  • Method of bonding titanium to stainless steel
    Patent number: 8091765
    Abstract: A method of bonding a stainless steel part to a titanium part by heating a component assembly comprised of the titanium part, the stainless steel part, and a laminated titanium-nickel filler material placed between the two parts and heated at a temperature that is less than the melting point of either the stainless steel part or the titanium part. The component assembly is held in intimate contact at temperature in a non-reactive atmosphere for a sufficient time to develop a hermetic and strong bond between the stainless steel part and the titanium part. The bonded component assembly is optionally treated with acid to remove any residual free nickel and nickel salts, to assure a biocompatible component assembly, if implanted in living tissue.
    Type: Grant

    Date of Patent: January 10, 2012

  • Brazing titanium to stainless steel using nickel filler material
    Patent number: 7178710
    Abstract: A method of braze bonding a stainless steel part to a titanium part by heating a component assembly comprised of the titanium part, the stainless steel part, and a very thin substantially pure nickel foil filler material placed between the two parts and heated at a temperature that is greater than the temperature of the eutectic formed between the titanium part and the substantially pure nickel filler material, but that is less than the melting point of either the filler material, the stainless steel part, or the titanium part. The component assembly is held in intimate contact at temperature in a non-reactive atmosphere for a sufficient time to develop a hermetic and strong bond between the stainless steel part and the titanium part. The bonded component assembly is optionally treated with acid to remove any residual free nickel and nickel salts, to assure a biocompatible component assembly for implantation in living tissue.
