A new Ti-10Ta-10Nb alloy has designed and examined some possibility of forming more passiveoxide film by oxidation treatment which is closely related to corrosion resistance andbiocompatibility. Ti-6Al-4V and Ti-10Ta-10Nb alloys were prepared by consumable vacuum arcmelting and homogenized at 1050for 24hours. Alloy specimens were oxidized at thetemperature range of 400 to 750for 30minutes, and the oxide films on Ti alloys were analysedby optical microscope, SEM, XPS and TGA. Cytotoxicity test was performed in MTT assay treatedL929 fibroblast cell culture by indirect method.It is found out that the oxide film on Ti-10Ta-10Nb alloy is denser and thinner compared to Ti-6Al-4V alloy. The weight gain during the oxidation was increased rapidly at the temperature above650for Ti-6Al-4V alloy and above 700for Ti-10Ta-10Nb alloy respectively. It was analysedthat the passive film of the Ti alloys consisted of TiO2 through X-ray photoelectron spectroscopy(XPS) analysis. It is found out by cytotoxicity test that moderate oxidation treatment lowers celltoxicity, and Ti-10Ta-10Nb alloy showed better result compared to Ti-6Al-4V alloy.
