<p>A method for joining rhenium to columbium and columbium based alloys that minimizes the formation of brittle intermetallics. First, a layer of ruthenium is applied to both the rhenium and columbium and then heated until the ruthenium diffuses with the rhenium and columbium respectively. A braze foil is placed between the two outer ruthenium layers and the assembly is heated in a range of 50 °C to 100 °C above the liquidus of the braze, thereby joining the rhenium to the columbium. Alternatively, the ruthenium coated surfaces are placed in contact and diffused together under a compressive load.</p> |
