实验结果表明：本文中几种烧结钢的磨损机制均是由磨粒磨损、粘着磨损、和疲劳磨损共同作用的，且以磨粒磨损为主；在烧结态下，复合添加合金元素镍、钼的烧结钢的耐磨性能最好，这是因为生成了大量的硬质相贝氏体；而淬火、低温回火态下，则复合添加钼、钨的烧结钢的耐磨性能最好，这是因为热处理态下添加钼、钨的烧结钢的硬度最高。 |

研究结果表明，由于增强相具有抵抗磨损的作用，使得复合材料具有很高的耐磨性；在干摩擦条件下复合材料的磨损主要是粘着、显微切削以及复合相脱落、碎裂等多种机制综合作用的结果。 |
| 7. | ( 2 ) it is found that distilled water as lubricant can markedly reduce the accumulation of friction heat and temperature rise on the frictional surfaces of polymer . so the heat fatigue and adhesive wear decrease . moreover , a lubricating film forms on the interface between the counterpart and polymer when distilled water acts as polar lubricant
( 2 )润滑剂水的存在，可大幅度降低聚合物磨损表面的摩擦热积累及温升，从而减少了基体的热疲劳磨损和粘着磨损，同时，水作为一种极性润滑剂，在摩擦界面上能形成一层润滑膜，对摩擦表面起了一定的隔离作用。 |

在无润滑条件下，通过对磨痕形貌的观察，认为铁基合金的磨损机理主要是粘着磨损和磨粒磨损，同时伴随有一定程度的氧化磨损；加入sic后主要是磨粒磨损和脆性剥落，且sic越多材料的脆性剥落越严重。 |
