Abstract

Zinc electrodeposits are widely used to protect iron and steel from corrosion. Zinc coatings are presently obtained from chloride, sulfate, mixed chloride and sulfate, cyanide and non-cyanide alkaline baths. Atmospheric corrosion is associated with the use of chloride electrolytes. The use of additives, low cathode efficiency and the costly effluent treatment discourage the use of non-cyanide alkaline zinc plating baths. Hence, a better quality zinc plating electrolyte is necessary. In this paper, the authors present a detailed investigation of zinc plating from non-cyanide based acetate electrolytes and the effect of thiamine hydrochloride and gelatin as additives to produce quality bright deposits. The bath and deposit characteristics of acetate-based zinc plating was studied and the results are presented.
