Abstract
Plasma surface alloying (PSA) technique was employed with nickel as incident ions to prepare the TiNi/Ti2Ni alloyed layer on surface of Ti6Al4V. High-temperature friction and wear performance of TiNi/Ti2Ni alloyed layer and the Ti6Al4V substrate were evaluated at 500[Formula: see text]C. The results indicated that the TiNi/Ti2Ni alloyed layer exhibited superior high-temperature wear performance. The variations of friction coefficient were the same rule but wear rate was lower compared to Ti6Al4V substrate. The wear mechanism of TiNi/Ti2Ni alloyed layer was mainly slight abrasion and the Ti6Al4V substrate showed abrasion and oxidation wear. The friction coefficient of the TiNi/Ti2Ni alloyed layer decreased from 0.90 to 0.50 with the increase of temperature from room temperature to 500[Formula: see text]C.
