VL - 54 IS - 4 SE - Articles DO - 10.3989/revmetalm.130 UR - https://revistademetalurgia.revistas.csic.es/index.php/revistademetalurgia/article/view/1445 SP - e130 AB - The implant Osseointegration rate depends, among other factors, on the surface´s topography and chemical composition, as in the interactions between the implant surface and cells. In this work the surface free energy for three surface treatments was calculated through contact angle measurements. For the anodic oxidized samples, a heat treatment was carried out to evaluate the influence of this process on the reduction of fluorine content. The aim of this work was study the influence of surface morphology and chemical composition on the alloy´s wettability behavior. The contact angle measurement was analyzed by the sessile drop method. The nanotubes morphology was evaluated by Field Emission Scanning Electron Microscopy (FESEM). The surface composition was analyzed by Energy Dispersive Spectroscopy (EDS). The non-photoinduced nanotubes surface free energy was higher than the polished or acid etched samples. The heat treatment lowered the F/Ti ratio in the nanotube and decreased the contact angle, increasing the interaction with the surface. ER -
