EDAX and talysurf. There were four wear regimes for KRF/GCI, during the starting friction period abrasion was dominant, when the process of the formation and break of transfer layers was balanced the main wear mechanisms were adhesion and fatigue, mild melt wear was found at higher temperature. For KRF/MMC, the dominant wear mechanisms were ploughing and microcuting during the running-in, when transfer layer formed, the film-film adhesion at the interface became dominant and mild melt wear occurred also at high temperature.

对于KRF/GCI，在摩擦的起始阶段主要是二体磨粒磨损，当表面转移膜的形成与破坏形成动态平衡时，粘着磨损和疲劳磨损是主要磨损机理，摩擦表面温度较高时，产生严重的粘着磨损和轻微的熔融磨损；而KRF/MMC在跑合过程中，SiCp对较软材料的犁削、微切削是主要摩擦磨损机理，转移膜形成后，表面的膜—膜粘着则为主要摩擦磨损机理，高温下也会发生轻微的熔融。
