The present study describes effects of surface dimples fabricated by fine particle peening to cast iron surface mated with aluminum alloy on friction and wear properties in boundary lubricated condition. The newly developed peening apparatus which enables to from isolated particle impacts is applied for the dimple fabrication. Aluminum specimens with different surface finish were prepared to evaluate influences of the surface roughness on the tribological properties of dimpled specimens. As results, it was found that the contribution of the dimples fabricated on the cast iron ring surface on the reduction of the friction resistance and the wear loss occurred in the results of coarse finished disc and that the dimples acted as not only oil reservoirs but also as entrapment of the wear debris.
