在碳/碳（C/C）复合材料表面制备了厚度为80-100 μm的富碳化锆（ZrC）层。富ZrC层由均匀分散在碳基体中的亚微米ZrC颗粒组成。具有富ZrC层的复合材料的质量烧蚀率比裸C/C复合材料的质量烧蚀率低69%。富ZrC层可以封闭表面孔隙和裂纹，抑制缺陷区的择优烧蚀，并形成连续熔化的ZrO 2层，防止烧蚀过程中碳的氧化。富ZrC层的强化可以减少复合材料的机械剥蚀。
Zirconium carbide (ZrC) rich surface layer with a thickness of 80–100 μm was prepared on carbon/carbon (C/C) composites. The ZrC-rich layer consisted of submicron ZrC particles, homogeneously dispersed in the carbon matrix. The mass ablation rate of the composite with the ZrC-rich layer was 69% lower than that of the bare C/C composites. The ZrC-rich layer could seal the surface pores and cracks to restrain the preferential ablation in the defect area and form a continuously melting ZrO2layer to prevent the carbon from oxidizing during ablation. The strengthened ZrC-rich layer could reduce the mechanical denudation of the composites.
