<p>A method of fabricating a component (100) is provided. The method includes depositing a structural coating (54) on an outer surface (112) of a substrate (110), where the substrate (110) has at least one hollow interior space (114). The method further includes forming one or more grooves (132) in the structural coating (54). Each groove has a base (134) and extends at least partially along the substrate. The method further includes depositing at least one additional coating (56, 59) over the structural coating and over the groove(s), such that the groove(s) and the additional coating together define one or more channels (130) for cooling the component. The method further includes forming one or more access holes (140) through the base (134) of a respective groove, to connect the respective groove in fluid communication with the respective hollow interior space (114), and forming at least one exit hole (142) through the additional coating (56, 59) for each channel, to receive and discharge coolant from the respective channel. A component (100) with cooling channels (130) formed in a structural coating (54) is also provided.</p> |
