COMPONENTS WITH ASYMMETRIC COOLING CHANNELS AND METHODS OF MANUFACTURE
First Claim
1. A method of fabricating a component comprising a substrate having an outer surface and an inner surface, wherein the inner surface defines at least one interior space, the fabrication method comprising:
- forming at least one groove in the outer surface of the substrate, wherein each groove extends at least partially along the outer surface of the substrate and has an asymmetric cross-section;
forming at least one access hole in the substrate, wherein each access hole connects the respective groove in fluid communication with the respective interior space; and
disposing a coating over at least a portion of the surface of the substrate, such that the groove(s) 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 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.
