Abstract

Ni-Mo alloy deposits with (111) preferred orientation was obtained in a solution of 0.22 mol/L NiSO₄·6H₂O, 0.06 mol/L Na₂MoO₄·2H₂O and 0.3 mol/L Na₃C₆H₅O₇·2H₂O in temperature from 25℃ to 50℃, and current densities ranged from 10 mA·cm^-2 to 30 mA·cm^-2. The electrodeposition of Ni-Mo alloy was studied by cylic voltammetry and potential step experiment. It was shown that Ni-Mo alloy is formed by mechanism involving progressive nucleation followed by three dimensional growth of the metal centres. The complex plane impedance plots indicate codeposition of Ni-Mo alloy involves the intermediate adion.The growth of (111) plane of crystallite is inhibited with adsorption of (NiOH)_ads and MoO₂, So-Ni-Mo alloy deposit exhibits (111) preferred orientation.
