| Abstract: |
| Objective To investigate the oxidation behaviors of matrix-modified carbon materials with ZrB2-SiC at above 1800 ℃ in 100 kPa air. Method The ablation resistance was tested using the induced heating high-temperature oxidation apparatus, and the microstructure of the oxidation layer and the components of oxides were analyzed by SEM and XRD. Results The oxidation rate of carbon materials was greatly reduced after introducing ZrB2-SiC multiphase. The oxidation dynamic behavior of both the ZrB2-SiC modified carbon material and the pure carbon material followed the linear law. Conclusion The oxidation resistance of matrix-modified carbon materials was significant under ultra-high temperature oxidation conditions. |
