Repair methods for cooled components

A method for repairing a component (100) is provided, where the component has a substrate (110) comprising an outer surface (112) and an inner surface and defining one or more grooves. Each groove extends at least partially along the outer surface (112) of the substrate (110). The component further...

Beschreibung
Zusammenfassung:	A method for repairing a component (100) is provided, where the component has a substrate (110) comprising an outer surface (112) and an inner surface and defining one or more grooves. Each groove extends at least partially along the outer surface (112) of the substrate (110). The component further includes a structural coating (150), a bond coating (152), and a thermal barrier coating (154). The groove(s) and the structural coating (150) define one or more channels (130) for cooling the component (100). The repair method includes removing the thermal barrier (154) and bond coatings (152), removing at least a portion of the structural coating (150) in a vicinity of a damaged portion of the component (100), performing a repair operation on the damaged portion of the component (100), applying a structural coating (150) at least in a vicinity of the repaired portion of the component (100), and applying a bond coating (152) and a thermal barrier coating (154). Additional repair methods are also provided.
