所谓磨损是指一固体的机械作用从而磨掉另一固体的表面物质。如货币因人手不断接触而磨损,铅笔因书写而磨损,铁轨因车轮不断滚动而受损,只有生物的关节因能再生才不会因磨损而受到永久性的损坏。优质润滑剂能在滑动面上形成一层固态厚膜,从而降低了摩擦系数,也有效地减少了磨损。润滑剂的使用古已有之。现代润滑技术的努力方向是继续减少磨损及设计长期 The so-called wear refers to a solid mechanical action to wear away the surface of another solid material. If the currency is worn by constant contact with the hand, the pencil is worn due to writing, the track is damaged by the rolling of the wheel, and only the joint of the living creature is regenerated so as not to be permanently damaged by wear and tear. High quality lubricants form a solid thick film on the sliding surface, reducing the coefficient of friction and reducing wear. The use of lubricants has always existed. The direction of modern lubrication technology is to continue to reduce wear and long-term design
