초록 ▼

A manufacturing method includes forming one or more grooves in a component that comprises a substrate with an outer surface. The substrate has at least one interior space. Each groove extends at least partially along the substrate and has a base and a top. The manufacturing method further includes applying a structural coating on at least a portion of the substrate and processing at least a portion of the surface of the structural coating so as to plastically deform the structural coating at least in the vicinity of the top of a respective groove, such that a gap across the top of the groove is reduced. A component is also disclosed and includes a structural coating disposed on at least a portion of a substrate, where the surface of the structural coating is faceted in the vicinity of the respective groove.

대표청구항 ▼

1. A component comprising: a substrate comprising an outer surface and an inner surface, wherein the inner surface defines at least one interior space, wherein the outer surface defines a plurality of grooves, wherein each groove extends at least partially along the outer surface of the substrate and has a base and a top, each base is spaced from the outer surface and each top is in the outer surface and defines a groove opening in the outer surface of the substrate, and one or more access holes are formed though the base of a respective groove, to connect the groove in fluid communication with the respective interior space;a first coating, having an outer surface and an inner surface, the inner surface disposed on and in contact with at least a portion of the outer surface of the substrate, wherein the coating comprises a plurality of coating openings, each coating opening above a respective groove opening of the substrate, the outer surface of the first coating is faceted toward each groove base in a vicinity of each groove adjacent at least one edge of the groove opening; andan optional second coating disposed over at least a portion of the outer surface of the first coating, wherein spaces formed between the inner surface of the first coating and the groove bases and the optional second coating together define a plurality of channels for cooling the component. 2. The component of claim 1, wherein a plurality of surface irregularities are formed in the outer surface of the first coating in the vicinity of each groove. 3. The component of claim 1, wherein the second coating comprises one or more of a bond coating and a thermal barrier coating. 4. The component of claim 1, wherein an outer surface of the second coating is faceted toward each groove base in the vicinity of each groove. 5. The component of claim 1, wherein each groove narrows at the respective top thereof, such that each groove comprises a re-entrant shaped groove, and each channel comprises a re-entrant shaped channel. 6. The component of claim 1, wherein the second coating comprises a plurality of gaps at positions corresponding to the groove openings.
