Abstract
Disclosed is a method of treating the surface of an electrically conducting substrate surface wherein a tool comprising an ion-conducting solid material is brought into contact at least in some areas with the substrate surface. The tool conducts the metal ions of the substrate and an electric potential is applied so that an electrical potential gradient is applied between the substrate surface and the tool in such a manner that metal ions are drawn from the substrate surface or deposited onto the substrate surface by means of the tool.
