Abstract
A liquid interface diffusion bonded composition comprises a metal honeycomb core such as a nickel-alloy honeycomb core and a nickel-alloy facing sheet bonded thereto. The composition and method of this invention are useful in applications where high strength, heat resistant materials are required, such as in aircraft and aerospace-related structures. The composition is prepared by a method comprising: (a) providing a nickel-alloy honeycomb core having a mating surface and a nickel-alloy facing sheet having a mating surface; (b) placing together the honeycomb core mating surface and the facing sheet mating surface, and providing therebetween a metal foil comprising nickel, zirconium, and at least one additional metal selected from the group consisting of titanium, niobium, and chromium; (c) subjecting the mating surfaces and metal foil therebetween to sufficient positive pressure to maintain position and alignment for joining; and (d) heating the mating surfaces and metal foil therebetween in a protective atmosphere for at least 2 hours to a temperature sufficient to cause melting between the metal foil and mating surfaces of the facing sheet and honeycomb core.
