Abstract: It is shown by cyclic voltammmetry and potentiostatic determination that, charge transfer in the electrodeposition of Al on Mo from AlCl3-NaCl-KCl melt is reversible; the diffusion coefficient of Al2Cl7- ions is quite small, and so are the nucleation rates and the saturated nucleus number densities, suggesting that by ordinary DC electroplating it is impossible to get high quality electroplates of pure Al with fine grains from this melt.
