Abstract

The oxidation performance and tribological properties of the anodized Ti45Al8.5Nb were investigated. Anodization was performed in ethylene glycol containing 0.15 mol/L NH4F. Results showed that the anodized Ti45Al8.5Nb alloy exhibited good resistance against oxidation. After 100 h oxidation at 1000 °C, the mass gain of the anodized Ti45Al8.5Nb alloy was only 0.37 mg/cm2. This is attributed to the generation of protective oxide scale. On the other hand, the hardness and elastic modulus of the anodized Ti45Al8.5Nb alloy decreased and then increased with the prolonging of thermal exposure due to the generation of the Al2O3-enriched outermost oxide layer.
