Wear characteristics of rolling contact surface operated at a higer contact stress, a low speed and high temperature were evaluated. Chromium alloy steel (SUJ2) roller and ring specimen were used for the experiment. A surdace modification process consisitinf from a micro shot peening and a roller burnishing was applied to the ring surface to improve the wear properties. Results showed that the oxidation film formation of the roller and ring surfacewas different dpending on the roller surface profile. It was also found that the micro shot peening process using the relativel larger impact meda is effective means to reduce the wear loss of the mated roller surface.
