碳化硅陶瓷基复合材料(CMC-Si C)是一种新型战略性热结构材料,在航空、航天、核能等高新技术领域具有广阔应用前景。但CMC-Si C材料硬度高、不导电等特性决定了实现其高精度、高质量加工较为困难。综述了CMC-Si C材料的传统加工和特种加工工艺的研究现状与进展,重点阐述了激光加工陶瓷及CMC-Si C材料的加工机理和加工效果。最后,指出了CMC-Si C材料加工技术的发展趋势。
Silicon Carbide Ceramic Matrix Composites (CMC-Si C) is a new type of strategic thermal structure material with broad application prospects in high-tech fields such as aviation, aerospace and nuclear energy. However, CMC-Si C materials, high hardness, non-conductive properties determine the realization of its high-precision, high-quality processing more difficult. The research status and progress of traditional processing and special processing technology of CMC-Si C material are reviewed. The machining mechanism and processing effect of laser processing ceramic and CMC-Si C material are emphatically described. Finally, the development trend of CMC-Si C material processing technology is pointed out.
