摘　　要：采用M-200型摩擦磨损试验机,对比研究了几种填充PTFE复合材料与石英玻璃对磨时,在水润滑、低速、较高载荷条件下的摩擦学特性。结果表明:在水润滑条件下,MoS2/PTFE复合材料与石英玻璃对磨时的摩擦系数可低于0.005,表现出超润滑摩擦特性,而且具有稳定的摩擦系数和很低的磨损率。石英玻璃所具有的优良表面特性和优异的亲水性是实现超润滑的关键。当添加高硬添料时,石英玻璃表面容易受到破坏,导致摩擦学性能下降。The tribological characteristics of MoS2 /PTFE composite versus quarty glass under water lubrication, low speed and higher load were in vestigaled on the type M-200 friction and wear tester. It was found that the friction factor between MoS2 /PTFE composite and quarty glass is lower than 0. 005 under water lubrication, demonstrating the ultra lubrication behavior with stable friction factor and low wear rate. The extreme low surface roughness and excellent water affinity of the quarty glass surface are the key factors to renlize the ultra lubrication. Addition of hard filler into the friction material tends to destroy the quarty glass surface,results in deterioration of tribological performance.
