COMPONENTS WITH COOLING CHANNELS AND METHODS OF MANUFACTURE

摘要

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.

主权项

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 one or more grooves, wherein each groove extends at least partially along the outer surface of the substrate and has a base and a top; a structural coating disposed on at least a portion of the substrate, wherein a surface of the structural coating is faceted in a vicinity of the respective groove, and wherein one or more access holes are formed through the base of a respective groove, to connect the groove in fluid communication with the respective interior space; and an additional coating disposed over at least a portion of the structural coating, wherein the groove(s), the structural coating and the coating together define one or more channels for cooling the component.
