Abstract: Zn-Mn-Mo alloys were electrodeposited from a citrate bath and the influence of various parameters such as current density, 2.0-6.0 Adm-2; temperature, 20-35ºC; pH, 2.0-2.15; duration of deposition 20-50 min and concentration of the constituent metals were studied. The electrolytic bath consists of zinc sulphate (20-35 gL-1), manganese sulphate (50-80 gL-1), ammonium molybdate (3-6 gL-1), citric acid (5 gL-1) and starch (1 gL-1). Semi bright, light gray adherent deposits were generally obtained containing 88.98-99.82% Zn, 0.06-8.70% Mn and 0.10-2.32% Mo. The variation of cathode polarization with current density or the pH under the conditions was studied. Morphological studies have also been done.
