摘　　要：对等离子喷涂的四种不同MoS2含量的Ni/MoS2涂层的干滑动摩擦磨损性能和机制进行了试验和探讨。结果表明,MoS2的质量分数为30%时磨损率最小;磨损机制主要为磨粒磨损;较大载荷下、MoS2较多时导致其磨损率急剧增大的原因,与润滑膜破坏引起的疲劳磨损和粘着磨损有关。The dry sliding wear and friction behavior and mechanism of four kind of Ni/MoS_2 coating with different MoS_2 content by plasma-spraying were tested and investigated. The results show that the wear rate of 30%MoS_2 coating is smallest; the abrasive wearis major wear mechanism; the destruction of lubricating film with a bigger loador more MoS_2 content causes rapid increases of wear rate, produces the fatigue wear and the adherence wear.
