Recent progress on wet-oxygen corrosion resistance of SiCf/SiC composites

Year: 2024

Type: article

Abstract: Being an aero-engine hot-end structural material, silicon carbide fiber (SiC f ) reinforced silicon carbide (SiC) ceramic matrix composites (SiC f /SiC) display remarkable application potential. The wet-oxygen environment inside the aero-engine erodes the composites and leads to their performance degradation, which has become a key factor limiting the long-time service of SiC f /SiC. Finding an appropriate way to improve the wet-oxygen corrosion resistance of the composites is worthy of attention. This paper briefly analyzes the mechanisms of wet-oxygen corrosion and reviews the research progress in modified SiC f /SiC from three aspects: coatings, matrix, and interface. At last, the future development trend of the composites against the wet-oxygen environment is prospected.
