Surface texturing technology, as a surface treatment technology, has been used to improve the tribological performance. In the paper, both SLM and surface texturing technology are used to prepare textured samples with different parameters. Under the conditions of dry and phosphate buffer solution (PBS) lubricated conditions, the tribological performance and the mechanism of the textured 316L SS were investigated. The texture parameters studied are characteristic size, area ratio and shape including single triangular, circular and composite textures composed of two shapes. Results show that under dry friction condition, compared with the untextured surfaces, the friction coefficients and wear losses of the three textured samples almost increased, and only the wear loss of the circular textured sample decreases. Under the condition of PBS solution, compared with the untextured surface, most of the friction coefficients and wear loss of the textured samples decreased significantly, but the wear loss of textured surfaces in group B shows an obvious increase. And reducing the characteristic size of the texture significantly increases the wear loss of the 316L SS sample. At the same time, the triangular textured samples have better wear resistance than the circular textured samples. Therefore, the application of surface texturing technology to 316L SS samples prepared by SLM, especially in the simulated body fluid conditions, can achieve the purpose of stable friction and reduce wear loss. Meanwhile, reasonable texture parameters have a greater impact on improving the tribological performance of 316L SS.
