Study on the Wear Properties and Wear Mechanism about TC4 and G3 Alloy Tubing Steel in Dry Condition

Article Preview

Abstract:

The wear property of TC4 alloy is focus of discussion for its being used in high strengthen and corrosion resistant of tubing material. In the present paper, the wear properties of TC4 alloy and G3 alloy tubing steel are investigated comparatively, the differences and similarities of the weight loss rate of wear, wear coefficient and topography of wear mark by the wear test and the topography analysis are analyzed, and then the wear mechanism is discussed. The result shows that the topography of wear mark of TC4 alloy is furrow morphology, but that of G3 alloy tubing steel is pit morphology. The wear resistant of G3 alloy tubing steel is obviously more excellent than that of TC4 alloy. The wear mechanism of TC4 alloy is exfoliation wear, adhesive wear and fatigue wear, and that of G3 alloy tubing steel is exfoliation wear and abrasive wear.
