摘要
泡沫金属具有实体金属不具备的热、声、轻质、能量吸收等优异性能,成为一种新型结构功能材料。被誉为“金属明星”的多孔泡沫铝材料是目前研究最为热门、最具应用潜力的泡沫金属,具有密度小、耐高温、抗腐蚀、不易燃、耐候性好、导热率低、电磁屏蔽强、吸能降噪等优异性能,被广泛应用在汽车工业、航空航天、建筑工业等工程领域。本文综述了泡沫铝材料的结构特征与物理性能,总结了泡沫铝的制备方法、工艺原理及其特点。
The foamed metals have become the new structural functional materials with the excellent properties of heat,sound,light weight,and energy absorption.Known as the“metal star”,the porous aluminum foam is the most popular foam metals with the most potential application,showing the excellent performance as low density,high temperature resistance,good corrosion resistance,non-flammable,good weather resistance,low thermal conductivity,high electromagnetic shielding,high energy absorption,and good noise reduction,which is widely used in the automobile industry,the aeronautics and astronautics industry,and the construction industry.In this paper,the structural characteristics and physical properties of the aluminum foams are reviewed,and the preparation,process principle,and characteristics of the aluminum foams are summarized.
