以石墨烯和碳纳米管为代表的纳米碳是发展结构功能一体化铝基复合材料的理想增强材料,但纳米碳分散难、与铝润湿差及不良的界面结合等限制了增强效果。针对此问题,介绍了纳米碳/铝复合材料熔融铸造和粉末冶金制备方法的改进及新发展的制备技术,从表面化学改性、涂层及纳米粒子修饰方面总结了纳米碳表面处理与增强铝基复合材料的研究现状。基于纳米碳/铝的界面结合机制,综述了表面改性前后反应和扩散型界面的形成过程及它们与机械锚结型界面对载荷传递的影响、改善途径;分析了纳米碳/铝复合材料研究中涉及的主要增强机制、影响因素和增强效果,并展望了提升该复合材料结构与功能性能的研究重点。
Nanocarbon represented by graphene and carbon nanotube is the ideal reinforcement for developing aluminum matrix composites with integrated structural and functionial properties.However,the high difficulty of nanocarbon dispersity,the poor wetting and bonding of nanocarbon/aluminum interface limit the reinforcing effect.Aiming these issues,the improvements of melt casting and powder metallurgy methods and the new technologies for preparaing nanocarbon/aluminum composites were introduced in this paper.Meanwhile,the research status on the surface treatment of nanocarbon and its reinforced aluminum matrix composites was summarized from the aspects of surface chemistry modification,coating and nanoparticle decoration.Based on the bonding mechanism of nanocarbon/aluminum interface,the formation processes of reaction and diffusion interfaces were reviewed before and after the surface modifications.The contributions of the reaction,diffusion,and mechanically-anchored interfaces on the transfer transfer together with the ways to improve them were also revealed.The influence factors and reinforcing effects of main reinforcing mechanisms involved in the studies of nanocarbon/aluminum composites were analyzed.The investigation focuses on further improving the structural and functional properties of the composites were proposed finally.
