New advances in triboelectrochemistry: from steady state to impedance of abraded stainless steel in acidic medium

Résumé

The present paper reports on the application of EIS in triboelectrochemistry. Electrochemical measurements were performed at the constant dc current attained during a permanent regime of friction achieved by a rotating Pin-on-Disc (P-o-D) tribometer. A model is then proposed which embodies a classical kinetic description of an active-passive transition into the accepted description of the tribo-electrochemical response of a passive material. From the derivation of the equation at steady-state, a set of parameters were determined allowing to describe correctly both the dc and ac behaviours of the interface and to estimate the different components of the tribo-electrochemical signals.
