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.
