Influence of hexamethylenetetramine on electrochemical process of Zn-electrodeposition
The influence of hexamethylenetetramine (HMTA) on the Zn electrodeposition process was analyzed using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques.The results of CV analysis showed that the adding of HMTA shift the reduction potential of Zn electrodeposition to more negative values,indicating that the adsorption of HMTA on the active sites of the metal substrate hindered the nucleation and growth process of the Zn electrodepesition which happened under a larger cathodic overpotential.At the same time,The corrosion resistance of the Zn deposition was increased with the presence of HMTA.
