Wear and biological performances of a thermally oxidized Ti6Al7Nb alloy were investigated. Thermal oxidation (TO) performed at 600 °C for 60 h in air formed a 0.6 μm thick and relatively rough (having an average surface roughness of 1.1 μm) oxide layer (OL) on the surface. The OL was identified as the rutile form of TiO_2 and there was an oxygen diffusion zone (ODZ) with an average thickness of 5 μm just beneath it. The applied TO process resulted in more than ten-fold increase in wear resistance in a simulated body fluid (SBF) solution. Additionally, the biological performance was also enhanced as revealed by SBF immersion and cell culture tests.

Electron beam effect on swelling at the sol-gel derived thin film has been examined for chalcopyrite copper indium gallium diselenium thin-film semiconductor nanolayers with optical pransparent features. The copper indium gallium diselenium layers with the optical transparent features were irradiated by negatively charged electron beam which was emmited from Sr-90 radioisotope with 2.86 mCi activity. The swelling was the important parameters to use this thin film at the optoelectronic layers that have affected the safety and operating life of the equipments and systems in nuclear applications.
