摘要
传统铜基复合材料在提高其强度、硬度、耐磨性等的同时,会大幅降低传导性能和塑韧性,因此很大程度上限制了其应用范围。为了满足高技术领域的需求,改善复合材料的综合性能,利用多元多尺度混杂增强的设计思路,充分发挥各组元的优点和耦合效应,获得了具有高强、高导、高耐磨的铜基复合材料,而且其在高温下依然保持高的强度和优异的抗热疲劳特性。本文综述了混杂增强铜基复合材料增强相的选择、强化机制、制备技术等方面的研究进展,并展望了混杂增强铜基体复合材料的发展方向及需要解决的问题。
Traditional copper matrix composites can greatly reduce the conductivity and ductility while improving the strength,hardness,wear resistance,so their application scope is limited to a great extent. In order to meet the needs of the high-technology field and improve the comprehensive properties of the composite materials,the design idea of multi-scale hybrid reinforcement is used to give full play to the advantages and coupling effects of each component,and the high strength,high conductivity and high wear resistance are obtained.Moreover,high strength and excellent thermal fatigue resistance are maintained at high temperature. In this paper,the research progress in the selection of reinforcement phase,strengthening mechanism and preparation technology of hybrid reinforced copper matrix composites are reviewed. The development direction of hybrid reinforced copper matrix composites and the problems to be solved are also prospected.
