摘要：
The corrosion behavior of Ti3SiC2 carbides was studied at 800 and 900 degrees C for 30 and 100 h in a gas mixture containing 0.9448 atm of N-2, 0.031 atm of H2O, and 0.0242 atm of H2S. The scales consisted primarily of rutile TiO2 and amorphous SiO2. Oxidation prevailed, and a small amount of sulfur was present over the whole scale, including the scale/matrix interface. Despite the hostile oxidizing, sulfidizing, and hydriding gas environments, Ti3SiC2 displayed relatively good corrosion resistance due to the formation of SiO2 in addition to TiO2.
