The material damage during triboelectric process could obviously affect the life of currentcarrying frictional pairs. The triboelectric behaviors of pure copper were investigated by using pure copper as pin samples and the QCr05 as disk sample. In addition to the main wear behaviors in normal dry sliding, the results reveal that the electricity results in some special wear behaviors during currentcarrying sliding. For instance, the surface temperature is increased by 5.6-7.2 times at the load of 570 N, the sliding speed of 10 m/s, and the electricity from 0 to 60 A, the surface becomes seriously rough,and there is an inhomogeneous plastic layer on the subsurface, the thickness of which is about 180 μm at the load of 70 N,the sliding speed of 20 m/s, and the electricity of 60 A.The electricity directly causes the material damage, which mainly contains sputtering and melting.
