dc.descriptionElectrodeposition of Zn on mild steel (MS) within an acid bath consisting of admixedZnCl2,H3BO3and KCl solution at specific concentrations of ginger (zingiber officinale), celery(Apium graveolens) and pomegranate (Punica granatum) extracts, and plating time was studied.The surface of electrodeposited MS was analyzed with scanning electron microscope (SEM). Energydispersive spectroscopy (EDS) was employed for elemental analysis. Results shows the presence andincrease in extract concentration is associated with the amount of Zn electrodeposited on MS. Gin-ger extracts induced the highest weight gain with values between 0.0867 g and 0.1219 g. Morphol-ogy studies showed good electrodeposition of Zn on MS, with closely packed Zn particles on thesurface with respect to additive concentrations and plating time. EDS results showed pomegranateinduced the highest %wt. content of Zn on MS. Corrosion resistance of the unplated and Zn elec-trodeposited MS with and without extract additives were evaluated with potentiodynamic polariza-tion method. Results showed the presence of ginger, pomegranate and celery extracts improved thecorrosion protection of Zn electrodeposited MS with optimal corrosion rates of 2.48 mm/y,2.78 mm/y and 1.95 mm/y compared to 7.96 mm/y for unplated MS and 6.58 mm/y for Zn elec-trodeposited MS without additives.
