摘　　要：针对TiAlN涂层刀具的耐磨性,以镍铬合金为摩擦副,利用MS-W6000型高温摩擦试验机研究了劈裂电弧(MDT)和传统电弧离子镀两种涂层工艺制备的TiAlN涂层的摩擦磨损性能。试验结果表明:在室温下,传统电弧离子镀涂层的摩擦性能较差;在高温下,两种涂层的摩擦性能相近,但MDT涂层的稳定性更好。To study the wear resistance of TiAlN coated tools,the Ni-Cr alloy was used as the friction pair,the friction and wear properties of TiAlN coating prepared by two kinds of coating technology of split arc（MDT） and conventional arc ion plating were studied by MS-W6000 high temperature friction tester. The experimental results show that the tribological properties of conventional arc ion plating coating are worse at room temperature and the friction properties of these two kinds of coatings are similar at high temperature, but the stability of MDT coating is better.
