Abstract: A system includes a gas turbine component having a recessed portion with a recessed surface in a hard-to-weld (HTW) material. The system includes a plate disposed over the recessed portion. The plate has an easy-to-weld (ETW) material. The plate has an outer surface and an inner surface, and the inner surface faces the recessed portion. The system includes a braze material disposed within the recessed portion between the recessed surface and the inner surface of the plate. The braze material is configured to bond the recessed surface of the recessed portion with the inner surface of the plate when the braze material is heated to a brazing temperature. The system includes a filler material disposed on the outer surface of the plate disposed over the recessed portion. Application of the filler material to the outer surface of the plate is configured to heat the braze material to the brazing temperature.

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.

Abstract: A method of protecting a hole in a component during a coating process is disclosed. The method includes: placing a plug in the hole, the plug including a water insoluble core and a water soluble layer surrounding at least a portion of an outer surface of the metal core. A coating is applied over the plug and at least a portion of the component. The component is immersed in water to dissolve the water soluble layer, allowing removal of the water insoluble core. Removal of the coating from over the hole and the water insoluble core from within the hole may follow.

Abstract: A method includes heating a brazing material in a braze chamber of a first component to a braze temperature to melt the brazing material. The brazing material flows from the braze chamber, through at least one internal channel of the first component, and into a braze gap between the first component and a second component to braze the first component to the second component. A brazed article includes a first component having a braze chamber and at least one internal channel extending from the braze chamber to an external surface, a second component having at least one braze surface separated from the external surface of the first component by a braze gap, and a braze material in the braze gap. A braze assembly includes a first component, a second component, and a brazing material in the braze chamber.
