In this work, the LENS (Laser Engineered Net Shaping) technique was used to preparation of biomedical Ti6Al7Nb alloy. The surface of Ti-Al-Nb samples obtained by LENS system was modified by electrochemical treatment.The anodization of titanium alloy were performed in glycol-based and glycerol-based 0,3 M NH4F solutions with addition of 2 vol% of water. It was shown that the used electrolytes are able to forming TiO2 with nanoporous/nanotubular morphology on surface of the titanium alloy with Nb content. It was found that growth rate of anodic oxide is faster in glycol-based electrolyte. On the titanium surface after anodization in glycerol-based solution one can see the anodic layer with nanopores, while the collapse TiO2 nanotubes are observed on the Ti surface after glycol-based electrolyte treatment. The current-time curves indicated that oxidation process are faster in glycol-based electrolyte, which is conform by SEM analysis.
