The influences of the oxidized and nonmartensitic layer, produced during carburizing process, and surface roughness on pitting fatigue strength have been investigated. In order to elucidate the influence of the oxidized and nonmartensitic layer, carburized SCr420 steel rollers were fatigue- tested after chemical polishing that remove the oxidized and nonmartensitic layer and were compared with the ones without chemical polishing. In order to elucidate the influence of surface roughness, shot-peening was applied before carburizing to make the surface rougher. The results show that the pitting fatigue strength became decrease when the oxidized and nonmartensitic laver remained at the end of the test. In the case that the oxidized and nonmartensitic layer was not removed before the test and the initial surface roughness Ry is more than 4μm, the surface layer wore drastically during the test. Therefore, the oxidized and nonmartensitic layer wore out and the final surface roughness was smaller. The final surface roughness determines the pitting fatigue strength and so the pitting fatigue strength can be predicted using the relationship between initial and final surface roughness.
