摘要
为得到摩擦性能良好的导电涂层,用磁控溅射法制备了3种碳/铜复合涂层,利用载流摩擦磨损试验机分别测试了导电润滑脂润滑下不同电压时各涂层的载流摩擦学性能,通过扫描电镜(SEM)和X射线光电子能谱仪(XPS)观察并分析了磨痕表面形貌及主要元素化学状态。结果表明:磁控溅射碳/铜复合涂层具有优良的减摩抗磨能力和较好的导电性能,制备的涂层2中(制备工艺参数为C靶功率1000 W、Cu靶功率200 W)碳和铜的比例最合适;在载流摩擦过程中,磁控溅射碳/铜复合涂层中形成了石墨化碳膜和以氧化物为主的摩擦化学保护膜。
In order to prepared the conductive coating with tribological properties,three carbon/copper composite coatings were prepared by magnetron sputtering.The current-carrying tribological properties of each coating lubricated with electrically conductive grease under different voltages were tested using a current-carrying friction and wear tester.Moreover,scanning electron microscope(SEM)and X-ray photoelectron spectroscopy(XPS)were used to observe and analyze the surface morphology of the wear scar and the chemical state of the main elements.Results showed that the magnetron sputtering carbon/copper composite coatings possessed excellent friction and wear resistance and good electrical conductivity,and the ratio of carbon to copper in coating 2 was the most appropriate.During the current-carrying friction process,the magnetron sputtering graphitized carbon film and tribo-chemical protective film dominated by oxides were formed in the magnetron sputtered carbon shot/copper composite coatings.
