Chromium Carbide Powder (Cr2C) Sintered Chromium Carbide/Redox
Basic information:
The production process consists of chromium and carbon carbonized in a vacuum. Its molecular formula is Cr7C3, its melting point is 1665 ° C (the theoretical weight of carbon is 10%), and its density is 6.9g/cm³. The melting point of Cr3C2 is 1890ºC (the theoretical weight of carbon is 13%), the density is 6.68g/cm³, the hardness is above HV2200, and the chromium carbide is non-toxic, non-corrosion, non-oxidation, tasteless. The appearance color of chromium carbide is silver gray. The lattice of chromium carbide is positive and negative, with a melting point of 1895 ° C and a boiling point of 3800 ° C. High wear resistance, corrosion resistance and high temperature resistance.

Application:
1, It is a high melting point material with good wear resistance, corrosion resistance and oxidation resistance in high temperature environment, carbide particles made of nickel-chromium alloy, using plasma spraying method, can be used as high temperature resistance, wear resistance, oxidation resistance and acid resistance coating, widely used in aircraft engines and petrochemical machinery devices, can greatly improve the life of machinery. It is also commonly used as a grain refiner of cemented carbide and other wear-resistant and corrosion-resistant components. Cermet based on Cr3C2 has excellent oxidation resistance at high temperature.
2, Used for chromium carbide ceramics. Coarse-grained chromium carbide is used as melt-blown material to form melt-blown film on the surface of metal and ceramic, giving the latter wear resistance, heat resistance, corrosion resistance and other properties, and is widely used in aircraft engines and petrochemical machinery devices to greatly improve the mechanical life. It is also used to spray semiconductor films.
