摘要

为了研究导电润滑脂对碳滑板/接触丝系统载流摩擦性能的影响，进行了不同润滑条件和干摩擦条件下的对比试验。与干燥条件相比，润滑脂润滑对摩擦和磨损性能有显著改善，摩擦系数和碳滑板磨损率分别降低了31%-40%和58%-82%。导电润滑脂的温升特性与其电导率呈正相关。此外，润滑脂的应用扩大了碳滑板与接触丝之间的接触面积，改善了界面条件，降低了异常磨损风险。

The influence of different grease lubrications on the current-carrying wear performance of carbon skateboards/contact wires

To investigate the effects of conductive greases on the current-carrying friction behavior of carbon skateboard/contact wire system, comparative tests were conducted under various lubrication conditions and dry friction. Significant improvements in friction and wear performance were revealed, with coefficients of friction and carbon skateboard wear rates reduced by 31%–40% and 58%–82%, respectively, under grease lubrication compared to dry conditions. The temperature rise characteristics of conductive greases correlate positively with their electrical conductivities. Additionally, the contact area between carbon skateboard and contact wire was expanded and sustained by grease application, enhancing interfacial conditions and mitigating abnormal wear risks.

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
