چکیده انگلیسی
In this work we use real-time and in-situ observation technique at high temperature to capture the surface evolution of SiC (silicon carbide) specimen subjected to oxyacetylene torch flame. The obtained real-time images reveal clearly the nucleation, flowing and growth of the liquid silica beads on the surface of the specimen during thermal ablation process. A detailed model is developed to qualitatively analyze and interpret the mechanisms of the nucleation, flowing and the growth of the liquid silica beads. The result is expected to provide a better understanding of the ablation mechanism of SiC materials and serve as a preparatory work for the design and modification of the surface properties and topography of the materials to improve the thermal ablation resistance.
