Coating methods and a coated substrate

摘要

Coating methods and a coated substrate are provided. The coating method includes providing a component having an aperture formed in a surface thereof, arranging and disposing a hollow member on a portion of the surface to define a hollow space above the aperture corresponding to a shape of the aperture at the surface, applying at least one coating over the surface of the component and the hollow member to form an applied coating having an applied coating thickness, and removing at least a portion of the hollow member to expose the hollow space through the applied coating. The coated substrate includes a component having an aperture formed in a surface thereof, a hollow member arranged and disposed on the surface to define a hollow space above the aperture, and an applied coating over the surface of the component, the hollow space being exposed through the applied coating.

1. A coating method, comprising:
providing a component having an aperture formed in a surface thereof; arranging and disposing a hollow member on a portion of the surface to define a hollow space above the aperture, the portion of the surface being adjacent to the aperture, the hollow member having a geometry complementary to the aperture; applying at least one coating over the surface of the component and the hollow member to form an applied coating having an applied coating thickness; and removing at least a portion of the hollow member to expose the hollow space through the applied coating; wherein a lower portion of the hollow member remains to define the hollow space through the applied coating.
