摘要：The invention provides novel passivated implants and passivation methods thatprovide superior corrosion resistance and surface performance characteristics ascompared to conventional nitric acid passivation. The method uses either the
spontaneous or galvanic passivation of metallic prosthetic implants in aqueous alkali saltsolutions containing non-aggressive oxyanions to produce a thin and uniform passivecoating on the metal implant, thereby rendering the implant more stable in thebiological environment.
