New Developments in Zinc Nickel Plating Systems

Dr.-Ing. Max Schlötter GmbH & Co. KG

All alkaline Zinc Nickel electrolytes contain organic amines and breakdown product Cyanide in the electrolyte composition. Therefore Schlötter develops a new anode type for alkaline ZnNi electrolytes: less decomposition products and no CN formation; less additive consumption; higher current efficiency; less voltage.

The newest development is boric acid free and have lower metal concentrations. The process achieve a better performance regarding apply-able current density and is easier for rinse off, what result in better performance regarding post treatment and white spot leaching after storage.
