How much do you know about boron nitride coating? Follow the editor of Best Blue white BN boron nitride coating to have a simple understanding!

A preparation method of cubic boron nitride coating, which is to prepare the coating on the high-speed steel substrate by the method of radio frequency magnetron sputtering. By adding a small amount of Fe to the sintered BN target material, it can be A small amount of iron or iron nitride phase is formed in the coating or between the cubic boron nitride and the substrate, thereby reducing the thermal expansion coefficient of the cubic boron nitride and the high-speed steel substrate material, thereby avoiding the burst and peeling of the coating and the substrate. Improve the compactness and bonding force of the coating and the substrate; and through reasonable parameter control, a uniform and thick cubic boron nitride coating can be prepared.
In summary, the editor of Best Blue white BN boron nitride coating tells: a brief introduction to the little knowledge about boron nitride coating.
