entropy approach, tribocoupling of parts, self-organization, friction zone, property.


The role of entropy in the processes of friction and wear of tribocoupling materials of moving parts is clarified. The implementation of the effect of self-organization of materials depending on the production of entropy is theoretically substantiated. The conditions of self-organization with negative entropy production were obtained. The relationship between the rate of volumetric wear of tribocoupled parts and the production of excess entropy and its flow is determined. Expressions for the intensity of wear of tribocoupling parts were obtained, taking into account thermal processes in the friction zone. The trends of changes in the characteristics and properties of tribocouplers of components, systems and machine aggregates with a change in entropy have been clarified.
