FRICTION AND WEAR PROCESSES IN TRIBOTECHNICAL SYSTEM

: Friction and wear processes take place in the surface layer, which plays a special role in the tribotechnical system. Plastic deformation of the surface layer during friction causes specific structural changes (fragmentation of the structure) and the development of stress concentrators of different scales (bifurcation centers). With structural self-organization, bifurcation centers are transformed either into dissipative sources and generators of various carriers of plastic deformation or into centers of material destruction.
