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).

干滑动条件下织构形状对金属摩擦副摩擦学行为的影响：有限元分析与表征

控制摩擦界面表面形貌的表面微织构技术是一种重要的形状调节方法。通过对SUS304表面的方形、菱形和椭圆形微织构进行织构，研究了织构形状对摩擦学性能的影响。利用主成分分析法对摩擦系数进行分解，阐明了织构表面的摩擦机理。结果表明，不同的织构形状会影响摩擦副的摩擦系数、摩擦界面处的应力分布和磨损特性。在较低的载荷下，菱形织构材料表现出最有效的摩擦减少效果，与未织构材料相比，平均摩擦系数降低了45%，最小磨损率为1.03 × 10-5 mm3/（N·m）。
