摘要：

The phenomenon of acid corrosion of metals is analyzed with consideration of the cooperative nature of the proton subsystem of aqueous acid electrolytes and the electronic subsystem of a metal. The necessity of studying the cathodic evolution of hydrogen in terms of solvent reorganization is justified. The concepts of the anodic dissolution of iron metals are reviewed retrospectively. An important role of the solvation of dissolved metal ions in the anodic dissolution is shown. The limiting currents of the kinetic nature at high anodic overpotentials are discussed in terms of the dynamics of atomic steps and the motion of dissolution solitons.
