The use of boron nitride in the coating industry is based on its lubricating properties, especially at high temperatures. The main applications are as follows: boron nitride coating and boron nitride release agent.
Boron nitride has a very low coefficient of friction, excellent self-lubricating properties, and good self-lubricating ability even at high temperatures. Soft lubricating component. The coating of boron nitride should be sprayed by gas-stabilized plasma spraying, supersonic flame spraying and explosive spraying technology. Hexagonal boron nitride is used as a soft component of high temperature sealing coatings for aero-engines, high temperature lubrication and antifriction coatings, electrical insulating coatings, neutron absorption coatings, etc., such as high frequency and plasma arc insulators, anti-neutron Radiation coatings, high temperature abradable coatings, etc.
Metals, as well as ceramics and graphite, can be coated with BN coatings, giving them good lubricity and anti-stick (mold release) properties. In addition, the chemical reaction between the substrate and the melt can be reduced or prevented after the coating has been applied, thereby extending its service life.
