Abstract
In this study, ZnMn alloy coatings were potentiostatically deposited on steel substrate from a chloride acidic bath. The effects of glycine, sodium acetate and applied potential on deposit kinetics, morphological and structural properties of ZnMn coatings were studied. The voltammperometric analysis indicated that the simultaneous codeposition of two elements Mn and Zn was possible under our experimental conditions. However, the deposition kinetics depends strongly of the additive type. The morphological and structural properties of ZnMn deposited with sodium glycine and acetate are completely different, indicating that electrodeposition process changes according to the additive type. The best microstructural and crystalline properties were obtained at low deposition potential in the presence of acetate.
