Abstract
Operating conditions for zinc and nickel codeposition from chloride baths were studied in order to obtain alloys containing up to 20% nickel. Satisfactory deposits were produced at 50°C using current densities ranging from 5 to 20 mA cm−2 and nickel to zinc ratios ranging from 6.8 to 37.5%.
Under the conditions studied, an empirical relationship was deduced in order to calculate the nickel percentage in the deposit from baths of prefixed composition using a given current density. Deposits having a nickel concentration lower than 11% were found to comprise the δ and γ phases, while at higher nickel concentration (up to 20%), the alloys showed only the γ phase structure, with preferred orientation (442) and (600) and excellent microhardness and corrosion resistance properties.
