Wear Behavior of Cu-Based Composite under Different Electrical Currents

Abstract:

Cu-La₂O₃ composite was fabricated by internal oxidation method using powder metallurgy. Its sliding behavior was studied under various electrical currents and applied loads. The worn surfaces of Cu-La₂O₃ composite were characterized using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) to probe the wear mechanisms. The results indicated that applied load has a significant effect on the wear rate of the Cu-La₂O₃ composite pins. The wear rate displayed the minimum value at the load of 50N during electrical sliding processes.
