【 摘 要 】

The mechanism of laser surface micro-texture on friction characteristics of 45 steel surface was studied. The micro-texture was characterized and measured by 3D geometric parameters. The orthogonal experiment method was used to optimize the laser processing parameters. The friction and wear experiments were performed on the smooth samples and textured samples. The results show that micro-texture with reasonable size is conducive to reduce friction and drag. This has certain reference and theoretical basis for the study of the relationship between surface geometry and service performance.
