摘　　要：(Ti,Al)N是20世纪80年代未期在TiN基础上发展起来的一种新型多元涂层材料。由于加入Al元素,(Ti,Al)N不但硬度、耐磨性优于TiN,而且大大改善了涂层的抗高温氧化性能。综述了Al元素在(Ti,Al)N涂层中的作用机理,以及Al含量对(Ti,Al)N涂层的晶体结构、抗高温氧化、硬度和耐磨性的影响。指出当Ti和Al的比例近似为1:1时,(Ti,Al)N涂层将获得优越的综合使用性能。(Ti,Al)N was developed in the late 1980s as a new ternary coating material based on TiN. With the addition of Al. (Ti.Al)N coating exhibits not only higher hardness and better wear resistance but also better oxidation resistance in high temperature. In this paper, how Al element affects (Ti.Al)N coating is discussed, and the effect of Al content on crystalline structure oxidation resistance in high temperature,hardness and wear resistance is summarized- Finally it is pointed out that (Ti,Al)N coating will gain superior synthesis properties when the ratio of Al to Ti in the coating is about 1 : 1.
