Electrostatic fields in the contact zone between a finite-sized impurity and a corroding conductive surface are determined. The electrostatic structure of the liquid film involved in the development of electrochemical corrosion of a metal surface is discussed. To solve this problem, it is necessary to consider the image forces between the film ions and the metal surface, as well as the presence of metal electrons penetrating the film due to the metallic proximity effect. The resulting double-charged layer facilitates the transition of corrosive metal ions into the liquid film, stimulating corrosion development. A comparison of the empirically determined series of electrode potentials for a number of metals (in ascending order) with data on the contact energy of electron release for these same metals is proposed. A significant correlation between these series is evident.
