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.
