“…As was noted [1][2][3] , the adsorbed hydrogen strongly affects the dissolution kinetics of iron, which contributes to anomalous anodic behavior of the metal upon its preliminary cathodic polarization, including the change in the slope of the anodic polarization curves, the current hysteresis at a potential scan in opposite directions, and so on. Ideas about the effect of hydrogen on the dissolution kinetics of iron are usually qualitative because of the absence of reliable data on the amount of adsorbed hydrogen.…”
