The purpose of this study is to investigate the effects of the geometry and distributions of dimples on the frictional behavior of cast iron surfaces for applications in automotive engines under lubricated condition. Laser surface texturing method will be used to create micro dimples with various dimensions on cast iron surface. The pin on disc tester will be used to measure the friction and sliding wear properties. A comparison will be made between the performance of reference non-textured piston rings and optimum surface textured of piston rings. The density area of dimple is expected to reduce friction and wear up to certain value.
