A diffusion brazing process for superalloy parts is performed on the one hand by the interposition between the pieces to be joined of a joining layer having a composition close to that of the parts and containing a "fluxing" element, which renders it more readily meltable, and on the other hand, a heat treatment effecting the brazing by the melting of the joining layer and its resolidification, by the diffusion of the flux. The process of the invention is characterized, particularly in view of permitting the use of a joining layer of a greater thickness than that of the layers used in the known diffusion brazing processes, in that said joining layer consists of a mixture of a superalloy powder and an alloy powder containing the flux. |
