Zinc-nickel electrocoatings obtained from an industrial bath containing two additives were characterized by analysing their morphology, structure, microhardness, residual stress and corrosion resistance. Changes in deposit characteristics following the addition of saccharin were also studied. All coating, with or without saccharin, presented a good appearance, good mechanical properties and a high corrosion resistance. Moreover, by varying certain plating conditions it was observed that the deposits maintained their properties over a wide interval of experimental conditions, which suggests their suitability for use in batch bath.
