在干摩擦状态下,对用二硫化钼、石墨填充至聚四氟已烯中所组成的复合材料进行了摩擦磨损特性的研究.通过试验分析得知填料减磨的主要机理,是由于在摩擦表面上存在转移膜以及填料具有的自润滑特性,使得对磨时与纯聚四氟已烯相比摩擦系数降低、耐磨性提高
Under the condition of dry friction, the friction and wear properties of the composites composed of polytetrafluoro-hexene filled with molybdenum disulfide and graphite were studied.Analysis of the main mechanism of the friction-reducing of fillers was made by the friction The presence of the transfer film on the surface and the self-lubricating properties of the filler make the friction coefficient lower and the abrasion resistance higher than that of the pure polytetrafluoroethylene by the grinding
