摘要
采用非平衡磁控溅射沉积技术制备MoS2-Ti复合薄膜,研究了工件台转速对薄膜的结构和性能的影响。利用XRF和XRD分析薄膜的成分和晶相结构,用CSEM薄膜综合性能测试仪测试薄膜的硬度和与基底间的附着力,用球-盘摩擦试验机和真空环模系统评价薄膜的真空摩擦磨损性能。结果表明:提高工件台转速改善了掺杂金属Ti在薄膜中的分布均匀性,起到了细化晶粒尺寸,使薄膜组织结构致密性加强的效果。工件台转速变化不影响薄膜成分,薄膜的晶相从明显的(002)基面优势取向向准晶态转变;薄膜的硬度、与基底间的附着力都随工件台转速的提高而增大;薄膜在真空环境中的减摩作用与工件台转速无关,摩擦因数平均值为0.02,波动范围为0.01～0.04,薄膜耐磨寿命随工件台转速提高而延长。
