General information on co-deposition
Electrodeposition of zinc alloys

Due to the complexity of the electrolytes used, the codeposition of metal alloys is less straightforward than the electrodeposition of a single metal. For two metal cations, ${\text{M}}_{\text{1}}^{\text{n+}}$ and ${\text{M}}_{\text{2}}^{\text{n+}}$, to reduce simultaneously at the cathode, they must be brought to the same discharge potential E_d during electrolysis [1]. To achieve this, it is necessary to impose a potential difference across the electrolytic reactor so that the cathode potential has a more negative value than that of the discharge potential of...
