Popis:	A physicochemical model is proposed for the conjugation of partial processes of hydrogen evolution and nickel ionization through a common intermediate stage of the surface dissociation of water. The model describes anodic and anomalous dissolution of nickel from the individual and intermetallic NiZn and NiZn3 phases. The acceleration of these processes on intermetallides is shown to result from a heightened concentration of defects and adsorbed hydrogen in the surface layers of the electrode.
