摘要	The nanocomposite multilayers, composed by typical nitride ceramic (AlN and TiN), have been developed for variety of application for its excellent properties such as structure stability and high hardness as well as low friction coefficient. By adding an appropriate amount of soft metal, the mechanical performance of the film can be significantly improved including intensity, tenacity and friction coefficient, but microstructure and hardness will be greatly influenced. In this work, AlN/TiN-Cu nanocomposite multilayers combining AlN with composite layer formed by adding soft phase metal Cu into hard TiN phase were prepared by multi-arc ion plating equipment. The microstructure and phase composition of the films were characterized by FESEM, HRTEM and XRD respectively. The hardness and the bond strength of the films were detected by Vickers hardness test and scratch method. The effects of Cu on microstructure and mechanical properties of AlN/TiN-Cu nanocomposite multilayers were investigated. The results show that the microstructure of the films was affected by the doping of Cu. The average grain size of the films reduced with the increase of Cu content. The hardness of films increased after the dropping of Cu. However, the critical loads of the films with different types have different changing trends. The critical load of the nanocomposite monolayers increased while that of the nanocomposite multilayers decreased.
