Zinc iron group metal alloys were deposited under coulostatic (10C.cm -2 ) at 40 ℃ chloride baths. The deposited alloys were quantitatively analyzed by Atomic Absorption Spectrometry. The current efficiency, percent content and partial polarization curves were obtained by the results. The morphology of the deposits was observed by means of Scanning Electron Microscopy(SEM). We observe that the electrodeposition of zinc iron group metal alloys is one of the best known examples of anomalous codeposition. We found the catalytic effect of Cl - on the electrodeposition behavior of iron group metal. Overpotential of iron group metal droped abruptly at high Cl - concentration, while transition current density of Zn increased gradually.
