对等离子喷涂CoCrW涂层的微动磨损特性进行了研究。结果表明,等离子喷涂CoCrW涂层的微动磨损可分为开始、过渡和稳定三个阶段。开始阶段以粘着磨损为主;过渡阶段以氧化磨损为主;稳定阶段以疲劳磨损为主。等离子喷涂CoCrW涂层具有合适的硬度和良好的韧性,从而具有比较好的耐微动磨损性能。

The characteristics of fretting wear of plasma sprayed CoCrWcoating was investi gated. The results show that the fretting wear of plasma sprayed CoCrW coating can be divided into three stages, which are respectively initial, transi ent and steady stages. The main fretting wear mechanism is respectively adhesion , oxidation and fatigue wear. The high fretting wear resistance of plasma sprayed CoCrW coating results from its moderate hardness and excellent toughness.
