ABSTRACT

Anodizing could be used for bio-functionalization of  the surfaces of  titanium alloys. In this study, we use anodizing for creating nanotubes on the surface of porous titanium alloy bone substitutes manufactured using selective laser melting. Different sets of anodizing parameters (voltage: 10 or 20 V anodizing time: 30 min to 3 h) are used for anodizing porous titanium  structures that were later heat treated at 500o  C. The nanotopographical features are examined  using electron microscopy while the bioactivity of anodized surfaces is measured using  immersion tests in the simulated body fluid (SBF).
