Microstructural influence on corrosion behavior and the TiO2 nanostructured layer growth in the Ti–10Mo–3Sn alloy
β-metastable titanium alloys have received special attention in prosthesis manufacturing due to their good mechanical behavior and superior biocompatibility. Nonetheless, the addition of self-organized titanium (IV) oxide (TiO2) on the component surface has been needed to improve its bioactivity and osseointegration. In this investigation, the effect of the substrate microstructure on corrosion behavior and TiO2 nanotube formation was studied in the β-metastable Ti–10Mo–3Sn (% wt.) alloy. Self-organized TiO2 was prepared by anodization of Ti–10Mo–3Sn (% wt.) alloy after solution heat treatment at 1000 °C and aging treatments at 500 °C and 600 °C. Changes in surface nanotopography were verified as a function of the substrate microstructure and the electrolyte composition. The presence of finer precipitation leads to a thicker layer of TiO2 nanotubes and an increase in their diameters was observed at higher aging temperatures.
