In recent years, hypersonic aircraft has attracted more and more attention and developed for military power all over the world due to its great military and economic value. It’s components in hot end put forward higher requirements for the materials, in order to adapt to this kind of environment, so ultra- high temperature ceramics materials become the focus of research development. The carbide and boride of Zr, the carbide and boride of Hf are the preferred materials for ultra high temperature conditions, because of the excellent high temperature performance. So the oxidation and ablation resistance properties in high temperature condition become the key indicator for these materials. In this paper, the samples of ZrC-SiC 、ZrB2-SiC、HfC-SiC、HfB2-SiC were ablated by the supersonic speed gas flow. The result is get the content of SiC and ablation temperature on the impact of rhe oxidation and ablation resistance performance and the ablative layer structure.As can be seen, ZrC-SiC、Zr B2-SiC、HfC-SiC、HfB2-SiC have good oxidation and ablation resistance.
