【摘要】 以全配方矿物基50CC级柴油机油和SF/15W-40型汽油机油作为基础润滑油,采用微动、滑动磨损试验机考察了有机钼复合添加剂对45钢/GCr15轴承钢摩擦副的高温微动、滑动磨损性能的影响,结果表明:有机钼添加剂通过分解、吸附和摩擦化学反应,在金属表面形成了吸附的磷酸盐和含FeS、MoS₂的化学反应膜共同组成的复合表面保护膜,从而有效地改善#45钢/GCr15轴承钢摩擦副的高温微动、滑动磨损性能,并具有明显的减摩效果。更多还原

【Abstract】 The high temperature fretting and sliding tribological behavior of 45^# Steel and GCrl5 tribopairs were studied under the lubrication of a fully formulated petroleum based engin nil 50CC and SF/15W-40 containing organic molybdenum compound lubricating additive. The result shows: organic molybdenum compound additive can effectively improve the high temperature fretting and sliding wear properties to 45^# steel/GCr15 tribopairs, and it also have certain friction resistance property. XPS analysis shows: the tribochemical films are mainly composed of FeS and MoS₂.更多还原
