A method for providing a film cooled article is disclosed. A metallic article is provided having first and second wall surfaces and a cooling hole. The cooling hole includes a metering hole that extends from an inlet at the second wall surface to an outlet at the first wall surface. The method further includes exposing the first wall surface of the metallic article, applying a thermal barrier coating overlying the first wall surface and at least partially covering the outlet, boring through an outer surface of the applied thermal barrier coating to expose the metering hole, removing the thermal barrier coating from a trough portion of the outlet formed in the metallic article and forming a trough region in the thermal barrier coating that extends from the trough portion of the outlet formed in the metallic article to be flush with the outer surface of the thermal barrier coating.
