A new compound manufacturing process ofregular Porous metal material based on a closed cubic cell structure

多孔金属材料是一种低密度同时具备诸多优越性能的新型多功能材料。本文主要针对多孔金属材料的制备工艺,介绍了目前国内外研究中常见的一些方法。提出了一种利用金属板材冲压的方式制备基础规则立方体单元,然后通过激光焊接将立方体单元拼接出单层面结构,再将单层结构胶接或是钎焊组合在一起形成所需要的立体多孔金属结构的新型复合制备工艺。最后通过实验验证了该工艺的可行性,并给出了需要改进的地方和未来研究方向。

Porous metal material is a new kind of multifunctional materialwith low density and a lot of superior performances. Aiming at manufacturing process of porous metal materials, this paper introduces some common methods at home and abroad. A kind of regular cellular metal based on cubic structure is proposed, and the cubic cells are manufactured through sheet metal stamping process. Then the cells would be bonded together by laser welding to form one layer. Secondly the respective layers could be bonded together by adhesive or braze-welding to form the block we need. Finally some experiments are carried out to validate the feasibility of this progress, and the improvement and the future work are given.
