用反应磁控溅射方法,在不锈钢表面沉积Ti-Si-N薄膜.用原子力显微镜观察薄膜的表面形貌,Ti-Si-N颗粒尺寸小于0.1 μm,用亚微压入仪测试薄膜硬度,当硅的摩尔分数为9.6%时,薄膜硬度出现最大值47 GPa.球-盘式摩擦磨损结果表明,Ti-Si-N薄膜的耐磨性能明显优于TiN薄膜,加入少量硅元素后,TiN薄膜的抗磨损性能有显著提高,但Ti-Si-N薄膜的室温摩擦系数较高(0.6～0.8),高温下摩擦系数也仅轻微降低(550℃,0.5～0.6).由于Ti-Si-N薄膜的摩擦系数可能与磨损中氧化物生成量的增加有关,常温下Ti-Si-N薄膜的摩擦系数随硅摩尔分数的增加而增大,而高温下Ti-Si-N薄膜的摩擦系数随硅含量上升而降低.
