What are the uses of chromium carbide?
Chromium carbide is a ceramic compound that exists in many chemical components. Under standard conditions, it exists as a gray solid. It is very hard and corrosion resistant. It is also a refractory compound, which means it can maintain its strength at high temperatures. So, what are the uses of chromium carbide?
What are the uses of chromium carbide?
1. Chromium carbide can be used for surface treatment of metal parts. Through a technique called thermal spraying, chromium is used to coat the surface of another metal and mixed with solid nickel chromium powder. Then this mixture is heated to a very high temperature and sprayed onto the coated object, where a protective layer is formed. This layer is essentially its own metal matrix composite material, which is embedded in a nickel-chromium matrix. The matrix itself contributes to the corrosion resistance of the coating, because the metal form of nickel-chromium has corrosion resistance. After spraying the coating, the coated parts need to undergo diffusion heat treatment, to obtain the bond strength and hardness with the substrate, another technique uses chromium carbide in the form of cover plates. These are prefabricated chromium carbide-coated steel plates designed to be welded to existing structures or machines to improve performance.
2. Chromium carbide is used as an additive in cutting tools made of cemented carbide to increase hardness by preventing the growth of large particles. The main component of most superhard cutting tools is tungsten carbide, which is combined with other carbides such as titanium carbide, Niobium carbide and chromium carbide are combined and sintered with cobalt matrix to prevent the formation of large grains in composite materials, which leads to a fine grain structure with excellent hardness, the accidental formation of chromium carbide in stainless steel and other alloys can cause intergranular corrosion. It is a high-melting material with good wear resistance, corrosion resistance and oxidation resistance in high-temperature environments. It can be used as plasma spraying nickel-chromium The high-temperature, wear-resistant, anti-oxidation and acid-resistant coating of cemented carbide particles made of alloy is widely used in aero-engines and petrochemical machinery, which can greatly extend the mechanical life, it is also commonly used as a grain refiner for cemented carbides and other wear-resistant and corrosion-resistant components, based on cermets, which have excellent oxidation resistance at high temperatures.
3. Used for chromium carbide ceramics. As a melt-blown material, coarse chromium carbide forms a melt-blown film on the surface of metals and ceramics, giving the latter wear-resistant, heat-resistant, and corrosion-resistant properties. It is widely used in aero-engines and petrochemical machinery and equipment, greatly extending the mechanical life. It is also used for spraying semiconductor films.
the use of chromium carbide scene is what kind?
1. Wear-resistant film, semiconductor film.
2. In the production of cemented carbide, it can not only refine the grains, but also improve the strength and hardness of the alloy, and significantly improve the corrosion resistance of the alloy. It is widely used as corrosion-resistant alloy structural materials (instruments, valves, sealing rings, etc.) In industrial production, it is used for spray welding and surfacing of hard surface solder that requires both corrosion resistance and high wear resistance; it is widely used in smelting and producing special steels such as stainless steel, heat-resistant steel, corrosion-resistant steel, and alloy steel.
