Chromium carbide is widely used, because of its various advantages, it is also a very popular product in the market. But it also has a lot of need to know when using knowledge, after all, there are many users do not understand these. The next small series for everyone to introduce the role of chromium carbide? If you are interested, you can read it.

Although chromium carbide is widely used, most readers still don't know enough when they see this product. Especially for its characteristics. Just today we take this opportunity to tell you about it. First of all, chromium carbide is just a ceramic compound that exists as a gray solid under standard conditions. Very hard and corrosion resistant. It is also a more refractory compound, which means it maintains strength even at high temperatures. These properties make it a useful additive for metal alloys because the chromium carbide crystals attached to the metal surface improve the wear and corrosion resistance of the metal and maintain these properties at high temperatures. A hard and common compound used for this purpose is Cr3C2. In addition, this product is a gray powder with metallic luster, orthorhombic system, density 6.68g/cm3, melting point 1890 ℃, boiling point 3800 ℃, in high temperature environment has good slip resistance and corrosion resistance; easy to follow. It belongs to the cermet genus. What you need to know when using is that chromium carbide is a high melting point material with good wear resistance, corrosion resistance and oxidation resistance in high temperature environments. It is made of cemented carbide nickel-chromium particles. The dispersion method can be used as a heat-resistant, anti-oxidation, acid-resistant coating.

Therefore, chromium carbide is widely used in aircraft engines and petrochemical machinery, which can greatly improve the service life of machinery. It is also commonly used as a grain refiner for cemented carbides and other wear and corrosion resistant parts. Cr3C2-based cermets have excellent oxidation resistance at high temperatures. Due to its many advantages, chromium carbide can also be used for surface treatment of metal parts. Chromium carbide is used to coat the surface of another metal in a technique called thermal spraying. Cr3C2 powder is mixed with solid nickel chromium. This mixture is then heated to a very high temperature and sprayed onto the object to be painted, forming a protective layer. This layer is essentially its own metal matrix composite consisting of Cr3C2 hard ceramic particles embedded in a nickel-chromium matrix. This is because the substrate itself contributes to the corrosion resistance of the coating, as the metallic form of nickel-chromium is resistant to corrosion. After the overspray coating, the coated part is subjected to a diffusion heat treatment to obtain results in terms of coupling strength and hardness with the base metal. Chromium Carbide Another technique uses chromium carbide in the form of a panel. Please note that these are prefabricated chromium carbide coated steel plates designed to be welded to existing structures or machinery to improve performance.

After the introduction of the above content, we also have a further understanding of the role of chromium carbide. When I see him again in the future, I will not feel strange, and there will be no frequent problems in the process of using it. Well, that's all for today's content. I believe it will bring more wonderful knowledge points.
