Summary

The aim of the present paper is to show the high tribological potential of laser surface modified Al2O3. Therefore, alumina was modified using CO2-laser irradiation by adding HfO2, TiN or W and ZrO2. Friction and wear of the modified ceramics were studied under oscillating sliding contact against alumina balls in a laboratory tribometer.
