Abstract

The oxidation behavior and corrosion mechanism of SiC ceramics were investigated at high temperatures ranging from 1000 ℃ to 1200 ℃ in wet environments (75 % water/25 % air). The results demonstrate the formation of protective SiO₂ layers, which effectively inhibit further oxidation at 1000 ℃ and 1100 ℃. However, simultaneous oxidation and water vapor corrosion occur at 1200 ℃, leading to substantial weight loss and the development of numerous porous layers that can reach up to 30 μm after 10 h oxidation. The YAG phases in the SiC ceramics react with SiO₂ to generate Y₂Si₂O₇, Y₂SiO₅, and/or Al₂Si₂O₇ phases during oxidation process, which exhibit enhanced corrosion resistance under wet environments.
