Abstract: In the present work, electrodeposition of Zn-Co alloy from sulphate bath has been carried out in presence of brightener, the condensation product of vanillin and serine. The investigation on electrodeposit has been carried out using cyclic voltammetry and galvanostatic techniques, while polarization and electrochemical impedance spectroscopic techniques are used for corrosion studies. It is found that the deposition current density has a great influence on the corrosion resistance nature of the coatings. The reflectance and scanning electron microscopic studies show the formation of bright coatings.
