摘　　要：氮化物金属陶瓷涂层由于具有高的硬度和化学稳定性，成为近年来防护涂层的研究热点。利用脉冲偏压电弧离子镀技术在压气机叶片用1Cr11Ni2W2MoV热强不锈钢基体上沉积了（Ti0．5Al0．5）N、（Ti0．45Al0．45Cr0．1）N和（Ti0．35Al0．35Cr0．3）N亚稳金属陶瓷涂层，研究了涂层的组织、结构和900℃下的氧化行为。3种涂层均为B1NaCl结构，（220）为主要的织构取向。在900℃静态空气中（Ti0．5Al0．5）N氧化严重，添加Cr的涂层表现出优异的抗氧化性。In this study, composite metastable （Ti0.5Al0.5）N, （Ti0.5Al0.5）N,（Ti0.45Al0.45Cr0.1）N and （Ti0.35Al0.35Cr0.3）N coatings were respectively deposited on a wrought martensite steel 1Cr11Ni2W2MoV for aero-engine compressor blades by arc ion plating with a pulse bias. All the coatings have B1NaCl phase and dense structures. The introduction of chromium into （Ti0.5Al0.5）N gave rise to a minute shrinkage of crystal lattice and a decrease of crystal size. Oxidation-resistance at 900℃ in air was investigated and the results showed that the incorporation of chromium in to the coatings dramastically improved the oxidation-resistance of the coatings and （Ti0.35Al0.35Cr0.3）N coating presented a more excellent oxidation-resistance than （Ti0.45Al0.45Cr0.1）N coating.
