Cubic Boron Nitride

General Information:

c-BN coatings are extremely difficult to fabricate due to the tendency to sublime at high temperature. NTST has developed the unique capability to fabricate c-BN coatings using a modified plasma spray process.

The crystal structure of c-BN is analogous to diamond. This material has hardness slightly lower than diamond but its thermal and chemical stability is superior to diamond. Because of this better stability, c-BN surpasses diamond in mechanical applications, such as machining. The benefits of c-BN include intermediate density (i.e., 1.5 times that of h-BN), low coefficient of thermal expansion, and high thermal conductivity (i.e. the highest of all electric insulators). c-BN is a wide semiconductor, and possesses remarkable chemical and thermal stabilities.

c-BN is one of the hardest materials next to diamond, making it extremely valuable for wear applications. It offers high hardness and high resistance to fracture, erosion, and abrasion, and high heat and chemical resistance.

Extensive materials characterization is currently being conducted for this material. When this is accomplished this page will be updated to reflect this. Currently, there is a preliminary downloadable brochures for this coating at thr bottom of the home page.
