Abstract
Surface texturing is considered a potential solution for improving the tribological properties of in-contact surfaces. It offers several benefits, including reduction of contact area, enhanced load-bearing capacity, lubricant and debris storage, and governing change between lubrication regimes. In recent advancement in the field, several surface texturing techniques have emerged. Among these methods, laser surface texturing (LST) has garnered considerable interest due to its high flexibility, superior texturing accuracy, and good controllability. This paper reviews the strategies and influential parameters to reduced friction by surface texturing and presents overview of the laser surface texturing mechanism and environment of laser ablation, texture shape, depth, density, lubricants, and factors effecting friction performance. Further the present challenges, applications and prospects are discussed.
