Investigation on Dimples Distribution Angle in Laser Texturing of Cylinder–Piston Ring System

The effectiveness of laser surface texturing in reducing wear rate was studied, with emphasis on dimple distribution angle. Experiments were performed by varying the texturing parameters to derive variational rulesof the wear scar depth on laser-textured cylinder walls under starved lubrication conditions, and the optimum laser texturing dimple distribution angle was obtained. It was found that the laser texturing could result in less wear rate compared to mechanical honing.
