Abstract

Samples of Ti6Al4V were treated by gas nitriding in alpha-Ti and beta-Ti field. Gas nitriding provided formation of TiN layer with a nitrogen diffusion zone beneath it. In the scope of the present study, after structural characterization of the nitrogen exposed surfaces, dry sliding wear tests were conducted. The sample nitrided in alpha-Ti field exhibited better wear resistance along with a lower coefficient of friction against alumina ball under dry sliding conditions when compared to the sample nitrided in beta-Ti field.
