It has been found that wear of the claddings is characterized by plastic deformation and local accumulation in the subsurface region at the early sliding stage. Then cracks were generated in the borders of different phases and grains. The cracks tended to extend, grow, and finally detach from the surface layer of the cladding, with the formation of wear debris.
