Abstract: TD3 titanium alloy was nitrided by plasma surface nitriding technology, and microstructure, phase composition and hardness of the nitrided layer were tested. The friction and wear experiments of the TD3 alloy before and after nitriding were carried out at room temperature (25 ℃) and 600 ℃ respectively, and the effect of friction temperature on the friction coefficient, wear scar morphology and wear rate of which were analyzed. The results show that after plasma nitriding, a certain thickness of nitrided layer is formed on the surface of the TD3 alloy. While reducing the friction coefficient, the nitrided layer significantly reduces the wear rate of the TD3 alloy. When the temperature rises from 25 ℃ to 600 ℃, the wear scar morphology changes greatly, and the friction coefficient and wear rate also increase to a certain extent.

Key words: TD3 titanium alloy, plasma nitriding, friction coefficient, wear scar morphology, wear rate
