The results of a complex comparative investigation of micro- and mesostructure, wear debris morphology, tribological behavior and mechanics of plastic deformation under friction of steel 45 in the initial and ion-implanted states are presented. A new approach to the description of plastic deformation and destruction under friction was introduced on the basis of the concept of structural levels of plastic deformation and physical mesomechanics. The formation of the modified structural-phase state in the surface layer of the Mo ion-implanted specimens is shown to prevent the fragmented structure formation at the mesolevel and retard the vortex movement of mesofragments in the subsurface layer, thereby decreasing the intensity of the debris particle formation and improving wear resistance.
