Silicon carbide powder for wear resistance coating

Silicon carbide is a typical covalent bond compound. It is an artificial material that doesn’t exist in nature. Silicon carbide materials have many excellent properties, such as abrasive resistance, high-temperature resistance, corrosion resistance, high thermal conductivity, high chemical stability, wide band gap, and high electron mobility. Silicon carbide grain and powder get extraordinary hardness. Thus it is initially used in various grinding tools, such as grinding wheels, abrasive cloth, abrasive sanding paper, etc. It works widely in material processing and grinding in the mechanical industry. Especially for fragile and hard substrate materials such as granite, stones, marble, etc.

The hardness of silicon carbide is second only to diamond, and it has strong wear resistance. It is an ideal material for wear-resistant pipes, impellers, pump chambers, cyclones, and bucket liners. Silicon carbide powder owns high strength, high hardness, a small friction coefficient, and high-temperature resistance. Black silicon carbide powder is particularly suitable for sealing rings and other wear-resistant parts with poor working conditions. When the silicon carbide powder is coated on the inner wall of the turbine impeller or cylinder block with a special process, its wear resistance can be improved and its service life can be extended by 1~2 times.
