Electrodeposition of Zn-Mn alloys were carried out in an acidic chloride bath. The influence of electrolytic bath composition and deposition parameters on the alloys’ composition, cathodic current efficiency and corrosion properties were examined. It was found that the composition of plating baths and deposition potential have significant effect on manganese content and Zn-Mn deposit morphology, as well as on the corrosion properties of the alloy. Linear and Tafel polarization studies showed that the incorporation of Mn in the Zn enhances the corrosion resistance when compared to bare Zn. Anodic passivation studies indicated two orders of magnitude lower passivation current for the Zn-Mn alloy (17% Mn) when compared to that of Zn. |
