C/C-HfC-SiC composites with simultaneous the resistance to ultra-high temperature airflow erosion and high temperature oxidation
HfC-SiC modified C/C composites containing in situ formed Si-HfC-HfSi2 ablation resistant layer and SiC oxidation resistant layer were successfully prepared by reactive melt infiltration (RMI) combined with gaseous silicon infiltration (GSI). A comparative study was conducted on the anti-oxidation and anti-ablation performance of the C/C-HfC-SiC composites with GSI (noted as RG-CHS) and without GSI (noted as R-CHS). After oxidation at 1,500 °C for 200 min, the oxide film of RG-CHS remained intact. The mass and linear ablation rates decreased from 1.31 mg/s and 7.36 μm/s to 0.12 mg/s and −0.22 μm/s after GSI process, respectively. The introduction of low melting point phases and reducing surface defects can improve the high temperature oxidation resistance and plasma ablation resistance of the composites.
期刊介绍：
The Journal of Materiomics is a peer-reviewed open-access journal that aims to serve as a forum for the continuous dissemination of research within the field of materials science. It particularly emphasizes systematic studies on the relationships between composition, processing, structure, property, and performance of advanced materials. The journal is supported by the Chinese Ceramic Society and is indexed in SCIE and Scopus. It is commonly referred to as J Materiomics.
