摘要：

This paper introduces a new method of investigation in the field of fretting. This method employs X-ray diffraction for the characterization of surface layer damage through residual stresses and work-hardening by tribological action. The effect of hardness and material residual stresses upon the state of the surface have been studied. The results showed that fretting, being a surface phenomenon, created work-hardening of soft material or work-softening of hard material in the near-surface layers. When the initial residual stresses were high, fretting could not modify them because they had already reached the saturation limit. A Pole figure shows that fretting modified the texture of the specimen surface.
