A coating method for a component with at least one aperture includes providing a component having at least one aperture formed in a surface thereof; additively manufacturing a hollow member on a portion of the surface to define a space above each aperture, the portion of the surface being adjacent to the aperture, the hollow member having an inner peripheral geometry complementary to a peripheral geometry at least one of aperture; applying at least one coating over the surface of the component and around hollow member to form an applied coating having an applied coating thickness; and removing at least a portion of the hollow member to make a top portion of the hollow member coplanar with the applied coating to expose the space through the applied coating; wherein a lower portion of the hollow member remains to define the space through the applied coating.

Manufactured articles, and methods of manufacturing enhanced surface smoothed components and articles. More particularly, surface smoothed components and articles, such as combustor components of turbine engines, having surface treatment conferring reduced roughness for enhanced performance and reduced wear related reduction in part life.
