1. A method for repairing an at least externally coated hollow component, wherein the component comprises a substrate, where the substrate comprises at least one layer, where the at least one layer constitutes a metallic and/or ceramic coating, where the substrate optionally comprises cracks, the method comprising:
measuring an interior contour and an exterior contour of the hollow component, comprising a wall thickness, and
stipulating a minimum wall thickness through a design adaptation or a design verification whether a minimum contour having the minimum wall thickness is present, where the minimum contour permits renewed use of an overhauled component having this minimum wall thickness, and
mechanical machining of the component, which comprises the substrate and the coating, until a tolerance contour is obtained, without prior coating removal, and
optionally ablating material of the substrate, to remove cracks.
