摘要：

The bioactive nanowire of sodium hydrogen titanium oxide (Na0.8H1.2Ti3O7) was obtained by Chemical treating the surface of TiO2-based coating containing Si and Ca (SC) prepared by microarc oxidation (MAO). During the chemical treatment, the dissolution of Ca and Si, and the deposition of Na appear on the surface of the SC coating. The chemically treated SC coating shows better hydrophilic and apatite-formation ability than those of the SC coating, which could be associated with the special structure such as OH group in the sodium hydrogen titanium oxide (SHTO) as well as the Ti-OH group formation during the simulated body fluid immersion. At the same time, the SHTO nanowire is more suitable for the MC3T3-E1 cell adhesion and proliferation due to surface morphology, phase composition, OH group structure and better wetting ability.
