Hydrogen entering at cathodic polarization produces the straining of Al. In the course of increased polarization, the elastic strain causing the up-hill diffusion of hydrogen present in metal and then the plastic deformation creating of hydrogen traps have been introduced. As a result, the unusual appearance of hydrogen permeation transients and the retardation of hydrogen transport and its accumulation within the plastically deformed metal occur at the low and at the high polarization, respectively. The supersaturation of surface layers with hydrogen or the formation of the patchy hydride like layer have been discussed to be the source of the observed metal straining.
