This connection by superplastic forming and continuous diffusion of the complex structures.

摘要

The method of forming a structural unit using the superplastic forming and the connection by diffusion comprises: the selection of at least two couches2, 4 of a material suitable for the diffusion bonding and superplastic forming the coating material by means of selective locking of at least one of the surfaces of said layers which are face to face of a manner that the surfaces6, 8 coated of material of the stop can form the reinforcing members raised in locations predetermined, the selective application of the material of stoppage in order to form a coating on at least one of the surfaces12, 14 of a couche10 of manner to avoid the formation of zones of weakness which are adjacent to the reinforcing members raised, the formation of a sandwich construction of said layers, and to the submission of the sandwich construction to the steps of the diffusion bonding and superplastic forming.
