Abstract

By using pin-on-disk wear test method, the wear behavior of W9Gr4V high speed steel with smooth and non-smooth concave samples which treated by laser texturing technology was investigated between room temperature and 500 . It was found that the anti-wear ability of the non-smooth concave samples was increased more than that of the smooth ones and the anti-wear ability of the non-smooth samples was evident than the smooth ones at temperature increasing. In this paper, the anti-wear mechanism of non-smooth concave samples and wear characteristics with smooth and non-smooth samples in high-temperature were analyzed.
