Patent number: 4818625Abstract: Hydrogenated boron-silicon alloy films having unexpected properties permitting in one embodiment the bonding together of metal and ceramic substrates by coating the surfaces to be bonded with the film mating the surfaces and heat treating the mated surfaces to expell hydrogen therefrom and to react to resulting boron-silicon alloy film with the substrates to form a liquid reaction product which forms a surface bond with the substrates or is at least partially absorbed in the substrates. In another embodiment, at least one surface of an intermetallic compound formed from elements selected from groups III and V of the periodic table is sealed against structural degradation by forming on the surface a solid boron-silicon-hydrogen alloy film. In still another embodiment, metal and organic resin substrates are protected against attack by water vapor, dissociated oxygen and molecular oxygen by forming a solid boron-silicon-hydrogen alloy film on the substrates.Type: GrantFiled: March 23, 1987Date of Patent: April 4, 1989Assignee: Lockheed Missiles & Space Company, Inc.Inventors: Henry W. Lavendel, John C. Robinson
