Topokinetic model of active dissolution of a solid electrode with point lattice defects. analysis and comparison of the results obtained in solving equations with the experimental data

Abstract

A model that takes into account the consistence between the atomic relief with the metal dissolution (corrosion) rate and also considers the direct effect of point lattice defects (vacancies or atoms of impurities with the corrosion resistance far deviating from that of the base metal) on this consistence is compared with experimental data. Despite the substantial simplifications taken in this model, the latter makes it possible to explain the main manifestations of effect of defects on the metal dissolution rate.
