The corrosion of the surfaces of metallic implants is a very aggressive process, which can cause inflammation and deposition of metal in the surrounding live tissue. Prevention of corrosion and improvement of the functional characteristics of different coatings for application on implant surfaces is essential. Niobium and tantalum anodic oxides of optimal thickness have enabled the manufacture of a new generation of bioengineering products displaying minimal corrosion.
