Performance Evaluation of Zinc Deposited Mild Steel in Chloride Medium.

The effect of deposited mild steel under plating variable influence was investigated in a chloride medium. The results showed homogeneous layer with improved surface adhesion after deposition. The distance between the anode and the cathode on voltage, plating time and coating thickness were observed. The mild steel was deposited into solution of zinc bath for varying voltage between 0.6 v and 1.0v. It was discovered that the sample plated at 1.0v for 15 minutes gives the best plating surface finish. Analytical study using potentiastat/galvanostat, focused ion beam scanning electron microscopy (FIB-SEM), XRD and AFM were used to determine the surface characterization, topography and corrosion evaluation of the substrate
