A method of bonding a ceramic part to a metal part by heating a component assembly including the metal part, the ceramic part, and a thin essentially pure interlayer material placed between the two parts heated at a temperature that is greater than the temperature of the eutectic formed between the metal part and the interlayer material, but that is less than the melting point of the interlayer material, the ceramic part or the metal part is disclosed. 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 ceramic part and the metal part. The bonded assembly is optionally treated with acid to remove any residual free nickel and nickel salts to assure a biocompatible assembly for implantation in living tissue.
