Experimental investigation on C/C material ablation by particle erosion

In purpose of making a study on ablation morphology and performance for C/C material under the direct impact from particles and enriching C/C material ablation study, particle erosion experiment was undertaken. The study has been made for microcosmic ablation morphology by resorting to such measuring approaches as scanning electron microscope, 3D microscopic imaging and etc. The results show that because of direct impact from particle erosion, small dimples are appeared in erosion areas, while with protruded axial rod fibers, on the surfaces of these rods, pits in different sizes are observed with partial monofilaments breaking from matrixes. Therefore, the microcosmic cone-shape holed morphology is formed. It shows that holes and notches are occurred in partial areas of radial fiber bundles, and the whole morphology is no longer in consistency. While the microcosmic morphology for the non-erosion part is in accordance with that morphology at throat with bamboo-shoot monofilaments.
