| 摘 要： | 本文中考察了铝自配副在干摩擦和微量离子液体润滑条件下的载流摩擦学性能.在干摩擦条件下,铝自配副因黏着极易发生卡咬.而微量的离子液体L-P106就可有效润滑铝自配副,摩擦系数可低至0.1左右.无论载流与否,润滑状态均为边界润滑.与无载流条件相比,载流时铝自配副的摩擦系数稍有增大,且在高速(0.79 m/s及以上)磨损由中等程度的磨损转化为严重磨损.电流会导致电侵蚀磨损,从而使磨损加剧.

| Abstract: | The tribological behaviors of self-mated Al under electrical contact in both dry sliding and ionic liquid lubricated conditions were investigated. In dry sliding,seizure of self-mated Al was observed due to strong adhesion. By using minimal quantity ionic liquid L-P106 in the sliding contact,the friction coefficient of self-mated Al was as low as 0.1. Results indicate that the lubricating regime is boundary lubrication with or without current. The friction coefficient of self-mated Al under current-carrying was higher than that without current. The transition from moderate wear to severe wear at higher speeds (>0.79 m/s) was observed. Erosive wear induced by current aggravated the wear of self-mated Al. |
