“…1.1, а). Polarized "reflection" of the metal ion in the polymer matrix can be considered as a quasiparticle with a negative charge that is equal in absolute value to the metal ion charge and effective mass equaling to the mass of such ion [9,10]. If the time period for metal ion transfer to the dielectric is less than the relaxation time, image 1, а is transformed as shown in Fig.…”

“…An equally important contribution to the development of quantum tribology, as an important component of modern quantum physics of macrosystems, is the description of friction interaction as a special case of exchange forces [3]. Among the works devoted to the development of this field, the friction model proposed by the Soviet physicists E. Adirovich and D. Blokhintsev, numerous studies on the phonon friction mechanism and, of course, the tribon hypothesis of the Ukrainian scientist L. Bershadsky can be distinguished [4]. The development of the ideas of the latter in the works [5][6][7] showed the existence of a linear relationship between the number of tribons and the main tribotechnical characteristics, for example, the friction coefficient.…”

In the theory of friction, there are many approaches to the description of the frictional interaction of condensed bodies. However, recently, those models in which the frictional interaction is described from positions close to quantum mechanical exchange forces (Adirovich-Blokhintsev, phonon friction, the hypothesis of the Bershadsky tribon model) are acquiring an increasing interest. The tribon model of friction interaction was developed and described in detail by the authors in a number of papers and monographs. The main research result was the obtaining of a linear dependence between tribotechnical parameters and the number of tribons generated in the tribocoupling. It was found that weak absorption of tribons leads to the formation of strong frictional bonds and, consequently, high values of the friction coefficient and wear. The tribon model simplifies the thermodynamics of friction, including its physical apparatus, connecting the entropy increase and the generation of tribons.

“…This opens wide possibilities for theoretical comprehension of the obtained analytical expression through the quantum and mechanical characteristics of the tribosystem elements appeared in it as well as the conditions for its testing (work). In addition, it is possible to carry out an experimental test of expression (9) to estimate the evolution of the tribosystem and its constituent elements. In turn, while assessing the evolution of the tribosystem it is possible to determine evolving in terms of development and in terms of degradation of elements.…”

It is noted that while analyzing the tribosystems evolution it is potentially productive to use the methods of modern thermodynamics, nonlinear mechanics and quantum theory. Using the understandings of nonlinear dynamics and quantum-exchange interaction of solids surfaces an analytical expression is obtained for calculating the magnitude change of the tribosystems entropy. The expression for estimating the change in the tribosystems entropy is explicitly contained the tribotechnical parameter that is reciprocal to the wear. The case of relation between the tribosystems entropy change (decrease) and its wear resistance is analytically confirmed. The analytical expression for estimating the entropy change contains only those mechanical and physical parameters that can be measured by using modern physical methods. This allows to do not only an experimental verification of the obtained analytical dependence but also numerically evaluate the influence of the parameters of the tribosystems basic elements and its operating modes on the entropy values. In addition, it is possible to evaluate the tribosystems evolution itself and its constituent elements in the direction of their development or degradation. The obtained in this case data will allow proposing corrective structural and technological measures aimed to extend operational life of degrading elements and the tribosystem as a whole.
