Abstract: Electrodeposition of zinc-manganese alloy was attempted from sulphate bath containing condensation product (CP) of furfuraldehyde (FRL) and L-lysine monohydrochloride (LL). The effect of bath constituents, pH, current density and temperature on nature of deposit was studied through Hull cell experiments. The throwing power was measured using Haring and Blum cell. The bath constituents and operating parameters were optimized. Deposit properties and corrosion resistance were discussed. Current efficiency and polarization studies were carried out. SEM photomicrographs of the deposit obtained from optimum bath revealed that the condensation product modifies the morphology of zinc-manganese alloy deposit. IR spectrum of the scrapped deposit showed inclusion of addition agent.
