High-Temperature Oxidation of Ti3SiC2-Based Materials Prepared by Spark Plasma Sintering

Resumo

Materials based on the titanium carbosilicide Ti₃SiC₂ (MAX phase), prepared by spark plasma sintering (SPS), have been subjected to high-temperature tests. The high-temperature behavior of samples containing the carbosilicide phase and carbosilicide-free samples were studied. The results demonstrate that the presence of the MAX phase improves the heat resistance of the material, preventing oxidation. The oxidation products of the titanium carbosilicide-based materials are titanium dioxide, silicon monoxide, and carbon dioxide.
