“…This process is dissipative structures. Such real broken dependences are described, for example, for cutting tool [25,26]. In [25,26] and in Figure 1c,d friction conditions allow passage of self-organization, i.e., the thermodynamic stability of the tribosystem may be lost under these conditions.…”

“…Therefore, in spite of compliance with the necessary conditions of stability loss from the beginning of friction, self-organization (the breaking in the curves) occurs after a sliding distance has been traveled. That is not self-organization since the beginning of friction (Figure 1c,d) shows that on the dependence of the wear (wear rate) on the friction parameter in [25,26]-a cutting rate bifurcation is possible. One branch after the bifurcation point (thermodynamic)-a characteristic dependence In the case where there is no self-organization, the wear ( Figure 1a) and reduction of the intensity of wear (Figure 1b) are shown by smooth and gradual curves.…”

Application of the phenomenon of self-organization for the development of wear resistant materials has been reviewed. For this purpose the term of self-organization and dissipative structures as applied to tribology have been discussed. The applications of this phenomenon have been shown in order to develop new wear resistant-and antifriction materials. Specific examples have been shown for the application of the self-organization phenomenon and the generation of dissipative structures for the formation of tribotechnical materials with enhanced wear resistance for current collecting materials and antifriction materials of bearings.

“…As outlined above, these amorphous films, which are SS-I, have high plasticity and improved lubricating properties [130]. Under more severe cutting conditions (machining of annealed 1045 steel at cutting speeds of 250-450 m min −1 ) cemented carbide tooling has been used with TiAlN nanocrystalline coatings [186]. A more complex phenomenon takes place on the friction surface.…”

Adaptive wear-resistant coatings produced by physical vapor deposition (PVD) are a relatively new generation of coatings which are attracting attention in the development of nanostructured materials for extreme tribological applications. An excellent example of such extreme operating conditions is high performance machining of hard-to-cut materials. The adaptive characteristics of such coatings develop fully during interaction with the severe environment. Modern adaptive coatings could be regarded as hierarchical surface-engineered nanostructural materials. They exhibit dynamic hierarchy on two major structural scales: (a) nanoscale surface layers of protective tribofilms generated during friction and (b) an underlying nano/microscaled layer. The tribofilms are responsible for some critical nanoscale effects that strongly impact the wear resistance of adaptive coatings. A new direction in nanomaterial research is discussed: compositional and microstructural optimization of the dynamically regenerating nanoscaled tribofilms on the surface of the adaptive coatings during friction. In this review we demonstrate the correlation between the microstructure, physical, chemical and micromechanical properties of hard coatings in their dynamic interaction (adaptation) with environment and the involvement of complex natural processes associated with self-organization during friction. Major physical, chemical and mechanical characteristics of the adaptive coating, which play a significant role in its operating properties, such as enhanced mass transfer, and the ability of the layer to provide dissipation and accumulation of frictional energy during operation are presented as well. Strategies for adaptive nanostructural coating Topical Review design that enhance beneficial natural processes are outlined. The coatings exhibit emergent behavior during operation when their improved features work as a whole. In this way, as higher-ordered systems, they achieve multifunctionality and high wear resistance under extreme tribological conditions.
