Chromium diboride (CrB_2) coating has high melting point, high hardness, high wear resistance and corrosion resistance,
Coupled with its good chemical inertness and the characteristics of not easy to bond with the metal, as hard
Protective coatings are expected to meet these special chip processing requirements.
Application
1. Used as wear resistant, high temperature resistant oxidation coating and neutron absorption coating in nuclear reactors. Used for ceramic, molten spray on metal and ceramic surface, forming wear – resistant, corrosion – resistant film, semiconductor film. Chromium boride and alumina are sintered or hot-pressed in a micro-oxidation atmosphere, which has the practical value of high temperature wear resistance.
2. Used for ceramics, melting and spraying on the surface of metal and ceramics, forming wear – resistant and corrosion – resistant films. Used for spraying semiconductor film.
