    Patent number: 5211663
    Abstract: Passivated implants and passivation methods that provide superior corrosion resistance and surface performance characteristics as compared to conventional nitric acid passivation are disclosed. The method uses either the spontaneous or galvanic passivation of metallic prosthetic implants in aqueous alkali salt solutions containing non-aggressive oxyanions to produce a thin and uniform passive coating on the metal implant, thereby rendering the implant more stable in the biological environment.
