Abstract
A manufacturing method includes providing a substrate with an outer surface and at least one interior space, applying a coating on a portion of the substrate and forming one or more grooves in the coating, wherein each groove extends at least partially along the coating. The method further includes processing at least a portion of the surface of the coating to plastically deform the coating in the vicinity of the top of a respective groove. An additional coating is applied over at least a portion of the surface of the coating. A component is disclosed and includes a substrate, a coating disposed on at least a portion of the substrate, and defining one or more grooves therein, and an additional coating disposed over at least a portion of the coating. The substrate, the coating and the additional coating together define one or more channels for cooling the component.
