Abstract
Electrodeposition of zinc–iron-group metal alloys is carried out in a methanol bath. The effects of different parameters, such as bath composition and current density on current efficiency and alloy composition are investigated. Partial polarization curves of zinc and nickel are measured for both alloy and single metal deposition to evaluate the codeposition behaviour of zinc–iron-group metal alloys. Attempts are also made to confirm the proposed hydroxide suppression mechanism explaining the anomalous type of codeposition of zinc–iron-group metal alloys by investigating the role of water in the electroreduction process of zinc and iron-group metal ions.
