摘要：
In the present study, the friction and wear behaviors of copper-graphite composite against GCr15 steel in high-speed sliding with current were investigated. The worn surfaces and wear debris were analyzed by scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS), and the wear mechanisms were discussed. It shows that the current plays an important role in the high-speed dry sliding of copper-graphite composite against GCr15 steel. With increasing current, the friction coefficient decreases, and the wear rate increases. The wear mechanisms of the copper-graphite composite are main abrasion and fatigue without current, and that of with current are main fatigue, arc ablation.
