Microstructure and ablation properties of carbon/carbon composites modified by ZrSiO4
Source abstract
Abstract
Abstract Ablation behavior of C/C–ZrSiO4 composites prepared by a three-step process was studied using oxyacetylene torch. After ablation for 120 s, the linear and mass ablation rates of the composites were 5.91 μm/s and 1.13 mg/s, respectively, which were lower than those of pure C/C composites. The evolution processes of microstructure and composition of the ablation surface with the extension of ablation time were investigated in detail. The heat from the ablation flame was absorbed by the decomposition of ZrSiO4 and the evaporation of SiO2, thereby reducing the high temperature corrosion of the composites.
