The present study describes the applicability of fine particle peening on surface modification of aluminum cast alloy in boundary lubricated condition against alloy steel. The specimens with modified surface were prepared with different treatment times. As results, the friction coefficient and the wear loss were larger at excess treatment of the peening and it was estimated that the crush of the silicon-rich segregated layer on the aluminum cast alloy during the sliding contact influenced on the wear loss of the alloy steel.
