Effect of Zinc Coating Thickness on Corrosion Performance of Mild Steel in Atmospheric and Seawater Environment

Abstract:

The application of zinc coating as a protective film to the mild steel against corrosion attack in atmospheric and seawater environment was studied. The objective of this study is to evaluate the corrosion performance of mild steel coated by different thickness of zinc under salt spray and also immersion test. The corrosion measurement test was performed by weight loss and potentiodynamic polarization. From the experimental study, it was found that the corrosion rate of mild steel is inversely proportional to the zinc coating thickness. The result also showed that the corrosion rate of mild steel in the salt spray test is higher than the immersion test.
