Experiments were conducted under a dry gross fretting regime. Steel discs were put in contact with ceramic balls. Before tribological tests, discs were subjected to ball burnishing with different pressures. Due to ball burnishing, a decrease in surface amplitude and an increase in microhardness occurred. Ball burnishing caused decreases in the friction force and volumetric wear of up to 45% in comparison to sliding pairs containing milled discs. The friction force and volumetric wear were higher for a higher roughness of disc.
实验是在干式宏观微动磨损工况下进行的。将钢盘与陶瓷球接触。在摩擦学测试之前,对钢盘施加不同压力进行滚珠研磨。由于滚珠研磨,表面振幅降低,显微硬度增加。与含有研磨盘的滑动副相比,滚珠研磨使摩擦力和体积磨损降低了45%。盘的粗糙度越高,摩擦力和体积磨损就越大。
