Samples of a Ti6Al7Nb were treated by gas nitriding for 3,5,7 and 12 h at 1120 degrees C. Gas nitriding provided formation of TiN layer whose hardness and thickness changed with respect to nitriding time. 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. Longer nitriding times yielded higher wear loss than shorter nitiriding times.
