RESUMO
The purpose of this study is the surface modification of Ti10Mo8Nb experimental alloy by using TiO2 nanostructure growth. Ingots of the Ti10Mo8Nb experimental alloy were produced by fusion from sheets of molybdenum, niobium, and titanium commercially pure in an arc melting furnace under argon atmosphere. The potentiostatic anodic oxidation was performed using an electrolyte formed of glycerol and H2O (1: 1 by vol.) with the addition of 2.7% (w/v) NH4F under 20 V for 3 h at room temperature. After the surface treatment, the samples were annealing. The surface of the alloy was analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD), contact angle, surface energy measurements. In vitro studies, such as cell and bacterial adhesion, were performed to evaluate the response of this treatment. The Ti10Mo8Nb alloy exhibited beta phase after the processing. After the surface treatment, a nanoporous layer of TiO was obtained. The anatase phase was found in the annealed samples (450 ºC for 3 hours). In vitro analyzes showed cell growth viability and decreased bacterial proliferation due to the larger specific surface area.
