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

Abstract

Modified titanium nanotubes (TiO2NTs) coatings are grown in simulated body fluid (SBF) from Ticp and Ti6Al4V. 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 TiO2NTs prepared in SBF‐based electrolyte.

TiO2NTs bio-inspired coatings: Revisiting electrochemical, morphological, structural, and mechanical properties

“…A previous study showed that SBF promotes pronounced effects on the increase in mechanical properties and wettability of nanotextured titanium dioxide coatings [27].…”

“…Structural analysis was carried out by x-ray Diffraction (Higaku 600 Benchtop) with Cu Kα=1.5406 Å and radiation at 40 kV and 150 mA. The phase percentage was also extracted, as similarly reported in Simon et al [27].…”

“…Studies published recently [26][27][28], have shown the possibility of modifying the characteristics of TiO 2 NTs coatings by the use of an electrolyte containing simulated body fluid (SBF). The use of this electrolyte during anodization increases the wettability and biocompatibility of the surfaces, while significantly increasing the mechanical adhesion between metal and oxide layers.…”
