Abstract: Zinc was electrochemically deposited from non-cyanide alkaline bath solution containing condensation product formed between anthranillic acid (ANA) and furfural (FFL). The bath constituents and bath variables were optimized through standard Hull cell experiments. Current efficiency, throwing power, cathodic polarization and corrosion behaviour in 3.5% NaCl were studied under optimum concentration of additives and their effects were reported. Tafel polarization curves of the electrodeposited layers in 3.5% NaCl solution have been drawn. Weight loss and open circuit potentials were measured in order to study corrosion behaviour of zinc coated samples with and without additives. Structure of the deposits were characterized using scanning electron microscopic technique.
