The potential use of anodised zirconium as permanent implant has been investigated. Zirconium was anodised at constant potential between 3 and 30 V in H3PO4. Electrochemical assays were conducted in simulated body fluid solution (SBF) in order to evaluate the effect of the surface oxide on the corrosion resistance in vitro after 30 days of immersion. The rupture potential increases when increasing thickness of the anodic surface film. The increase in the barrier effect when increasing anodising potential is also verified by EIS. Anodisation in H3PO4 proved to increase the apatite formation capability of zirconium in a single step. In vivo bone formation was also analysed by implanting the modified materials in Wistar rats. Anodised Zr presents higher corrosion resistance in SBF in all the studied immersion times when compared with non anodised Zr. Additionally, in vivo experiments evidence bone generation and growth in contact with zirconium implants both in the as-received and anodised condition. ; Fil: Gomez Sanchez, Andrea Valeria.
