The present study describes effects of texture geometry, including area fraction and size of dimples, fabricated by fine particle peening on cast iron ring was analyzed using a ring on disc type testing apparatus in boundary lubricated condition. Alumite film formed on an aluminum cast alloy disc was applied as the mating specimen. Glass beads with various diameters was used as the impact media and was accelerated with pressurized air to collide the target iron surface. The size and the area fraction was controlled with the media size and peening time. As results, It was found that the surface texture consisted from small dimple diameter with the area fraction of 15 % was the most effective for reducing the friction resistance.
