The application of boron carbide in coating

The application of boron carbide in coating
Boron carbide coating has low density and high hardness. At 1100 ° C, its hardness even exceeds diamonds and cubic boron nitride, and boron -carbonized chemical performance is stable at room temperature, and it is almost not reacted with acidic alkali As a kind of coating material that is hoped to be widely used in the field of anti -friction and wear, in recent years, it has received the attention of some research institutions at home and abroad. For example, U.S. General Motor Corporation reduces carbonized boron coating on the surface of the gear to reduce the teeth surface wear. Extended gear life ｡A. A. Grossman, etc. The use of boron carbide coating has the characteristics of strong absorption of neutron, and applies boron carbide coating to the nuclear industry and achieves quite good effects｡
