A method for producing a zinc-based coating for a component, zinc-based coating produced by such a method, as well as component with at least partially such a zinc-based coating

摘要

The invention relates to a method for producing a zinc-based coating (3) for a component (5), in particular a body component, wherein the coating (3) comprises an alloy (7), the alloy (7) comprising zinc and manganese, and wherein the coating (3) is deposited by an electrolytic process, in particular a galvanostatic process, by means of a pulse current from an electrolyte solution. The method is characterized in that the pulse current has an average current density of 0.01 to 0.02 A / cm ² , a maximum current density of 0.025 to 0.15 A / cm ² , and a cathodic pulse duration of 1 to 50 ms , and the alloy (7) has a manganese content of 5 to 25% by weight.
