Abstract
An assembly for a dual-walled component of a gas turbine engine and methods of forming and repairing a dual-walled component. The assembly includes a cold section part having an outer surface that defines a plurality of impingement apertures, a hot section part including a pre-sintered preform, the hot section part positioned over the outer surface of the cold section part, and a plurality of support structures including the pre-sintered preform, the plurality of support structures positioned between the hot section part and the cold section part, the plurality of support structures separating the hot section part from the cold section part to define at least one cooling channel therebetween.
Claims20
A dual-walled component for a gas turbine engine, the dual-walled component comprising:
- a cold section part comprising an outer surface;
- a hot section part positioned over the outer surface of the cold section part;
- and
- a plurality of support structures positioned between and separating the hot section part from the cold section part to define at least one cooling channel therebetween,
- wherein a portion of the hot section part and a portion of the plurality of support structures comprises particles of a high-melt metal alloy and a sintered low-melt braze material,
- wherein at least a portion of the sintered low-melt braze material of each of the portions of the hot section part and the plurality of support structures is diffused into the particles of the high-melt metal alloy, and
- wherein at least a portion of the sintered low-melt braze material of the portion of the plurality of support structures is diffused into the cold section part.
