Theoretical advances in the kinetics of tribochemical reactions

“…which resembles the equation for C reported by Kulczycki and Kajdas [20]. Finally, entropy production takes the following form…”

“…This equation for C is equivalent to that obtained by Kajdas and Kulczycki [20]. The expression of the reaction rate J c of Eq.…”

“…This model was described in detail in a previous paper [20], and can be called the a i model, which hypothesizes that the catalyst emits impulses of energy flux of high density for tribocatalyzed heterogeneous processes, and at the specific angle c the value of emitted energy is equal to the real activation energy E a . Detailed considerations of the developed model in relation to empirical results of tribological processes allows us to propose a new approach aiming at better understanding tribochemical catalytic processes.…”

“…In this model, there are two independent variables: applied load L and chemical structure of lubricant (CSL), i.e. the reagent in the case of the report by Kajdas and Kulczycki [20]. The latter variable was often given qualitatively, but it was necessary to express it as a quantitative variable, if the tribochemical process was to be described by mathematical dependence.…”
