About Chromium Carbide Powder

Chromium carbide,Chemical formula Cr3C2,Molecular weight 180.02,Carbon content 13.344%,Density 6.68 g/cm3, Melting point 1890ºC,Boiling point:3800ºC.Chromium carbide is gray powder with rhombic system structure,which is undissoluble in water and resistant to acid and alkali .It is high melting-point inorganic material with wear resistance,corrosion resistance and resistance to oxidation at elevated temperature(1000~ 1100ºC),and is expansively used as thermal spray material to protect the metal surface,and as additive to fine the cemented carbide crystal and some other wear-resistant and corrosion—resistant organ as well.Cr3C2  cermet has excellent resistance to oxidation at high temperature.The cermets surface only will darken in some sort after exposed at 980 ºC for 5 hours.However,18-8 stainless steel destroyed obviously and the WC-6Co alloy oxidized entirely at the same condition.
