Abstract

Carbon fiber-reinforced silicon carbide (C/SiC) and zirconium diboride-zirconium carbide (ZrB₂-ZrC) modified C/SiC (C/SiC-ZrB₂-ZrC) sharp leading edges (SLEs) were prepared in this study. Their ablation behaviors were tested in plasma wind tunnels. The results indicated that the ablation of C/SiC SLEs was controlled by the atomic oxidation of SiC, leading to the elimination of SiC. In contrast, C/SiC-ZrB₂-ZrC SLEs showed little reduction in plasma flows. During ablation, a ZrO₂ skeleton was formed with silica filling inside by the atomic oxidation of SiC. The ZrO₂ skeleton suppressed the consumption of SiC, resulting in the improvement of the ablation resistance of C/SiC-ZrB₂-ZrC SLEs.
