Abstract: Recently, it was found that titanium oxide with specific structure of anastase and mile possesses a high bioactive characteristic; this result implies the possibility of preparation of more active titanium by heat treatment in oxygen atmosphere. In this paper, Ti-6Al-7Nb with heal treatment was compared with Ti-6Al-7Nb without heat treatment in order to compare the surface characteristics and the mechanical properties. Data about mechanical behaviour are presented. The mechanical behaviour was determined using optical metallography, Scanning Electron Microscopy, Tensile strength and ultramicrohardness. It resulted that the tested oxide films presented passivation tendency and a very good stability. The pronounced porous oxide layer obtained by heat treatment may be expected to facilitate the incorporation of mineral ions from biological fluids and to improve the bioactive bonding with the living bone.
