Abstract

The integrated molding of the coating and modified matrix was achieved by the precursor impregnation and pyrolysis (PIP) method. The average mass ablation rate of the prepared SiCnw-(ZrC-SiC) integrated coating on modified C/C composite material is only 0.60 mg/s after 5 × 120 s of ablation. The coating on the surface of the material is just exfoliated after 3 cycles of ablation. Additionally, there is still a protective layer formed by ZrO₂-SiO₂ on the surface of the matrix after 5 cycles of ablation. The results demonstrate that the integrated coating/matrix-modification is successful in enhancing thermal shock resistance and prolonging ablation life of the material.
