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