【摘要】 根据制备过程中金属的状态,从液相法、固相法、金属沉积法三方面介绍了多孔金属材料的制备工艺。液态金属的发泡可以通过直接吹气法发泡法、金属氢化物分解发泡法来实现;固态金属可以通过粉末冶金法、粉末发泡法、金属空心球法和金属粉末纤维烧结法来实现;与前两种不同的是,金属沉积法是采用化学或物理的方法来实现的。最后,讨论了多孔金属材料在结构材料和功能材料两方面的应用。更多还原

【Abstract】 In this paper,preparation and application of the porous metal materials are introduced according to the state of the metal in the process——solid,liquid,gaseous or ionized state. Liquid metal can be formed directly by injecting gas or gas-releasing blowing agent.Solid metal can be formed by various methods,including metal powder slurry foaming,or extrusion and sintering of polymer/powder mixtures. Differently,metal-deposition can be realized by chemic or physical methods. Finally,the structural and functional applications of porous metal materials are presented as well.更多还原
