摘　　要：对锆合金基材表面分别进行离子渗氮和气体氮碳共渗,然后采用多弧离子镀技术在锆合金渗氮层表面制备Ti Al N涂层,并与锆合金基材表面直接制备的Ti Al N涂层进行对比,研究渗氮层对涂层结合力的影响。用立式万能摩擦磨损试验机进行摩擦磨损试验;用显微硬度计测试显微硬度;用洛氏硬度计进行压痕试验;用划痕仪测试膜基结合力。试验结果表明：锆合金经过渗氮处理其表面摩擦因数保持稳定;表面硬度和膜基结合力均有所提升,且气体氮碳共渗后的表面硬度和膜基结合力比离子渗氮略高。The Ti Al N coating was prepared by a multi-arc ion plating technology on surface of zirconium alloy substrate subjected to ion nitriding and gas nitrocarburing,respectively. Compared with the directly prepared Ti Al N coating on the surface of the zirconium alloy substrate,the effect of nitrided layer on the coating adhesion was researched. The friction and wear tests were carried out with an upright universal friction and wear tester; the microhardness was measured with a microhardness tester; the indentation test was performed with a Rockwell hardness tester; and the film-based adhesion was tested with a scratch tester. The experimental results show that the surface friction coefficient of zirconium alloy is stable on the surface nitrided,the hardness of surface and film-based bonding are both improved,and the gas nitrocarburied one is slightly higher than that of the ion nitrided one.
