It is shown how the characteristic deformation observed in wearing surfaces can be explained in terms of the wave model of asperity deformation. Possible explanations of the damage sustained by the surface with repeated wave passes, which eventually results in wear particles being formed, are given by considering the strain cycle undergone by material as it flows through the wave.
