摘要： A superalloy component such as a gas turbine engine blade (40) having a ceramic thermal barrier coating (41) is repaired using a textured repair foil (30). A degraded region of the thermal barrier coating is removed (14) and the underlying superalloy material surface is prepared (16) for re-coating. The repair foil is includes a layer of boron-free braze material (34) and a layer of superalloy material (32) having a textured surface (36). The foil is brazed (18) to the prepared surface during a solution heat treatment effective to homogenize the braze (20). A new area of thermal barrier coating (46) is applied over the foil with a bond that is enhanced by the texturing of the foil surface.

摘要： A method of manufacturing a substrate (16) with a ceramic thermal barrier coating (28, 32). The interface between layers of the coating contains an engineered surface roughness (12, 24) to enhance the mechanical integrity of the bond there between. The surface roughness is formed in a surface of a mold (10,20) and is infused by a subsequently cast layer of material (16, 28). The substrate may be partially sintered (76) prior to application of the coating layer(s) and the coated substrate and coating layer(s) may be co-sintered to form a fully coherent strain-free interlayer.

摘要： A component (34A, 34B, 34C) has a core formed of a stack (25, 36) of sheets (20) of material with cutouts (22A) aligned to form passages (38) in the core. An outer casing (29) spans the stack axially (51), brackets at least parts of opposed ends of the stack, and holds the sheets together in axial compression (46). Respective cooperating elements (30, 31) on the casing and the stack may register the casing with respect to the stack. Pins (24) in some sheets may engage holes (23) in adjacent sheets to register the sheets with each other. The casing may be segmented (28A, 28B, 28C). A hoop (66) may be compressed around the segmented casing. A gas turbine fuel injector may be formed of a stack (36) with an inlet element (44) compressed (46) onto the stack by the casing (29).

摘要： A thermal barrier tile (34) with a braze layer (46) co-sintered to a ceramic layer (48), optionally with a layer of MCrAlY bond material (74) disposed there between. The tile can be brazed to a substrate (26) of a component for fabrication or repair of a thermal barrier coating (28). The tile may be fabricated by disposing a first layer of a metal brazing material in a die case (40); disposing a second layer of a ceramic powder on the metal brazing material; and co-sintering the two layers with spark plasma sintering to form the co-sintered ceramic/metal tile. The tile may include an interlocking structural pattern (56) at the ceramic/braze interface, and further may include mirror image contoured edges (70) for interlocking of tiles that are disposed side-by-side. Heights of adjacent tiles (34F, 34G) may be different to improve abradability of the surface.

摘要： Turbine and compressor casing abradable component embodiments for turbine engines, with composite grooves and vertically projecting rows of ridges in planform patterns, establishing upper and lower wear zones. The lower wear zone reduces, redirects and/or blocks blade tip downstream airflow leakage, while the upper wear zone is optimized to minimize blade tip gap and wear by being more easily abradable than the lower zone. An elongated first ridge in the lower wear zone terminates in a continuous surface plateau. A plurality of second ridges or nibs, separated by grooves, project from the plateau, forming the upper wear zone. Each of the second ridges has a planform cross section smaller than the plateau planform cross section and a height smaller than the first ridge height. Some embodiments of the second ridges have spacing, planform cross sections, heights and separating groove dimensions selected for shearing when contacted by turbine blade tips.
