Abstract

The paper describes the effect of growth TiO₂ nanotubes on titanium surfaces by anodic oxidation forenvironmental and medical applications. The importance of the metallurgical state of TiAl₆V alloy on the growing of TiO₂ nanotubes by anodization will be highlighted. Starting from the possibility of obtaining the TiO₂ nanotubes, the paper presents results on TiO₂ nanotubes grown by electrochemical anodization method, using a solution containing HF 0,4% and having as electrodes, graphiteas cathode and titanium alloy specimens obtained by two technologies: by cold plastic deformation as well as by additive manufacturing process SLS, as anode. So, the nanotubes were produced by anodization and analysed by scanning electron microscopy. The aim of this paper is to compare the electrochemical formation of TiO₂ on the surface of both specimens knowing that the titanium alloys and its oxides are used in many biomedicaland environmental applications, thus providing the importance of nanotubes and the fact that their properties open doors in these fields.
