Abstract

The ablation resistance of C_f/HfC_PIP-SiC_CVI composites was tested under an oxyacetylene flame. After ablation, many SiO₂ nanowires were in-situ grown in the edge region. From the edge region to the transition region, the melting behaviors of SiO₂ nanowires was gradually intensified, and finally, they completely transformed into SiO₂ glass. At the border of the central region and the transition region, the HfO₂ grains were gradually precipitated from the SiO₂ glass and formed a tubular structure. By comparing the ablation behaviors at different temperatures and times, the ablation mechanisms of C_f/HfC_PIP-SiC_CVI composites was investigated systematically.
