Abstract
The electrodeposition of zinc from acidic sulphate bath on steel substrate has been studied. The influence of sodium dodecylbenzenesulfonate (SDBS) as surfactant on the mechanism of the electrodeposition process has been investigated using potentiodynamic and cyclic voltammetry (CV) techniques. From the analysis of CV analysis, it is shown that in the surfactant free bath solution, hydrogen evolution occurs together with the zinc deposition. The presence of SDBS shifts the reduction potential of Zn2+ to more negative values, indicating that SDBS to some extent hinder the Zn electrodeposition.
