The oxidation behaviors of Ti-10Ta-10Nb alloy and Ti-6Al-4V alloy were studied in dry air atmosphere. Specimens were melted in consumable vacuum arc furnace and homogenized at 1050 ? C for 24 h. Hot rolling was performed at 1000 ? C . Specimens of the alloys were oxidized as the temperature range 400 650 ? C for 30 min. The oxidation behavior of the alloys was analysed by optical microscope, SEM/EDX, XRD, XPS and TGA. Immersion test was performed in 1% Lactic acid. In the microscope observation, oxide layer of Ti-10Ta-10Nb alloy was denser and thinner than Ti-6Al-4V's. The weight gains during the oxidation rapidly increased at the temperature above 600 ? C in Ti-6Al-4V's alloy and 700 ? C in Ti-10Ta-10Nb alloy. According to XRD results, oxide layers were composed of mostly TiO 2 (rutile) phase. It was analysed that the passive film of the Ti alloys consisted of TiO 2 through X-ray photoelectron spectroscopy(XPS) analysis.
