英文摘要	Fretting wear behavior of TC4 alloy was studied under various contact loads at 300 and 500. Surface wear track morphology, wear volume and wear track profile were characterized by scanning electron microscope and laser confocal microscope to explore the fretting wear mechanism of TC4 alloy under different contact loads in the two temperatures. The results showed that the wear volume and the contact load present a positive correlation, while the friction coefficient and the wear rate present a negative correlation. In the process of lubrication fretting wear at two temperatures, the form of wear is oxidative wear and abrasive wear under the small load and oxidative wear and adhesive wear under the large load. Compared with 300, the surface exhibits larger plastic deformation, less friction coefficient, more intensifying oxidative wear and more extending fatigue cracks at 500. The fretting wear mechanism of TC4 alloy in high temperature environment involves adhesive wear, abrasive wear, oxidative wear and fatigue wear, in which the dominant function is oxidative wear. © 2022, Editorial Board of CIESC Journal.
