摘要

The ablation behaviour of C/C and C/C-ZrC-SiC composites with cone-shaped holes was studied under an oxyacetylene flame in two heat fluxes. The results showed that C/C-ZrC-SiC composites had a superior ablation resistance in the heat flux of 2.38 MW/m², mainly owing to the ZrO₂-SiO₂ with double structure formed on the surface. As ablated in the heat flux of 4.18 MW/m², the ablation resistance of C/C-ZrC-SiC composites was worse than that of C/C composites since the high temperature corrosion resulted in a heavy evaporation of SiO₂ and the left ZrO₂ skeleton was easily scoured away by the strong scouring force of flame.
