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.

1. A manufacturing method comprising: providing a substrate with an outer surface and at least one interior space;applying a coating on at least a portion of the substrate;forming one or more grooves only within the coating wherein each groove extends at least partially along an outer surface of the substrate and has a base, a top and a gap present across the top of the groove;forming one or more cooling supply holes through the base of a respective groove wherein each of the one or more cooling supply holes is formed at a 45° to 90° angle relative to the base of a respective groove, to connect the groove in fluid communication with the respective interior space;processing at least a portion of a surface of the coating so as to plastically deform the coating at least in a vicinity of the top of a respective groove, such that a gap across the top of the groove is reduced; andapplying one or more additional coatings over at least a portion of the surface of the coating, wherein the substrate, the coating and the additional coating define one or more enclosed channels for cooling a component. 2. The manufacturing method of claim 1, wherein the step of forming one or more grooves further comprises forming at least a portion of the one or more grooves in a portion of the substrate. 3. The manufacturing method of claim 1, wherein each groove is formed using one or more of an abrasive liquid jet, plunge electrochemical machining (ECM), electric discharge machining (EDM) with a spinning electrode (milling EDM), and laser machining. 4. The manufacturing method of claim 1, wherein processing the surface of the coating comprises performing one or more of shot peening the surface, water jet peening the surface, flapper peening the surface, gravity peening the surface, ultrasonic peening the surface, burnishing the surface, low plasticity burnishing the surface, and laser shock peening the surface, to plastically deform the coating at least in the vicinity of the groove. 5. The manufacturing method of claim 4, wherein the processing introduces a plurality of surface irregularities in the surface of the coating. 6. The manufacturing method of claim 4, wherein processing the surface of the coating comprises shot peening the surface. 7. The manufacturing method of claim 6, wherein shot peening the surface includes peening particles having a diameter greater than the gap across the top of the one or more grooves. 8. The manufacturing method of claim 1, wherein the gap across the top of the groove is in a range of about 0.2-1.0 mm prior to processing the surface of the coating, and wherein the gap across the top of the groove is in a range of about 0-0.4 mm after the surface of the coating has been processed. 9. The manufacturing method of claim 1, wherein the additional coating comprises one or more of an outer structural coating layer, a bond coating and a thermal barrier coating. 10. The manufacturing method of claim 1, wherein the additional coating comprises an outer structural coating layer. 11. The manufacturing method of claim 1, wherein the step of processing the surface of the coating facets the coating in a vicinity of the groove. 12. A manufacturing method comprising: providing a substrate with an outer surface and at least one interior space;applying a structural coating on at least a portion of the substrate;forming one or more grooves only within the structural coating wherein each groove extends at least partially along an outer surface of the substrate and has a base and a top and a gap present across the top of the groove;forming one or more cooling supply holes through the base of a respective groove, wherein each of the one or more cooling supply holes is formed at a 45° to 90° angle relative to the base of a respective groove to connect the groove in fluid communication with the respective interior space;processing at least a portion of a surface of the structural coating so as to plastically deform the structural coating at least in a vicinity of the top of a respective groove and facet the surface of the structural coating in a vicinity of the groove, such that a gap across the top of the groove is reduced; andapplying one or more additional coatings over at least a portion of the surface of the structural coating, wherein the substrate, the structural coating and the additional coating define one or more enclosed channels for cooling a component. 13. The manufacturing method of claim 12, wherein the step of forming one or more grooves further comprises forming at least a portion of the one or more grooves in a portion of the substrate. 14. The manufacturing method of claim 12, wherein processing the surface of the structural coating comprises performing one or more of shot peening the surface, water jet peening the surface, flapper peening the surface, gravity peening the surface, ultrasonic peening the surface, burnishing the surface, low plasticity burnishing the surface, and laser shock peening the surface, so as to deform the coating at least in a vicinity of the top of a respective groove and facet the surface of the structural coating adjacent at least one edge of the groove. 15. The manufacturing method of claim 14, wherein processing the surface of the structural coating comprises shot peening the surface, and wherein the shot peening introduces a plurality of surface irregularities in the surface of the structural coating. 16. The manufacturing method of claim 15, wherein shot peening the surface includes peening particles having a diameter greater than the gap across the top of each of the one or more grooves. 17. The manufacturing method of claim 12, wherein the additional coating comprises one or more of an outer structural coating layer, a bond coating and a thermal barrier coating.
