摘　　要：采用射频等离子体增强化学气相沉积(RF-PECVD)方法在316L钢衬底上沉积类金刚石薄膜,比较类金刚石薄膜在油和水润滑下分别与氮化硅和316L钢材料对磨的摩擦和磨损性能。实验结果显示:类金刚石/氮化硅摩擦对偶在合成油的润滑下具有最低的摩擦系数和磨损率;在空气中的摩擦系数和磨损量相比,类金刚石/氮化硅摩擦对偶添加合成油减小了45.8%的摩擦系数和94.4的磨损量。添加蒸馏水可以有效减小类金刚石薄膜的摩擦系数和磨损量,与空气中的摩擦系数相比,类金刚石/氮化硅摩擦对偶和类金刚石/316L钢摩擦对偶在蒸馏水润滑下的摩擦系数分别减小了44.8%和51.3%。在对磨损要求较为宽松的应用场合,蒸馏水可以为类金刚石/氮化硅摩擦对偶和类金刚石/316L钢摩擦对偶提供足够的润滑。The aim of this study was to compare the performance of DLC film on 316L plates against Si3N4 and 316L steel balls,in contact with in air(24% RH),synthetic oil and distilled water.The results show that there is the lowest friction coefficient and wear volume in the DLC/Si3N4 pair with synthetic oil; adding oil decreases friction coefficient by 45.8% and wear volume by 94.4% in comparison with their friction coefficients and wear volume in air(24% RH).Adding distilled water decreases the friction coefficient by 44.8% in the DLC/Si3N4 pair,51.3% in the DLC/316L,in comparison with their respective friction coefficients in air(24% RH).
