Description
In order to elucidate the influence of residual stress on pitting fatigue strength, fatigue tests were carried out with carburized SCr 420 steel rollers on various conditions of shot peening. The resuits for rollers with the oxidized and nonmartensitic layer show that the fatigue strength increases with shot peening, and it is remarkably in the case that the oxidized and nonmartensitic layer wore out during the test. On the other hand, the resuits for rollers, that the oxidized and nonmartensitic layer was removed in advance, show that the fatigue strength decreases with shot peening. However, in each case, it is necessary to deduct influence of surface roughness and hardness, so it is becomes clear that residual stress makes the pitting fatigue strength improve. In the case that the fatigue strength decreases with shot peening, the effect of residual stress is regarded less than that of surface roughness and hardness.
