Triboelectrochemistry of the 'wearless' effect. the friction influence on the electrochemical characteristics of the frictional contact in the primary stage of the 'wearless' effect

摘要

The investigations of the evolution of the stationary potential of the friction surface under the transition of the system "brass-glycerin-steel" in the regime of the "wearless" effect were carried out. The change of the stationary potential maybe connected with formation and persistent change of a structures and properties of the surface layers, with alternation of "activation-passivation" cycles during a corrosion processes under friction and with autocatalytic "avalanche" mechanism of theformation servovit film on the friction surface. The results show on necessity to take into account the electrochemical characteristics of the frictional contact for discussion of the self-organization mechanism at friction.
