Abstract

The properties of the surface layer on the OT-4-0 titanium alloy after oxygen implantation were examined. Polished samples were implanted with doses of 5 × 1016 and 1 × 1017 O+ cm−2. The O+ ion energy was 50 keV. Transmission electron microscopy has been used to investigate the microstructure of the implanted layers formed on the OT-4-0. It was found that the implanted layers are nanocrystalline rutile (TiO2). Depth profiles of oxygen and titanium were investigated by SIMS and corrosion resistance was analysed by electrochemical techniques. The results indicate that the oxygen implantation increases the corrosion resistance of the OT-4-0 titanium alloy.
