Corrosion Inhibition of Zinc in KOH Solutions

Article Preview

Abstract:

The influence of electrolyte additions on the corrosion of zinc in aqueous solutions of KOH has been determined using electrochemical and nonelectrochemical techniques. These included anodic and cathodic polarization resistance and potentiodynamic method. The inhibitors studied included ZnO and tetra-alkylammonium bromides in different concentrations. From the data provided corrosion currents were calculated. The effectiveness of the inhibitors was compared and it was found that combinations of zinc oxide with tetra-alkylammonium salts were the most effective. Surface analysis obtained with scanning electron microscopy (SEM) revealed morphology characteristics developed at the zinc surface.
