Abstract
A method for repairing an at least externally coated hollow component. The direct mechanical machining of a coated component after use removes the need for a coating-removal and selective hollowing step and a selective repair of cracks, since a design adaptation leads to a component being engineered or used such that it can be used again as a result of external dimensional stipulations.
Claims14
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.
