Abstract: A method of forming micro channels in a thermal barrier coating includes placing a brazing tape on a substrate. The brazing tape has a first side and a second side with a plurality of ceramic members attached thereto. The first side is placed in contact with the substrate. A brazing step brazes the brazing tape to the substrate. An applying step applies a bond coat to the second side of the brazing tape. Another applying step applies a thermal barrier coating (TBC) onto the bond coat. A removing step removes the plurality of ceramic members by exposing the plurality of ceramic members to a ceramic solvent. A plurality of micro channels are formed in the thermal barrier coating by voids left from the plurality of ceramic members.

Abstract: A method for repairing a part and the resulting is disclosed. The method includes positioning a plug having an inner braze element coupled thereto into a cavity defined by an internal surface of a component. The cavity has a circular cross-section at the external surface of the component. The plug completely fills the circular cross-section and the inner braze element is within the cavity. A braze paste is positioned at least partially around the plug at the external surface. The component is positioned such that the inner braze element is above the plug. The component is subjected to a thermal cycle to melt the inner braze element around the plug, completely sealing the cavity by forming a metallurgical bond with the plug and the internal surface of the component. During the thermal cycle the braze paste is melted to form a metallurgical bond with the plug and external surface.

Abstract: A closure element for an internal passage in a component, and a related method and turbine blade or nozzle are disclosed. The closure element includes a spherical body made of a first superalloy, and a plurality of extensions extending from a surface of the spherical body. The plurality of extensions made of the same, similar or different material other than the first superalloy. Subjecting the component to at least one thermal cycle causes a braze material to form a metallurgical bond with the spherical body, the plurality of extensions and the passage wall to seal the internal passage.
