چکیده انگلیسی
Dry sliding wear tests on 5 wt.% copper oxide doped yttria stabilized zirconia polycrystals (CuO-TZP) composite have been performed against alumina, zirconia and silicon nitride countersurfaces at 600 °C. The influences of load and countersurface materials on the tribological performance of this composite have been studied. The friction and wear test results indicate a low coefficient of friction and specific wear rate for alumina and zirconia countersurfaces at F = 1 N load (maximum Hertzian pressure â¼0.5 GPa). Examination of the worn surfaces using scanning electron microscope/energy dispersive spectroscopy confirmed the presence of copper rich layer at the edge of wear scar on the alumina and zirconia countersurfaces. However, Si3N4 countersurface sliding against CuO-TZP shows a relatively higher coefficient of friction and higher wear at 1 N load condition. These results suggest that the countersurface material significantly affect the behavior of the third body and self-lubricating ability of the composite.
