Abstract

The invention relates to a coating method for a workpiece, including the following method steps: a) applying a coating liquid to the workpiece, wherein the coating liquid comprises an ionic liquid containing ions of at least one element, b) electrochemically depositing a layer of the at least one element from the coating liquid on the workpiece, c) removing the workpiece from the coating liquid, d) removing excess coating liquid from the workpiece. In order to suggest an industrially suitable coating process, particularly for workpieces having at least a partial metal surface, using stable, durable baths, it is provided that the temperature of the workpiece is set such that the temperature of the coating liquid deviates by no more than 10° C. from a predetermined set temperature during the coating process
