This paper describes a study on the surface durability of plasma-carburized rollers. Test rollers of MAC14 and SCM415 steels were plasma-carburized under different carburizing conditions. The contact fatigue tests were carried out for these test rollers. The effects of case depths on the contact fatigue strength of rollers were determined. The effect of shot-peening on the contact fatigue strength was also examined by carrying out contact fatigue tests for shot-peened rollers. The results were compared with the results for super- or eutectoid-carburized rollers. The contact fatigue strengths of plasma-carburized rollers become larger with an increase of case depth and are larger than those of super- or eutectoid-carburized rollers. The surface failure modes of plasma-carburized rollers were spalling. The load bearing capacity of plasma-carburized rollers was found to become larger by shot-peening.
