| 摘 要： | 采用等离子烧蚀装置对ZrCP/W复合材料的烧蚀性能进行了研究.结果表明:ZrCP/W复合材料的线烧蚀率随ZrC含量和烧蚀时间的增加而增大.烧蚀后,在试样表面形成了烧蚀坑和熔融层,熔融层的厚度达到1 mm左右.在烧蚀过程中,烧蚀层中的物相发生了化学反应,并生成了新相.复合材料的主要烧蚀机制是以熔化烧蚀为主,兼有热化学烧蚀.

| Abstract: | The ablation behaviors of ZrCp/W composites were measured using a plasma ablation equipment. The results indicate that the linear ablation rate increases with increasing of ZrC content and ablation time. The ablation delve and the melted layer with a thickness of 1 mm appeared in the ablated surface. The chemical reaction between the constituted phases was happened in the ablation process, and the new phases were formed. The main ablation mechanism of the composites is the melting ablation which dominated a... |
