Research of Cii-xMxN's (M=AI,V,Ti,etc.,x=0.5) coating valence electron structure calculation and wear-resisting performance

摘要

Based on empirical electron theory of solid and molecule (EET, Empirical Electron Theory of Solids and Molecules) ,this paper calculated the Crl - xMxN molecular coating's valence electron structure of the phase space and the valence electron structure of coating matrix phase out of phase interface. By analysing microscopic valence electron structure, we discussed the alloy elements' influence on this series of coatings' resistance. And we found that V elements can significantly increase the metal chromium nitride's were resistance , element Ti takes the second place, element Al also has some effect.
