ABSTRACT:
In the electrodeposition of iron-zinc alloy coatings, a lustrous, adherent iron-zinc coating containing 10-20% iron is achieved over a current density range of 400-1600 amps/ft.sup.2 and line speeds of 100-500 ft/min. by employing an electrolyte maintained at a temperature of 130.degree. to 160.degree. F. which contains FeCl.sub.2, ZnCl.sub.2, KCl, K.sub.2 SO.sub.4, a chelating agent such as citric acid, and a minor amount of an adduct composed primarily of polyalkylene glycols.
