Worn Surface

The sliding wear behavior of Cu-Ag alloy in Cu cladding Al contact wire against 45# steel or bronze block was tested, then surface morphology was investigated in different load and velocity. The results indicated that the worn surface had plastic deformation and many clear furrows and cutting traces along the sliding direction. There were black oxide of copper on the worn surface. The oxide was both abrasive and lubrication. The mechanisms transformed from abrasive attrition into adhesive wear. Spalling pits and adhesive blocks with bronze friction were significantly bigger than that of steel, and the mechanisms was adhesive wear.
