Abstract
This article discusses changes in time of certain electrochemical properties (corrosion potential, Ψ′-potential, and corrosion inhibition coefficient) under residual protective action within corrosion of Zn and Fe. These properties reflect stage-by-stage desorption of preliminary adsorbed inhibitor. The pattern of their changes in time is explained in terms of changes in adsorption interaction metal-inhibitor taking into account the essence of metal and inhibitor. Rather high coefficients of acid-corrosion inhibition of Fe and Zn are attributed to the simultaneous action of some specific factors, which increase adsorption of inhibitor on metals.
