Zinc corrodes very little in outdoor atmospheres, but under conditions of more than 70% humidity, its corrosion is severe as the corrosion products absorb sufficient water to stimulate further corrosion. In view of the known noncyanide alkaline zinc plating compositions being associated with a low cathode efficiency, or producing deposits which are blistered, pitted or unsuitable for chromating, efforts were made to develop noncyanide zinc electrolytes. Nitrotriacetic acid (NTA) as a complexing agent has not been fully exploited, hence the development of a suitable NTA based bath composition to deposit zinc is discussed in this paper.
