Abstract

CrxAlyBzN films were synthesized by the cathodic arc method, using CrxAlyBz alloy cathode with differing z values from 0 to 0.10 and investigated with respect to crystal structures, lattice parameters and microhardness. The microhardness of CrxAlyBzN increased from 27 (z = 0) to 33 GPa (z = 0.10). The lattice parameters of CrxAlyBzN decreased from 0.413 (z = 0) to 0.410 nm (z = 0.10), keeping the cubic structure. The columnar structure of CrxAlyBzN disappeared and grain size decreased with incorporations of B atoms. In this study, CrxAlyBzN films were characterized by X-ray and electron microscopy analysis and the relationship between microstructure and microhardness was discussed as a function of B contents.
