This coating includes plasma spraying ceramic wear-resistant coating and supersonic flame spraying carbide cermet coating.

The ceramic materials which plasma coating use are mainly titanium oxide and chromic oxide. These kinds of materials have the excellent performance of high hardness, corrosion resistance, good heat resistance and low friction coefficient etc. So the coating has excellent and stable wear resistance and antifriction performance.

Cermet coating which composites nickel-chrome, cobalt base metal phase and tungsten carbide, chromium carbide etc. hard phase ceramic materials, has the characteristics of high hardness, good toughness etc.
