摩擦副两对偶表面作滚动或滚滑复合运动时，由于交变接触应力的作用，使表面材料疲劳断裂而形成点蚀或剥落的现象，称为表面疲劳磨损（或接触疲劳磨损）。
涂层表面的磨损机制主要为开始以黏着磨损和氧化磨损为主，逐步过渡到以表面疲劳磨损和磨粒磨损为主。
The wear mechanisms of the high temperature of the coatings are mounting and oxidation early, fatigue and abrasive afterwards.
齿轮表面的疲劳磨损是齿轮故障的主要形式之一。
Fatigue wear on the surface of gear is one of the main kinds of failure of the gear.
表面复合材料的磨损机理主要是反复塑性变形和疲劳剥落。
The wear mechanism of composites is mainly repeating toughness deform and fatigue flaking off.
