Kinetics of Mechanoactivation of Tribochemical Processes

摘要

Active collision theory and activated complex theory are used to derive the general kinetic equations of the mechanoactivation of tribochemical processes in systems with boundary and mixed sliding friction. The nature of the weak temperature dependence of the velocities of tribochemical reactions compared to the corresponding thermoactivated processes is discussed. Various specific cases of mechanoactivation kinetics are considered and some of them are illustrated using examples of reactions with the selective transfer and wear of rubbing solids.
