ideal mirror effect.

Excellent thermal shock resistance: excellent thermal conductivity and consistently low thermal expansion coefficient, as well as the intrinsic temperature gradient of minimal heat dissipation, make silicon carbide have very excellent thermal shock resistance, so it is more adaptable to rapid thermal cycling, heating and cooling than other materials.

High temperature stability: It can operate under high temperature conditions that other materials cannot meet, and it does not deform at high temperature, incomparable high temperature creep resistance: it can minimize the deformation of the mold, and excellent oxidation resistance: it can achieve a long service life.

Tungsten carbide. Wear-resistant, because the higher the hardness, the better the wear resistance.

Mohs hardness of zirconia.

It has excellent physical and chemical properties such as high hardness, high strength, high toughness, high wear resistance and chemical corrosion resistance. Tungsten carbide has a very high hardness on the Mohs scale, and its wear resistance and corrosion resistance are better than those of zirconia. Generally, the higher the hardness, the better the wear resistance.

Tungsten carbide is a compound composed of tungsten and carbon. It is a black hexagonal crystal with a metallic luster, a hard beat similar to that of diamond, and a good conductor of electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, but soluble in nitric acid and hydrofluoric acid.

Tungsten carbide used as steel knives is often added with titanium carbide, tantalum carbide or their mixtures to improve its anti-knock ability. Chemical properties of tungsten carbide.

In addition to tungsten carbide, the coatings for metal equipment linings are mainly as follows:

1.Alumina: Alumina is a kind of corrosion-resistant, wear-resistant heat-resistant ceramic material, which has the characteristics of high temperature oxidation resistance, high temperature hardness, low friction coefficient, good electrical insulation and high dielectric strength, and is suitable for high temperature and high pressure environments.

2.Zirconia: Zirconia has the characteristics of good chemical stability, strength and hardness, high temperature stability and high specific strength.

3.Silicon nitride: Silicon nitride is a new type of material, which has the characteristics of high hardness, wear resistance, high temperature resistance, corrosion resistance, oxidation resistance and high mechanical strength, and is widely used in the lining coating of pure metal equipment.

4.Composite coatings: Composite Muzhou material coatings are composed of different materials, which can have the characteristics of a variety of materials, such as wear resistance, corrosion resistance, high temperature resistance, electrical insulation, etc., which can be selected according to actual needs.

Of course, the type of coating used in the lining of metal equipment also needs to be comprehensively evaluated according to the specific application needs and use environment to find the best solution.

In addition to tungsten carbide, there are other materials such as alumina and boron nitride in the coating process of metal equipment lining. These materials can form a corrosion-resistant, chemical-resistant protective layer in the metal lining, increasing the life of the metal. The metal equipment lining spraying process is a widely used technology in modern industry, which can effectively improve the corrosion resistance and chemical corrosion resistance of Qishan metal lining.

This process usually involves chemically or physically treating the metal and then spraying it onto the inner wall of the metal to form a protective layer of metal. The materials of the metal inner separator include tungsten carbide, alumina and boron nitride, which can effectively protect the metal inner layer from chemical or organic lead corrosion.

How many areas can 1kg of tungsten carbide powder be sprayed? Hello, I am glad to answer your question for <> 1kg of tungsten carbide powder can be sprayed sheet metal spraying powder dosage calculation paint film thickness is 60-80 microns, under normal circumstances, 1kg of powder coating can be sprayed 5-8 square meters. Of course, the spraying area is not only related to the coating, but also has a lot to do with the quality of the operator, whether the equipment is advanced, whether the grounding is good, etc., the normal calculation of 1kg = 5 square in 75 m, that is, 1 square =, generally a box of powder in 20-25kg a box, first calculate how many squares, you can calculate how much powder is needed.

First of all, you have to calculate the total area of your aluminum alloy, and then see how many kilograms of powder coating you use after spraying, and the area of powder weight = 1kg of powder spraying area! I hope mine can help you <>

Do you have any other questions?
