Abstract:
1. A method of coating a component comprising a substrate, wherein one or more grooves are formed in and extend at least partially along a surface of the substrate, the method comprising: depositing a coating over at least a portion of the surface of the substrate, wherein each groove has an opening defined at an outer surface of the substrate and wherein the coating comprises one or more layers, wherein at least one of the layers comprises a structural coating having a non-homogenous microstructure and defining one or more permeable slots, such that the structural coating does not completely bridge each of the one or more grooves, and is deposited at one or more angles including an angle α wherein α is in a range of about 10-85 degrees relative to a surface normal of the substrate, wherein the step of depositing the coating provides for substantial sealing of the opening of each groove at the outer surface of the substrate, and wherein the one or more grooves formed in the substrate and the structural coating together define one or more channels within the substrate for cooling the component.
