摘　　要：采用化学气相沉积和物理气相沉积工艺,分别选用高铝钛及TiC+Ti(C,N)+TiN复合的金属陶瓷在滑动轴承表面制备金属陶瓷膜层。采用金相显微镜、体视显微镜和显微硬度计对不同金属陶瓷膜的表面形貌、组织结构及厚度进行测量和观察,并在MMW-1型万能摩擦磨损试验机对涂层材料进行摩擦磨损试验,通过测量磨损量与摩擦因数随时间的变化规律,观察摩擦副表面磨损形貌,分析了不同陶瓷膜层的耐磨性和摩擦磨损机理。结果表明,涂镀复合陶瓷膜(TiC/Ti(C,N)/TiN)的销试件硬度高、磨损极其轻微、表面均匀且光滑,复合陶瓷膜(淬火)更适用于牙轮钻头滑动轴承表面涂层材料。High Al-Ti membrane and composite ceramic membrane of TiC,Ti（ C,N） and TiN on the surface of rock bit bearings were prepared by chemical vapor deposition and physical vapor deposition. Surface morphology,the microstructure and the thickness of these different metal-ceramics films were observed by using optical microscope,stereomicroscope and microhardness tester respectively. Friction and wear experiment were conducted on MMW-1 universal testing friction and wear machine. surface morphology of the friction pair were observed by recording the wear loss and friction coefficient variation with time,and the wear resistance and the friction and wear mechanism were analysed. The results show that pin specimen that coats the composite ceramic membrane of TiC,Ti（ C,N） and TiN owns high hardness and it＇s wear loss is the minimum,the surface of the pin specimen is smooth and uniform. So,the quenched composite ceramic membrane of the TiC,Ti（ C,N） and TiN is more suitable for the surface coating material of rock bit bearings.
