The wear resistance of titanium alloy is comparatively low, which becomes the technical bottleneck to use titanium alloy as high strength and corrosion resistance tubing materials in petroleum industrials. In this work, wear properties of TC4 alloy were studied. The relationship between temperature and weight loss rate of wear or wear coefficient or topography of wear mark, wear mechanism of TC4 alloy was discussed. The results show that the wear degree of TC4 alloy deceases with the rise of temperature, TC4 alloy wear has two stages that is wear stage and stable wear stage, The wear mark of TC4 alloy presents furrow morphology, the wear mechanism of TC4 alloy are delamination abrasion and adhesive abrasion and fatigue abrasion at lower temperature and are delamination abrasion and adhesive abrasion and oxidation abrasion at higher temperature
