description Surface texturing has gained significant attention in various engineering fields due to its tribological effects on materials. The process involves altering the surface topography of materials, which can potentially improve their lubrication, friction, and wear resistance properties. Such an improvement can greatly benefit the efficiency, performance, and service life of machines by reducing frictional losses and wear resistance effects. However, the optimization of surface textures varies and is dependent on the specific requirements of its applications. The two methods of surface texturing are laser surface texturing (LST) and mechanical texturing by means of deep cold rolling (DCR). LST is considered to be the most effective method of improving tribology due to its precision, time, cleanliness, and cost savings. However, LST lacks in producing other mechanical enhancements such as improved strength and wear resistance, which can be achieved through DCR.
