Enhancement of Mechanical Properties and Wettability of TiO₂NT Arrays Formed in Simulated Body Fluid‐Based Electrolyte

Abstract

Modified titanium nanotubes (TiO 2 NTs) coatings are grown in simulated body fluid (SBF) from Ti cp and Ti 6 Al 4 V. The addition of 1% v/v of SBF to the electrolyte neither modifies film morphology nor the structural oxide characteristics for both metal substrates. However, an improvement in mechanical properties (hardness and elasticity model) and wettability is observed. From bioactive assay, a higher amount of fluorapatite was detected on the top of TiO 2 NTs prepared in SBF‐based electrolyte.
