Abstract
Process for connecting a honeycomb core material to facing sheets or plates by liquid interface diffusion, when the core and sheets or plates are Ti (alloy), comprises depositing successive laminar layers of two metals which form a diffusion bridge at the marginal surface of the core, siting the corresponding surfaces to be connected with the bridge material between them, submitting the surfaces to a positive pressure great enough to hold their position and alignment and, while the surfaces are held in a protective atmosphere the temp is raised so as to (a) encourage atomic diffusion in the laminar layers and between the bridge layer and the Ti (b) encourage formation of a molten mass of the eutectic alloy formed by the diffusion and (c) to maintain the temp at a predetermined time after the eutectic mass has solidified to dilute the bridge material and the Ti in the liaison zone by solid state diffusion between them. The laminar metallic layers are Ni and Cu and are of the same weight. This gives rapidly formed diffusion joints with the advantages arising from both liquid and solid state diffusion.
