Abstract
A method of manufacturing a component is provided. The method includes forming one or more grooves in an outer surface of a substrate. Each groove extends at least partially along the surface of the substrate and has a base, a top and at least one discharge point. The method further includes forming a run-out region adjacent to the discharge point for each groove and disposing a coating over at least a portion of the surface of the substrate. The groove(s) and the coating define one or more channels for cooling the component. Components with cooling channels are also provided.
Claims12
A component comprising:
- a substrate comprising an outer surface and an inner surface, wherein the outer surface defines one or more grooves and one or more run-out regions, wherein each groove extends at least partially along the outer surface of the substrate and has a base and at least one discharge point, and wherein each run-out region is adjacent to the respective discharge point for a respective groove;
- and
- a coating disposed over at least a portion of the outer surface of the substrate, such that the one or more grooves and the coating together define one or more channels for cooling the component and wherein the coating does not bridge the one or more run-out regions, such that each run-out region forms a film hole for the respective groove.
