| 摘 要： | 界面是影响镁基复合材料综合性能的关键因素,如何进行界面调控一直是镁基复合材料的研究热点。本文围绕镁基复合材料三种界面结构类型(共格界面、半共格界面和非共格界面),针对影响界面性能的两个关键问题(界面润湿性和界面反应),综述了界面优化方案的研究进展,提出了实现良好界面结合的界面结构设计与调控准则:良好润湿性与轻微界面反应。针对镁基复合材料的界面性能提升,可以考虑添加稀土元素,起到净化界面、改善润湿性的作用;根据工程需要选择基体和增强体,得到某方面性能优异的复合材料;开发新的增强体表面涂层,充分提高界面结合能力;通过第一性原理等计算模拟方法,深入探究界面结构与界面性能之间的关系。

| Abstract: | Interface is a key factor affecting the comprehensive performance of magnesium matrix composites, and how to carry out interfacial modulation has been a hot research topic in magnesium matrix composites. Focusing on three types of interface structures of magnesium matrix composites (coherent, semi-coherent and incoherent) and two key issues (interfacial wettability and interfacial reaction) affecting the interface properties, the research progress of interface optimization schemes was reviewed in this paper and the guidelines for the design and regulation of interfacial structures to achieve good interfacial bonding were proposed: good wettability and slight interfacial reaction. In view of the improvement of interface properties of magnesium matrix composites, the addition of rare earth elements can be considered in the future to purify the interface and improve wettability. The matrix and reinforcement are selected according to engineering needs to obtain composite materials with excellent performance in certain aspects. New reinforcement surface coatings will be developed to fully enhance the capabilities of interfacial bonding. First-principles and other computational simulation methods will be used to deeply explore the relationship between interface structure and interface performance. |
