抄録

  The electrodeposition behavior of Zn-Ni alloys produced from acidic sulfate solution were investigated via the partial polarization curves produced during alloy electrodeposition. The current density at which the co-deposition of Zn-Ni alloy produced anomalous results, we found that the Zn deposition is polarized and affected by the bath Zn concentration and flow rate. This indicates that at high current densities the Zn deposition is controlled by diffusion. Under the conditions to increase Zn deposition we found that Ni deposition was not suppressed, even in the region of anomalous co-deposition. At low pH bath condition Ni concentration in deposit was not increase under high current density, because of strong suppression of Ni deposition under low pH condition.<br>
