Friction and Wear of Commercially Pure Titanium with Different Microstructure from the View Point of Thermodynamic Analysis

“…In the process of friction, energy conversion takes place, therefore it is natural to consider the mechanism of friction and wear from the point of view of thermodynamics. Since friction is a non-equilibrium process, and the main phenomena occurring during friction are concentrated in the thin near-surface layer, of scientific and practical interest are the aspects of friction based on the thermodynamics of non-equilibrium processes and self-organization [2,3].…”

“…The non-equilibrium processes in a tribosystem may lead to a decrease in entropy production and consequently, a decrease in wear rate, and can run stably under the formation of dissipative structures during self-organization (adaptation) [2][3][4][5]. The process of self-organization can start only after a system passes through instability [2][3][4][5]. A system can lose its stability under negative excess entropy production (in accordance with a Lyapunov function [3]).…”

“…The process of self-organization can start only after a system passes through instability [2][3][4][5]. A system can lose its stability under negative excess entropy production (in accordance with a Lyapunov function [3]). For self-organization of a tribosystem, more than one independent process should occur in it [2][3][4][5].…”

“…A system can lose its stability under negative excess entropy production (in accordance with a Lyapunov function [3]). For self-organization of a tribosystem, more than one independent process should occur in it [2][3][4][5]. In actual systems, in addition to friction, other independent sources of energy dissipation are always present as well, such as the physico-chemical interactions of rubbing bodies with each other, environment and lubricant, which lead to a change in the composition of surface structures.…”
