Abstract

The invention at hand relates to a method for processing and repairing a metal component with at least one finished or nearly finished partial component surface and at least one working surface to be further processed by means of an electrochemical treatment process and abutting the at least one finished or nearly finished partial component surface, with the process comprising the following steps: a) application of an electrically conductive layer on at least one area of the at least one finished or nearly finished partial component surface abutting the working surface to be processed, with the layer containing a metal or a metal alloy that has a similar or the same as, or a desiredly different electrochemical erosion behavior than the metal component; and b) electrochemical treatment of the working surface and of the layer, with the layer being completely or nearly completely eroded. The invention moreover relates to a component of a gas turbine or of a high or low pressure compressor.
