A gas turbine component subject to extreme temperatures and pressures includes a wall (22) defined by opposite first and second surfaces (100,102). An airflow aperture through the wall is defined by an aperture wall surface (106) which extends from a first opening in the first surface to a second opening in the second surface (102). The aperture wall surface is flared at a juncture with the first surface (100), such that the first opening has a greater cross-sectional flow area than the second opening. A high-pressure, high-temperature resitant coating (108) is adhered to the first surface, and adhered to at least a portion of the aperture wall surface. |
