EIS and LEIS Study on In Vitro Corrosion Resistance of Anodic Oxide Nanotubes on Ti–13Zr–13Nb Alloy in Saline Solution

This work concerns the search for new ways to modify surface of biomedical Ti–13Zr–13Nb alloy applications in regenerative medicine and personalized medicine. Obtained first time, oxide nanotubes (ONTs) layers first-generation (1G) on a were produced by anodizing 0.5% HF electrolyte at 20 V 120 min. The physico-chemical characterization obtained bamboo-inspired 1G ONTs was conducted using TEM ATR-FTIR methods. In vitro corrosion resistance comparative substrate saline solution 37 °C open-circuit potential, Tafel curves, anodic polarization EIS LEIS SVET study local also carried out. It found that modification under proposed conditions allowed obtain porous highly resistant pitting corrosion. results give insight into relationship between morphological parameters macro- microscale.
