Characterization of zinc-nickel alloys obtained from an industrial chloride bath

Zinc-nickel electrocoatings obtained from an industrial bath containing two additives were characterized by analysing their morphology, structure, mic rohardness, residual stress and corrosion resistance. Changes in deposit ch aracteristics following the addition of saccharin were also studied. All co ating, with or without saccharin, presented a good appearance, good mechani cal properties and a high corrosion resistance. Moreover, by varying certai n plating conditions it was observed that the deposits maintained their pro perties over a wide interval of experimental conditions, which suggests the ir suitability for use in batch bath.
