采用非平衡磁控溅射技术在40Cr、9Cr18、GCr15、TC4及LY12等5种金属基体上沉积了钨掺杂含氢类金刚石(W-C:H)薄膜.采用Raman光谱仪、扫描电子显微镜、纳米硬度计及纳米划痕仪分别测试了薄膜的微结构、厚度、硬度及附着力,采用球-盘摩擦试验机及光学轮廓仪分别在干摩擦和PFPE脂润滑条件下评价了5种金属材料基体上薄膜的摩擦磨损性能.薄膜性能测试结果显示,该厚度为1μm的薄膜具有典型的类金刚石结构,硬度与弹性模量分别为11.56和128.34 GPa,附着力为645 mN;摩擦试验结果显示,在干摩擦条件下几种金属基体表面W-C:H薄膜的摩擦因数和磨损率差别比较显著,而在脂润滑条件下基体材料的影响较小;与干摩擦条件相比,脂润滑条件下薄膜的磨损可减少60％ ～75％;在干摩擦与脂润滑条件下,9Cr18与40Cr基体上的W-C:H薄膜摩擦体系分别具有最小的磨损率1.71×10-7 mm3/(N·m)及4.55×10-8 mm3/(N·m).
