Abstract
1438842 Brazing and welding ROHR INDUSTRIES Inc 21 Aug 1973 39385/73 Heading B3R In liquid interface diffusion bonding of articles of titanium or titanium based alloy an alloy of nickel and copper or layers of copper, nickel and copper in that order, or an alloy of nickel, copper and silver or layers of nickel, copper, silver, copper and nickel in that order are deposited as a diffusion bridge between the articles, the assembly is heated to form by solid state diffusion a eutectic comprising titanium, and the diffusion bridge, the eutectic melting and then as a result of further diffusion, solidifiying, the temperature is maintained to cause further solid phase diffusion and then the assembly is cooled. In an embodiment of bonding a sheet to a honeycomb core or a sheet to a sheet, the parts to be joined both being of titanium or titanium based alloy, an alloy of nickel, copper and silver or layers, viz nickel, copper, silver, copper and nickel, are deposited on at least one of the parts by, e.g. brushing, electroplating, vapour deposition or powder flame spray to provide 1-5 grams. /square foot of honeycomb core or 6-12 grams./square foot for sheet material the amounts of the metals are 38-45% nickel, 38-45% copper and 10-24% silver. The parts are assembled and in a vacuum are heated at 100‹F./min.to 1400‹ F., at 20‹ F./min to 1600‹ F. when a copper/silver mush forms at 2‹F/min. to 1700-1750‹ F. when the titanium, nickel and copper eutectic composition is reached by solid state diffusion and the eutectic melts. Continuing diffusion produces enriched titanium composition and solidification of the alloy. Further heating at 1700-1750‹ F. causes solid state diffusion at the interfaces and finally the assembly is cooled, the final cooling taking place in inert atmosphere. In an alternative embodiment the coated layers are of copper, nickel and copper (40-60% nickel 60-40% copper). In both embodiments the heating steps are the same. The assembly is held at 1700‹ F. for 90 minutes.
