摘　　要：用销盘摩擦磨损试验机研究了不同弹簧刚度下不锈钢/浸金属碳载流摩擦副间的磨损性能和受流质量。结果表明:随着弹簧刚度的增大,载流摩擦副电路中的受流质量先逐渐变好后变差,刚性时的受流质量最差;销试样(浸金属碳)的磨损性能与受流质量密切相关,受流质量越差,销试样的磨损率越大;在刚度为19N.mm-1时,受流质量最好,销试样的磨损率最低。Wear performance and current-carrying quality of the stainless steel/impregnated metallized carbon friction pairs were studied on a pin-on-disc friction and wear tester at different spring stiffnesses.The results indicate that the current-carrying quality in the friction pair circuit increased gradually first and then decreased with the increase of the spring stiffness,and the rigid current-carrying quality was the weakest.The wear performance of the pin sample with impregnated metallized carbon was closely related to the current-carrying quality.The poorer the current-carrying quality,the larger the wear rate of pin samples.The current-carrying quality was the best at the stiffness of 19 N·mm-1,while wear rate of the pin sample was the lowest.
