Abstract

Samples of a Ti6Al4V alloy were treated by thermochemical gas nitriding at 1120 degrees C for 7 h. Gas nitriding provided formation of titanium nitride layer with a hardness over 1800 HV. The titanium nitride layer exhibited excellent wear resistance along with a lower coefficient of friction against alumina ball under dry sliding conditions when compared to the as-received state.
