Abstract
Disclosed is a method for the production of electroplated components. In the disclosed method, an edge layer of a component to be coated is subjected to a mechanical treatment in which the edge layer is deformed at least in portions, consequently the structure of the edge layer being modified at least in portions and hydrogen traps being produced in the modified portions of the edge layer.

A method for producing electroplated components, in which
- a) an edge layer of a component to be coated is subjected to a mechanical treatment, in which the edge layer is deformed at least in portions, consequently the structure of the edge layer being modified at least in portions and, in the modified portions of the edge layer, hydrogen traps being produced, and
- b) at least on a part of the surface of the mechanically treated edge layer of the component to be coated, a coating is electrodeposited, hydrogen being released during the electrodeposition which penetrates into the mechanically treated edge layer at least partially,
- the hydrogen traps produced in the modified portions of the edge layer essentially binding the totality of the hydrogen penetrating into the mechanically treated edge layer during the electrodeposition in step b).
