A conformal seal ( 20 ) for sealing air flow between a cooling airflow path and a hot gas flow path within a combustion turbine engine. The conformal seal ( 20 ) may be fitted within cooperating side slots of adjacent vane segments ( 10 ) within the combustion turbine engine. The conformal seal ( 20 ) may include an elongated metallic substrate ( 22, 40 ) forming an upper surface and a lower surface. A conformal coating ( 26, 44 ) may be deposited over one or both surfaces of the substrate ( 22, 40 ). The conformal coating ( 26, 44 ) may be deposited to a depth so that a point contact between the conformal coating ( 26, 44 ) and respective interior walls of the side slots wears the conformal coating ( 26, 44 ) to establish surface area contact there between. The surface area contact improves a sealing function between the conformal coating ( 26, 44 ) and the respective interior walls during operation of the combustion turbine engine.
