Abstract:
Ti and its alloys with a titanium oxide (TiO2) nanotubes (NTs) surface have received attention in the biomedical field to enhanced biocompatibility by the nanostructured surface. The aim of this study was to investigate the structural and morphological properties of the formation and crystallization of TiO2 NTs on different Ti substrates (c.p-Ti, Ti-15Nb, Ti-40Nb and Ti-35Nb-6Sn alloys). The crystallization of NTs was analyzed by XRD as a function of annealing temperature. The morphology was characterized using FE-SEM equipment and the roughness was evaluated using confocal microscopy. For the c.p-Ti was identified only the presence of rutile oxide and for another ones the mixture of anatase and rutile. The diameter of the NTs was different depends on the substrate and can be represented as: c.p-Ti≈Ti-40Nb >Ti-15Nb≈Ti-34Nb-6Sn. As the same way, the roughness surface increase after annealing treatment and can be represented as: c.p-Ti>Ti-40Nb>Ti-34Nb-6Sn≈Ti-15Nb.
