摘要

碳基复合材料，特别是Cf-SiC复合材料在高温下得到了广泛的应用。高超音速飞行器的许多部件都是由这些复合材料制成的。为此，利用感应等离子体腐蚀试验装置，对液态硅浸渍法（LSI）和等温化学蒸汽浸渍法（ICVI）制备的Cf-SiC复合材料进行了高超声速测试。暴露样品的质量损失用半微天平测定。利用扫描电子显微镜对降解表面进行了检测。热解碳/碳化硅[(PyC/SiC) n；采用ICVI技术制备的n = 4]包覆的Cf-SiC复合材料性能最佳。估计材料的主要去除机制是机械侵蚀和烧蚀。

Degradation of Cf-SiC composites under hypersonic conditions

Carbon based composites particularly C_f-SiC composites are finding wide range of applications at elevated temperature. A number of component of hypersonic vehicles are made from these composites. In view of these, C_f-SiC composites fabricated by liquid silicon impregnation (LSI) and isothermal chemical vapor impregnation (ICVI) are exposed to hypersonic condition with the help of an induction plasma based erosion test facility. Mass loss of exposed samples was determined by semi-micro balance. Degraded surfaces were examined with the help of scanning electron microscopy. Pyrocarbon/silicon carbide [(PyC/SiC) n; n = 4] coated C_f-SiC composites fabricated by ICVI technique exhibits the best performance. The main materials removal mechanism is estimated to be mechanical erosion and ablation of investigated material.

期刊介绍： Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
