采用真空浸渍抑弧油(以下简称浸油)工艺制备受电弓滑板用炭/炭(C/C)复合材料，并对未浸油/浸油的C/C复合材料进行载流磨损性能测试，采用SEM对C/C复合材料断面、磨损面及其磨屑的微结构进行表征。结果表明：浸油可降低C/C复合材料的摩擦因数且其稳定性优于未浸油C/C复合材料；载流摩擦条件下，抑弧油可提高C/C复合材料的载流磨损性能，浸油C/C复合材料的磨损率约为未浸油C/C复合材料的1/3。未浸油C/C复合材料/铜的磨损机理主要是电火花烧蚀、氧化磨损和剥层磨损的综合作用；浸油 C/C 复合材料/铜的磨损机理主要是轻度冲击磨损、剥层磨损和轻微的电弧侵蚀磨损。

The carbon/carbon composites were vacuum impregnated by arc restraining oil, and the current-carrying wear characteristics of carbon/carbon composites were tested. The microstructures of the cross section, worn surface and the debris of carbon/carbon composites were charactered by SEM. The results show that, compared with the carbon/carbon composites without impregnation, the carbon/carbon composite impregnated by arc restraining oil has a lower and more steady friction coefficient, and the wear rate is one-third of which without impregnation when the current density is 375A/cm2. The wear mechanism of the carbon/carbon composite without impregnation is mainly arc erosion wear, oxidation wear and delamination wear. And the wear mechanism of the carbon/carbon composite with vacuum- impregnation is mild impact wear and delamination wear, the arc erosion wear is weakened.
