Research Progress on Tribological Properties of Laser-Textured Solid/Liquid Self-Lubricating Surfaces

It enables precise fabrication of micro/nano-scale structures with tailored geometry, dimensions, and spatial distribution on material surfaces, substantially enhancing lubrication performance and wear resistance of friction pairs.

This review systematically examines the processing mechanisms of LST, the effects of key texturing parameters—such as area density, geometric morphology, size, and depth—on tribological behavior, and the synergistic roles of textured coatings (e.g., metal-based, sulfide-based, and organic/inorganic composites) under various lubrication regimes. Studies show that rational texture design can enhance hydrodynamic lift, promote lubricant film formation, and trap wear debris, leading to significant reductions in friction coefficient and wear rate.
