Chromium Carbide Cr3C2 can be used as high temperature resistant, wear-resistant, oxidation resistant and acid resistant coating for aircraft engines and petrochemical mechanical components and devices to greatly improve the service life of machinery. Chromium Carbide Cr3C2 is commonly used as an additive of grain refiner to inhibit the growth of the alloy grains, and fine the crystalline grain in the production of cemented carbide and other wear-resistant and corrosion-resistant components. It is also expansively used to spray semiconductor film and as thermal spray material to protect the metal surface, or plasma spray in the metallurgy, electric power and petrochemical field.
