Metastable PVD films have been developed by incorporating second metals to binary nitride films in aims a gaining excellent mechanical and tribological properties. The cathodic arc method is a specialized method in creating metastable ternary films which cannot be synthesized under stable thermodynamic conditions. In this series of study, 2004-2006, the maximum hardness of ceramics nitride films was investigated based on the phase transition analyzed by X-ray diffraction and scanning and transmission electron microscopy.Ternary nitride films had higher microhardness than the binaries and had their own maximum hardness at certain values. The crystal structures of Ti_<1-x>Al_xN changed from the NaCl-type to Wurtzite-type at the X=0.6, while the structures of Ti_<1-x>Cr_xN and Ti_<1-x>Zr_xN retained the NaCl-type for all X values. The maximum microhardness of Cr_<1-x>Al_xN and Zr_<1-x>Al_xN were obtained at phase boundary, where films had had some special microstructure with the mixture with crystal and amorphous. Addition of Cr atoms to (Ti, Al) N films expanded maximum Al solubility up to 73 at.% without hexagonal phase segregation. The cubic Ti_xCr_yAl_zN films obtained by thermal annealing were investigated with respect to phase transition, lattice parameter and microhardness. They were kept cubic type even up to 800℃. The lattice parameter of films at decreased by 0.5% compared with to that of room temperature. Finally, cubic phase was partially transformed into hexagonal phase through the thermal diffusion process over 900℃, which decreased its microhardness.

亚稳态 PVD ​​薄膜是通过将第二种金属掺入二元氮化物薄膜而开发的，目的是获得优异的机械和摩擦学性能。阴极电弧法是一种在稳定的热力学条件下无法合成的亚稳态三元薄膜的专用方法。研究，2004-2006年，基于X射线衍射和扫描透射电子分析的相变，研究了陶瓷氮化膜的最大硬度三元氮化物薄膜具有比二元氮化物更高的显微硬度，并且在一定值下具有各自的最大硬度。当X=0.6时，Ti_<1-x>Al_xN的晶体结构从NaCl型转变为纤锌矿型。 Ti_<1-x>Cr_xN 和 Ti_<1-x>Zr_xN 的结构在所有 X 值下均保留了 NaCl 型。在相界处获得了Cr_<1-x>Al_xN和Zr_<1-x>Al_xN，薄膜具有晶态与非晶态混合的特殊微观结构。研究了热退火获得的立方Ti_xCr_yAl_zN薄膜的相变、晶格参数和Al溶解度高达73 at.%。其显微硬度在800℃时仍保持立方型，薄膜的晶格参数比室温降低了0.5%，最后在900℃以上的热扩散过程中，部分立方相转变为六方相。其显微硬度降低。
