The burn resistant coating with the thickness of 0.2~0.4 mm was prepared on Ti40 titanium substrates by plasma spraying. The microstructure and the cross section morphology of the Ti-based alloys and the burn resistant coating were characterized by OM and SEM. The oxidation resistance properties of substrates and burn resistant coating at 600 °C were studied. Results show that the Ti-based alloys with burn resistant coating were oxidized continuously in 600 °C static air for 100 h, and afterwards that the mass gain is decreased by 76% and the oxidation rate is decreased by 92% with contrast to the no-coating Ti-based alloys. It is shown that the oxidation resistance is improved by 12 times. In addition, the burn resistant coating is fully perfect after oxidation test, so it is concluded that the burn resistant coating can provide excellent oxidation resistance and be applied to the titanium fire resistance for titanium alloy parts in aero-engine
