摘要
The new approach to the kinetics of triboreactions, based on a mathematical model denoted as αi model implies energy emitted by the surface as impulses in the range of 1–5 eV. This communication looks for a better understanding of the mechanism of triboreactions by explaining the αi model, proposed previously in terms of the thermodynamics of irreversible processes. The reaction rate Jc found by non-equilibrium thermodynamics is also consistent with two superimposed pathways for tribochemical reactions. In the former, the reaction follows the thermal mechanism typical of no friction conditions, in the latter, direct transfer of energy from triboelectrons to molecules generate special excited or activated molecules A*, such as radicals or ions which react rapidly to form the products, enhancing the global reaction rate.
