Zn-Ni electrodeposition for enhanced corrosion

deposition occurs with the amount of the noble metal in the deposit falling below the concentration of the metal in the bath. This transition results from the formation of a critical concentration of zinc hydroxide at the cathode surface [21] which apparently hinders the discharge of Ni ions due to adsorption of zinc hydroxide formed as a result of
