    摘要:

    纤维增强SiC陶瓷基复合材料具有密度低、强度高、耐高温、抗氧化、耐腐蚀等优点,在航空航天及其他高温条件使用领域具有广泛的应用潜力。然而难加工特点制约了这类材料的广泛使用。由于存在硬度高、脆性大和各向异性特点,高精度低损伤加工成为其工程应用必须解决的关键技术之一。本文主要综述了近年来纤维增强SiC陶瓷基复合材料加工技术研究进展,综合分析了不同加工方法的加工原理、理论模型构建、工艺参数优化、表面质量控制与损伤形成机制等,讨论了当前存在的主要问题,对未来研究方向提出了发展与展望。

    Abstract:

    Fiber reinforced SiC matrix composites (FRCMC-SiC) have significant potential in aerospace application and other high temperature conditions due to their special properties such as low density, high strength, thermostability, anti-oxidation and anti-ablation. However, the application of these composites has been hindered seriously because of their poor machining characteristics. The high-quality and low-damage machining technology must be solved in the use of this kind of high hardness, high brittleness and anisotropy materials. In this paper, the recent progress on the different machining technologies of FRCMC-SiC is reviewed. The material removal mechanism, theoretical model construction, parameters optimization, defect form and surface quality control are summarized and discussed. Finally, the existing problems are discussed, and the development trend of machining technology of FRCMC-SiC in the future is also put forward.
