The present invention is related to a membrane anode system for electrolytic zinc-nickel alloy deposition, a method for electrolytic deposition of a zinc-nickel alloy layer on a substrate to be treated using a membrane anode system, and the use of a membrane anode system for acid or alkaline electrolytic deposition of a zinc-nickel alloy layer on a substrate to be treated by such a method.

Membrane anode system for electrolytic zinc-nickel alloy deposition

A method for depositing a zinc-nickel alloy on a substrate, including:

Method and system for depositing a zinc-nickel alloy on a substrate

The present invention is related to a method for electrolytically depositing a zinc-nickel alloy layer on a substrate, wherein the method comprises an interrupting of the execution of the electrolytical deposition of a zinc-nickel alloy layer on the surface of a substrate by terminating applying the current from the external current source to each of the soluble zinc anode(s) and to each of the soluble nickel anode(s); and wherein afterwards at least one soluble zinc anode, which is remaining in the electrolysis reaction container, is electrically connected by an electrical connection element to form an electrical connection to at least one soluble nickel anode, which is remaining in the electrolysis reaction container, for at least a part of the defined period of time in which no current from the external current source is applied to each of the soluble zinc anode(s) and to each of the soluble nickel anode(s).
