The main objective of the research work was mainly focused on Electroplating of Zinc on mild steel obtained by exhausted batteries leach solution using hull cell experiment for corrosion protection, which gives excellent corrosion resistance when used as coating material on mild steel. The mild steel was deposited into solution of zinc bath for varying voltage between 0.5 V and 2.0 V.It was found that the sample plated at 1.5V for 10 minutes gives the best plating surface finish. The Elemental composition and surface morphology of the coatings were analyzed by energy dispersive X-ray spectrometry (EDS), scanning electron microscopy (SEM).Surface area and line roughness of Zn coated samples were studied by Atomic force microscopy (AFM), micro hardness (HVN) and Open circuit potential (OCP), Taffel, and electrochemical impedance spectroscopy (EIS) were characterized by using Electro chemical work station for corrosion studies. The corrosion resistance was analyzed using 3.65% NaCl solution.
