The high-temperature oxidation behavior of TC18 alloy at different temperatures was studied. The results showed that the oxidation behavior followed different kinetics laws at different temperatures, and the resulting oxide films had different phase compositions and morphologies.
The high-temperature air oxidation behaviors at 600 degrees C, 700 degrees C and 800 degrees C of the TC18 alloy were systematically studied. The oxidation kinetics of TC18 alloy, the phase composition, microscopic morphology and chemical composition of the surface oxide films were analyzed to elucidate possible oxidation mechanisms. The results revealed that the oxidation behavior of TC18 alloy followed a linear-parabolic law at 600 degrees C and 700 degrees C while being governed by a simple linear law at 800 degrees C. The long-term oxidation for 24 h at 600 degrees C and 700 degrees C resulted in the oxide films composed of both Ti3O and TiO2, with dominant Ti3O and TiO2 respectively for the oxide films formed at 600 degrees C and 700 degrees C specifically. Especially for the oxidation at 800 degrees C, the oxide film was revealed to consist of three layers of the outer layer Al2O3, the secondary outer layer TiO2 and the dominant inner layer TiO2.
