摘　　要：采用中频磁控溅射技术及多弧离子镀相结合的复合镀膜工艺,在硬质合金YT14基体上制备了MoS2-Zr复合薄膜。采用扫描电子显微镜(SEM)观察了MoS2-Zr复合薄膜表面及截面形貌,利用多功能材料表面性能试验仪测试了薄膜的厚度、结合力,利用显微硬度计测试薄膜的显微硬度,在高速环块磨损试验机进行了摩擦磨损试验,并分析了薄膜的摩擦磨损机制。结果表明:制备的MoS2-Zr复合薄膜结构致密,薄膜的厚度、结合力、显微硬度等性能参数明显优于MoS2薄膜,摩擦磨损性能有较大改善。薄膜的摩擦磨损过程主要是薄膜的剥落和转移的过程,复合薄膜由于结合力和硬度的提高,能够延缓薄膜的剥落及转移,降低薄膜的磨损率,提高薄膜的摩擦磨损特性,延长薄膜的作用时间。The pure MoS2 coatings and MoS2-Zr composite coatings were prepared on the surface of cemented carbides YT14 with complex deposited process of medium-frequency magnetron sputtering and multi-arc ion plating.The surface and cross-section of flim were observed by SEM,the thickness,adhesion strength and hardness were tested by material surface performance tester and microhardness tester,and the tribological performance was determined by high speed ring-on-block wear tester.The experimental results indicate tha...
