Tribo-Electric Behaviors of Copper Under Dry Sliding Against Cu-Cr Alloys

The tribological and electrical conduction behaviors of copper under dry sliding against copper-chromium alloys were investigated on the basis of simulation tests. The experimental results show that electrical current and trbological parameters have combined effects on both electrical conduction ability and trological properties. High sliding velocity and electrical current density deteriorate both the tribological and electrical conduction properties in tribo-electrical sliding system. In the end, Worn surface analysis suggests frictional and electrical resistance heating, electrical arc spoiling are the main factors to influence the tribological and electrical conduction properties.
