In order to elucidate the effects of the hardened depth and relative radius of curvature on the surface durability of carbonitrided steel rollers, chromium steel rollers with diameters of 30, 60 and 120 mm were fatigue-tested with pairs of the same diameter rollers under a sliding-rolling contact condition. The experimental results were discussed by the amplitude of the ratio of shear stress to the Vickers hardness. The surface failure mode in this experiment was spalling due to the subsurface cracking. The depth of the spalling crack agreed with the depth of the maximum amplitude of the ratio of shear stress to the Vickers hardness. The surface durability of the carbonitrided roller tended to increase as the hardened depth increased and the relative radius of curvature decreased.
