Langfeng metal is Manufacturers of thermal spray powder coating, thermal spraying material, thermal spray coatings, thermal spray powders.
Zirconium carbide powder produced, hafnium carbide powder, titanium carbide powder, vanadium carbide powder, tantalum carbide powder, molybdenum carbide powder and the chromium carbide powder, can be applied to cutting tool materials, cermets, metals and ceramic materials Ceramic Coating. It also can be used in carbide cutting tools as a bonding material.
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．
