Abstract: A repair patch for use with a turbine seal includes a shim having a first side and an opposite second side and a cloth seal having a first section and a second section. The cloth seal is coupled to the shim, such that the cloth seal is folded over a radial edge of the shim such that the first section substantially covers the first side and the second section substantially covers the second side. The second section includes an extension section that extends from the second side such that at least a portion of the cloth seal overlaps at least a portion of the turbine seal when coupled thereto.

Abstract: A method of welding a superalloy component includes the following sequential steps. A welding step for welding a cavity using a filler metal in an inert atmosphere, where the cavity is located in the component. A covering step for covering the filler metal and a portion of the component with a weld filler layer in the inert atmosphere. The weld filler layer has a greater ductility than material comprising the component and/or material comprising the filler metal. A second covering step for covering the weld filler layer with a braze material, and subsequently performing a brazing operation. A heat treating step heat treats the component.

Abstract: A method for treating a turbine diaphragm and a treated turbine diaphragm are provided. The method includes the step of removing a portion of the turbine diaphragm. The method further includes the step of forming a coupon having a geometry that corresponds to the portion of the turbine diaphragm removed. The method further includes joining the coupon to the turbine diaphragm. At least a portion of the coupon is a pre-sintered preform. The treated turbine diaphragm includes a substrate and a coupon joined to the substrate, wherein at least a portion of the coupon is a pre-sintered preform.

Abstract: A method of repairing a superalloy component includes subjecting the superalloy component, including a repair area, to a phase agglomeration cycle, which includes stepped heating and controlled cooling of the component. The method further includes applying weld material to the repair area to create a weld surface; and covering the weld surface with brazing material. The component is then subjected to a braze cycle to produce a brazed component. The brazed component is cleaned, and the cleaned component is subjected to a restorative heat treatment to restore the microcrystalline structure and mechanical properties of the component.

Abstract: A method of brazing a treatment area of a load-bearing component includes applying a repair material over the treatment area of the component and positioning an induction brazing coil having a geometry corresponding to the treatment area over the repair material and the treatment area. The method further includes heating the repair material utilizing the induction brazing coil to a temperature sufficient to cause at least partial melting of the repair material, thereby effecting a brazed joint between the treatment area and the repair material.
