This study presents the test results of Ti-46Al-7Nb-0.7Cr-0.1Si-0.2Ni alloy isothermal oxidation with regard to a coating of SiO2 deposited by the sol-gel method. The oxidation test was carried out in air at 900°C. The SiO2 coating is not an effective and stable diffusive barrier, which would considerably improve oxidation resistance of Ti-46Al-7Nb-0.7Cr-0.1Si-0.2Ni alloy.
