Cubic boron nitride coatings are under development for a variety of applications but stabilization of the pure CBN form and adhesion of films deposited by PVD and ion - based methods have been difficult. An alternate two - stage process comprising of ESC (electrostatic spray coating) and CVI (chemical vapor infiltration) has been developed for depositing CBN - TiN composite coatings for wear related applications. The process optimization yields fully dense films of CBN particles evenly dispersed in a continuous TiN matrix. Metal cutting tests (turning – 4340 steel), using CBN - TiN composite coating thus developed, have shown an increase in tool life of three to seven times, depending on machining parameters, in comparison with CVD deposited TiN films.
