摘    要:由泡沫铝芯材与金属面板构成的夹心结构具有轻质、高强度、良好的减震性等优点.现存的泡沫铝夹心板的制备方法很多,但均为先制备芯材再进行连接的方法.本研究提出一种新的工艺方法即采用粉末与面板直接轧制然后发泡的方法制备了Fe/Al/Fe泡沫铝夹心结构.研究了泡沫铝芯的发泡不均的问题,分析了发泡前和发泡后面板与泡沫铝芯的冶金结合过程,提出了扩散微观结合机理.最终面板与泡沫芯材通过扩散反应形成了牢固的冶金结合.

关 键 词:夹心结构  粉末轧制  泡沫铝  冶金结合  界面

Abstract:Metal skin-Al-foam core sandwich panels have unique characteristics such as light weight, high stiffness and well damping properties. There are lots of manufacture methods, hut all these methods are to prepare core material first and then join them to skins. Iron/aluminum foam/iron sandwiches were prepared by metal powder and face plate rolling method in this study. Asymmetric foaming problem of aluminum foam core was investigated,metallurgy combination process between face plate and aluminum foam core before and after foaming was analyzed. And diffusion combination mechanism was established. By diffusion reaction a good metallic combination in skin-foam core interface was formed.
Keywords:sandwich structure  powder rolling  foam aluminum  metallurgy bonding  Interface
