Temperature Dependences of the Reaction Rate in Tribochemical Kinetics

Based on the material considered, assumptions are made about the dependence of the reaction rate on temperature, which should be properly taken into account in mathematical models of the tribochemical kinetics of external friction. From the perspective of tribochemical kinetics, the study of the dependence of the reaction rate on temperature is reduced to the need to explain the increase in the friction force after it decreases and reaches a minimum with an increase in the sliding velocity. In the context of the models studied, this behavior reflects the trend for a linear increase in temperature in the region of the topochemical reaction of the adhesive setting with an increase in the sliding velocity and a linear dependence of the decrease in energy and activation of the formation and growth of adhesive setting nuclei on the contact patches of friction surfaces.
