Abstract

Ablation mechanism and properties of SiC_f/SiBCN ceramic composites under an oxyacetylene torch ablation environment were investigated. Ablation products mainly consist of amorphous SiO₂ glass and cristobalite. Four time-dependent ablation actions contribute to the various ablation regions: oxidations of SiC fibers and SiBCN matrix, erosion of SiC fibers in the center region, evaporation of SiO(g) and B₂O₃(g), and high-viscosity SiO₂ liquid flowing with ablation gas-stream. Meanwhile, the mass ablation rate and linear ablation rate of SiC_f/SiBCN are notably lower than those of C_f/SiBCN.
