摘要
由仿生贝壳独特的“砖+泥”结构制备的金属陶瓷层状复合材料已被证明具有良好的强度和韧性,逐渐成为国内外学者的研究重点。本文综述Al基、Ti基、Ni基及其他常见金属陶瓷层状复合材料的研究现状,并着重介绍了制备方法、工艺特点和工艺流程;归纳总结金属陶瓷层状复合材料常见的裂纹偏转、多重裂纹扩展和裂纹桥接等形式失效破坏模式,控制界面反应和改善界面润湿性可提高金属陶瓷层状复合材料的界面结合强度。优化制备工艺和掌握破坏机理是实现金属陶瓷层状复合材料工程化应用的基础,将计算科学引入对金属/陶瓷界面和损伤机制的研究是实现整个制备过程可操控性的有效途径,实现产品的大尺寸化和形状多样化是其大规模应用化推广的关键。
The metal/ceramic laminated composites prepared from the unique“brick+mud”structure of biomimetic shells have been proved to have better strength and toughness,and have gradually become the research focus at domestic and abroad.In this paper,the current research of Al-based,Ti-based,Ni-based and other common metal/ceramic laminated composites is introduced,and the characteristic and process of each method are analyzed.The failure modes such as crack deflection,multiple crack propagation and crack bridging in metal/ceramic laminated composites are commonly summarized.The interface bonding strength of metal/ceramic laminated composites can be increased by controlling interfacial reactions and improving interfacial wettability.Optimizing of the preparation process and understanding the failure mechanism are the basis of engineering application of metalceramic layered composite materials.The introduction of the computational science into the research of metal/ceramic interface and damage mechanisms is an effective way to realize the controllability of the whole preparation process,and the realization of large size and diversified shape of products is the key to its large-scale application and promotion.
