Enhancing titanium stability in Fusayama saliva using electrochemical elaboration of TiO2 nanotubes

Abstract

Titanium having low density, stability and biocompatibility, is one of the most promising biomaterial of the century even with the natural passive stratum [1,2], but building a nano-tube structure in the last decade using various procedure could lead also to an improvement of a quite large range of properties important in applied chemistry. The aim of the paper is to elaborate electrochemically TiO2 nanotubes and to evaluate the stability increase of Titanium in Fusayama saliva changing the surface morphology from micro TiO2 to TiO2 nanotubes. Anodization at room temperature in a mixture of (NH4)2SO4 and NH4F, was the choice of nanotubes structures elaboration, and cyclic voltammetry was the procedure of stability evaluation. The surface analysis was performed using scanning electron microscopy (SEM), energy-dispersive X-ray microanalysis (EDAX), and atomic force microscopy before and after anodization.
