Hybrid diffusion-brazing process

摘要

A hybrid diffusion-brazing process (300) and hybrid diffusion-brazed article are disclosed. The hybrid diffusion-brazing process (300) includes providing a component (101) having a temperature-tolerant region (105) and a temperature-sensitive region (106), brazing a braze material (103) to the temperature-tolerant region during a localized brazing cycle (100), then heating the component in a furnace (202) during a diffusion cycle (200). The brazing and the heating diffusion-braze the braze material (103) to the component, and the localized brazing cycle (100) is performed independent of the diffusion cycle (200) in the hybrid diffusion-brazing process. The hybrid diffusion-brazed article includes a component (101), and a braze material (103) diffusion-brazed to the component (101) with a filler material (103). The filler material has a melting temperature that is above a tolerance temperature of the component (101).
