探讨了复合润滑体系对POM树脂摩擦磨损性能的改良效果。结果表明，以聚烯烃为主润滑剂的复合润滑体系能有效地改善POM的摩擦磨损性能，其摩擦系数下降为POM的0.60～0.70倍，Pv值提高为POM的1倍以上，耐磨损性提高了2个数量级，且POM表面的磨损在机理上属于犁切磨损、疲劳磨损及粘着磨损所引起的复合破坏过程。
The effect of compound lubricating systems on the friction and wear properties of POM resin was studied. The results indicate: the compound lubricating system composed primarily of polyolefins can improve the friction and wear properties of POM efficiently. The wearing test shows the friction coefficient is reduced to 60%～70% that of POM, the Pv value is increased to twice that of POM, the abrasion resistance is increased two order of magnitude, and the wear mechanism of POM relates to ploughing, fatigue and adhesion wear.
