The purpose of this investigation is to analyse microscopic wear mechanism of ceramic coatings, based on friction tests in the CCD microscope. Following results were obtained ;(1) Microscopic wear modes of ceramic coatings can be classified into following three modes ;1) spalling of coating film at initial sliding passage2) spalling of coating film after certain sliding passages3) wear of coating film(2) Wear modes of coating film can be classified into following two modes ;1) flake formation : This is the severest wear mode of ceramics by macroscopic surface crack propagation.2) powder formation : This is caused by microscopic surface crack propagation.

本文通过在CCD显微镜下的摩擦试验，分析了陶瓷涂层的微观磨损机理。研究结果表明：（1）陶瓷涂层的微观磨损模式可分为3种：1）涂层在滑动初期的剥落; 2）涂层在一定滑动道次后的剥落; 3）涂层的磨损;这是宏观表面裂纹扩展导致的最常见的磨损模式。2）粉末形成：这是由微观表面裂纹扩展引起的。
