Abstract: A method of fabricating a component is provided. The component includes a substrate having an outer surface and an inner surface, where the inner surface defines at least one interior space. The fabrication method includes forming at least one groove in the outer substrate surface. Each groove extends at least partially along the outer substrate surface and has an asymmetric cross-section. The method further includes forming at least one access hole in the substrate. Each access hole connects the respective groove in fluid communication with the respective interior space. A coating is disposed over at least a portion of the substrate surface, such that the groove(s) and the coating together define one or more channels for cooling the component. A component is also disclose and has at least one groove with an asymmetric cross-section.

Abstract: A component is disclosed. The component comprises a substrate comprising an outer surface and an inner surface, where the inner surface defines at least one hollow, interior space, where the outer surface defines one or more grooves, and where each of the one or more grooves extends at least partially along the surface of the substrate and has a base. One or more access holes extend through the base of a respective groove to place the groove in fluid communication with respective ones of the at least one hollow interior space. The component further comprises a coating disposed over at least a portion of the substrate surface, where the coating comprises one or more layers. At least one of the layers defines one or more permeable slots, such that the respective layer does not completely bridge each of the one or more grooves. The grooves and the coating together define one or more channels for cooling the component.

Abstract: A method of fabricating a component is provided. The component includes a substrate that has at least one interior space. The method includes forming one or more grooves in the component. Each groove extends at least partially along an outer surface of the substrate and narrows at an opening thereof, such that each groove is re-entrant shaped. A cross-sectional area A of each groove is in a range of about 2 to about 3 times an area R=W*D, where W is the width of the opening and D is the depth of the re-entrant-shaped groove. Components with grooves formed in the substrate and components with grooves formed at least partially in a structural coating are also provided.
