Nitriding Behavior of Ti6A14V Alloy in Gas Atmosphere

Abstract

Samples of Ti6A14V were treated by gas nitriding in α-Ti and s-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 α-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 s-Ti field.
