A manufacturing method includes providing a substrate with an outer surface and at least one interior space, selectively deposited a coating on a portion of the substrate to form a selectively deposited coating having one or more grooves formed therein. The method further includes processing at least a portion of the surface of the selectively deposited coating to plastically deform the selectively deposited 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 selectively deposited coating. A component is disclosed and includes a substrate, a selectively deposited coating disposed on at least a portion of the substrate, and defining one or more grooves therein, and an additional coating disposed over the selectively deposited coating. The substrate, the selectively deposited coating and the additional coating defining one or more channels for cooling the component.

1. A manufacturing method comprising: providing a substrate with a continuous outer surface and at least one interior space;selectively depositing a coating on at least a portion of the continuous outer surface to define one or more grooves in the coating wherein each groove extends at least partially along the coating;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 respective 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 one or more additional coatings define one or more channels for cooling a component. 2. The manufacturing method of claim 1, wherein selectively depositing a coating on at least a portion of the substrate includes selectively depositing the coating using one of a screen and a mask having defined therein a pattern and positioned between the substrate and a source of the coating. 3. The manufacturing method of claim 1, further comprising machining the deposited coating and a portion of the substrate to further define the one or more grooves. 4. The manufacturing method of claim 3, wherein the step of machining includes 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. 5. The manufacturing method of claim 1, wherein processing the surface of the selectively deposited 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 respective groove. 6. The manufacturing method of claim 5, wherein the processing introduces a plurality of surface irregularities in the surface of the selectively deposited coating. 7. The manufacturing method of claim 5, wherein processing the surface of the selectively deposited coating comprises shot peening the surface. 8. The manufacturing method of claim 7, wherein shot peening the surface includes peening particles having a diameter greater than the gap across the top of the one or more grooves. 9. The manufacturing method of claim 1, wherein the gap across the top of the respective 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 respective groove is in a range of about 0-0.4 mm after the surface of the coating has been processed. 10. The manufacturing method of claim 1, wherein the one or more additional coatings comprises one or more of an outer structural coating layer, a bond coating and a thermal barrier coating. 11. A manufacturing method comprising: providing a substrate with an outer surface and at least one interior space;selectively depositing a coating on at least a portion of the substrate to define one or more grooves in the coating wherein each groove extends at least partially along the coating;machining the coating and a portion of the substrate to further define the one or more grooves;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 and facet the surface of the coating in a vicinity of the respective groove, such that the gap across a top of the respective 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 one or more additional coatings define one or more channels for cooling a component. 12. The manufacturing method of claim 11, wherein selectively depositing a coating on at least a portion of the substrate includes selectively depositing the coating using one of a screen and a mask having defined therein a pattern and positioned between the substrate and a source of the coating. 13. The manufacturing method of claim 11, 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, so as to deform the coating at least in a vicinity of the top of a respective groove and facet the surface of the coating in a vicinity of the respective groove, wherein said vicinity is adjacent to at least one edge of the respective groove. 14. The manufacturing method of claim 13, wherein processing the surface of the selectively deposited coating comprises shot peening the surface, and wherein the shot peening introduces a plurality of surface irregularities in the surface of the coating. 15. The manufacturing method of claim 14, 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. 16. The manufacturing method of claim 11, wherein the one or more additional coatings comprises one or more of an outer structural coating layer, a bond coating and a thermal barrier coating.
