对工业上重要的轴承材料ThordonXL聚合物和铅锡合金LgSn80相对于等离子喷涂Al2O3涂层的摩擦磨损性能的研究，结果表明，ThordonXL聚合物在干摩擦低负荷和有润滑较大负荷范围内有本文研究材料最好的耐磨性。而铅锡合金LgSn80在于摩擦重载荷及有润滑重载荷下均有较好的耐磨性能。在速度为1m／s，负荷为45．3N时，ThordonXL聚合物的干摩擦系数最低（0．44），而LgSn80合金的干摩擦系数为0．55~0．60。本文分析了有关的磨损机理。ThordonXL聚合物的磨损过程主要是剪切断裂，而LgSn80合金则是磨蚀磨损。
Study on the friction and wear properties of ThordonXL polymer and Pb-Sn alloy relative to the plasma-sprayed Al2O3 coating showed that the ThordonXL polymer has the properties of low friction load and lubrication under dry load Study materials for the best wear resistance. The lead-tin alloy LgSn80 is under heavy friction load and under heavy lubrication have a good wear resistance. ThordonXL polymer had the lowest dry friction coefficient (0.44) at 1 m / s and a load of 45.3N, whereas the dry friction coefficient of LgSn80 alloy was 0.55-0.60. This article analyzes the related wear mechanisms. ThordonXL polymer wear process is mainly shear fracture, and LgSn80 alloy is abrasive wear.
