Surface texturing technology is a microfabrication technique that enhances material surface properties by creating micro or nanostructures with specific geometries, dimensions, and arrangements on material surfaces. Owing to its remarkable advantages in improving the tribological performance of materials in mechanical friction pairs, surface texturing technology has been widespread applied in friction interfaces. This paper primarily reviews the reduction of friction achieved through the control of surface texture parameters. Specifically, it elaborates on how different manufacturing processes control these parameters, and how the resulting surface texture parameters influence friction reduction. Finally, it clarifies the underlying friction-reduction mechanisms. While the focus remains on the friction aspect of tribology, the explanation of mechanisms inherently involves lubrication, as friction-reduction mechanisms are intricately linked with lubrication.
