Abstract
Abstract Electrodeposition and stripping of Zn, Mn and Ni metals and their alloys were investigated in an aqueous sulfate solution. The effect of coating processes and its impact on the substrate were evaluated by investigating the prepared alloys with X-ray diffraction analysis, scanning electron microscopy and atomic absorption spectroscopy. The electrodeposition mechanism of the Zn-Ni-Mn alloy was found to be an anomalous type. The high corrosion resistance of the Zn-Ni-Mn alloy, as well as its preferable surface appearance, has been ascertained compared with the electrodeposited Zn-Ni alloy under homogeneous conditions. It was found that Mn can be codeposited with Ni or with Ni and Zn understudied conditions where it does not deposit in its pure form. During electrodeposition of manganese alone or manganese alloys, a dark brown deposit was formed on the counter platinum electrode surface as a result of oxidation to manganese dioxide.
