Abstract
A method is disclosed during which a substrate is provided. Braze powder is deposited with the substrate using an additive manufacturing device. The braze powder is sintered together and to the substrate during the depositing of the braze powder to provide the substrate with sintered braze material. The substrate and the sintered braze material are heated to melt the sintered braze material and diffusion bond the sintered braze material to the substrate.
Claims20
A method, comprising:
- providing a substrate;
- depositing braze powder with the substrate using an additive manufacturing device, the braze powder sintered together and to the substrate during the depositing of the braze powder to provide the substrate with sintered brazed material;
- and
- heating the substrate and the sintered braze material to melt the sintered braze material and diffusion bond the sintered braze material to the substrate.

A method, comprising:
- providing a substrate comprising metal;
- directing braze powder to the substrate through a nozzle;
- sintering the braze powder to the substrate using an energy beam to provide sintered braze material;
- and
- subjecting the substrate and the sintered braze material to a heat cycle to melt the sintered braze material and diffusion bond the sintered braze material to the substrate.

A method, comprising:
- providing a substrate;
- sintering braze powder to the substrate using an additive manufacturing device to provide the substrate with sintered brazed material;
- and
- subsequent to the sintering of the braze powder, subjecting the substrate and the sintered braze material to a heat cycle to melt the sintered braze material and diffusion bond the sintered braze material to the substrate.
