Abstract

Nanotube surface topography modification is becoming a promising topic given the interest in increasing the implant osseointegration rate. In this work a nanotube oxide layer was obtained on Ti-35Nb-10Ta and Ti6Al4V ELI alloys by an anodic oxidation process using an electrolyte containing 1 M H3PO4 and 08 w.t. % NaF at room temperature. This study focuses on analyzing the electrochemical behavior of the interface Ti alloy/nanotube. Conventional electrochemical techniques such as open circuit potential (OCP) electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization were perform in 1 M NaCl saline solution. The morphology of the nanotube surfaces was studied by means of a Field Emission Scanning Electron Microscopy (FESEM). EIS data of both substrates and anodized alloys were fitted to different equivalent circuits. From these results we conclude that the Ti35Nb10Ta alloy exhibits higher corrosion resistance and lower passivation current densities than the Ti6Al4V ELI alloy.
