Patent GB-2067532-A (GB)
Title: Stopoff composition and method of making diffusion bonded structures
IPC: B23K20/18
Filed: 1980-01-14
Abstract: A method for fabricating superplastically formed/diffusion bonded structures wherein metal blanks of a titanium alloy are joined at selected areas by diffusion bonding and expanded superplastically to form a sandwich or integrally stiffened structure, comprises treating the metal blanks in selected areas with a stopoff material to prevent bonding at those areas during diffusion bonding and to permit forming or shaping at the same areas during superplastic forming by the introduction of gas through ducts to expand the metal into die cavities. The stopoff composition provided for this purpose, is in the form of yttria of particle size coarser than 5 microns, in a suitable volatilizable organic liquid vehicle, comprising a resin binder e.g. acrylic resin. The stopoff composition is inert to reactive metals such as titanium at the high diffusion bonding temperatures, and permits relatively low breakthrough pressure-time product during superplastic forming, thereby preventing excessive strain or rupture of the metal through non-superplastic deformation.
