Excellent bonds between usually-brazed metals are obtained, without brazing or soldering alloys, by initially oxidizing the surfaces to be bonded and then bonding in a reducing atmosphere at a temperature below the melting point of either metal. If the metals form a eutectic, bonding will be carried out above the eutectic temperature. It is believed that the oxidation-reduction cycle produces a perfectly clean or nascent surface which facilitates bonding. Yields are improved by initially providing a very thin plated coating of silver, copper or nickel, or combinations thereof, on one workpiece.
