大气条件下,研究不同强度的直流稳恒磁场对45钢干滑动摩擦磨损性能的影响.结果表明:与无磁场条件下相比,材料的摩擦系数降低,磨损量明显减少,磨损表面光滑,磨屑细化.微观分析表明,45钢在磁场条件下磨损后,表面生成更多的氧,认为氧化磨损及磨屑的润滑作用是磁场降低摩擦系数、减轻磨损的主要原因.

The influence of D C constant magnetic field on tribological behaviour of 45 steel pin against disc in atmosphere was investigated. The results indicated that the wear loss decreased and friction co-efficient went down, the worn surfaces were smooth and debris were fine obviously with a magnetic field. Microscopic analysis by SEM and EDS showed that more oxide-protective film formed on worn surface in the presence of a magnetic field. Oxidative wear mechanism and lubricated effect of debris were stated, which played an important role during the friction and wear.
