Evaluation Of Corrosion Resistance Of Mild Steel And Aluminium Using Anodic Inhibitor Method And Passivity

Abstract

Mild steel and Aluminium considered from the metals that commonly used in engineering applications with a high proportion of up to 85%. On the other hand, due to the weakness of its resistance to corrosion environments different methods of corrosion protection are required to increase the resistance level particularly in the marine and acidic environments, where this give the significance of this study to be presented. This research involves studying the effect of some different corrosion resistance of mild steel and Aluminium by applying anodic inhibitor of mild steel (Sodium Dichromate and Potassium dichromate) in sea water environment and Aluminium by using passive film of Al2O3 in acidic environment (Hydrochloric acid HCL and Nitric acid HNO3). An experimental work has been done and evaluation of corrosion resistance have been measured from weight loss during different period of time.
