Electrochemical Deposition and Characterization of Zinc-Cobalt

Various protective methods may be used to improve the corrosion resistance of steel. Electrochemical preparation of Zn-Co alloy has been investigated potentiostatically by using mild steel plate electrode. Electrodepositon of Zn-Co alloys have been applied to the production of highly corrosion resistance steel sheets for automotive body panels. Zn-Co alloy mostly used for industrial or commercial purpose. Organic additive used in Zn-Co coating to make the electroplated surface more durable, uniform and compact for better performances in terms of corrosion protection. Various concentrate solutions of HCl, H2SO4 and NaCl may be used for determining the corrosion rate of Zn-Co alloys. SEM, EDAX and XRD revealed the morphology, percentage composition and structure of Zn-Co coating respectively.
