为了获得具有良好导电性和耐磨性的新型滑动电接触材料，采用非平衡磁控溅射技术制备了TV MoS 2、Pb/MoS 2和MoS 2涂层。结果表明，电流（0.5A）下涂层与铜球和铝球滑动时的摩擦系数下降，主要原因是在电流作用下，涂层与金属表面粘附的物质增多，转移膜变得致密。由于接触界面粗糙度的增加和磨料磨损性能的增强，有电流的涂层的磨损率大于无电流的涂层。
To obtain novel sliding electrical contact materials with good electrical conductivity and wear resistance, TV MoS2, Pb/MoS2 and MoS2 coatings were deposited by unbalanced magnetron sputtering system. The results showed that the friction coefficients of the coatings with current (0.5 A) sliding against Cu and Al balls decreased, and the primary cause was that more materials adhered from the coatings to the metal surfaces and the transfer films became denser under the action of the current. Due to the increase in the roughness and strengthening of the abrasive properties on the contact interfaces, the wear rates of the coatings with current were larger than those without current.
