Abstract
The surface micro-texturing technology for controlling the topography of friction interface surfaces represents a crucial method for shape regulation. This study investigates the effects of texture shape on tribological performance by texturing square, rhombic, and elliptical micro-textures on the SUS304 surface. Principal component analysis is utilized to decompose the friction coefficient, elucidating the textured surfaces’ friction mechanisms. The results indicate that different texture shapes influence the friction coefficient of the friction pair, the stress distribution at the friction interface, and the wear characteristics. Under lower loads, the rhombic-textured material demonstrates the most effective friction reduction, with an average friction coefficient reduced by 45 % compared to untextured samples, and a minimum wear rate of 1.03 × 10-5 mm3/(N·m).
