摘要/Abstract

摘要： 为研究粒子直接撞击模式下C/C材料的烧蚀形貌及性能,丰富C/C材料烧蚀研究,开展了粒子侵蚀实验。利用扫描电镜和三维微观成像等测量手段进行微观烧蚀形貌的研究,结果表明颗粒冲刷条件下由于粒子的直接撞击,侵蚀区域出现小凹坑,但轴棒纤维突出,轴棒表面出现大小不同的凹坑,部分单丝从基体中断裂,形成微观锥形孔穴形貌,径向纤维束部分区域出现孔和开槽,整体形貌不再连续一致；未侵蚀部位的微观形貌和烧蚀试验中的喉部形貌一致,单丝呈现笋尖状。 

Abstract: 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.
