摘要
综述了金属泡沫材料的各种制备方法。液相法制备金属泡沫材料包括气体吹入法、固体发泡剂法和固体气体共晶凝固法、熔模铸追法、渗流铸造法、喷射沉积法以及粉末加压熔化法等制备方法。釆用金属粉末烧结法、浆料发泡法等制备工艺可以从固相制备金属泡沫材料。电沉积法以及气相沉积法可用于制备高孔隙率的金属泡沫材料。最后简要总结了金属泡沫材料的应用。
Methods for manufacturing metal foams and other porous metallic structures are reviewed. Liquid metal can he foamed directly by injecting gas or gas-releasing blowing agents,or by solid-gas eutectic solidification. Investment casting, infiltration under pressure or vacuum, spray forming, and melting of powder compacts which contain a blowing agent could also be used for making metal foams. The sintering method,and metal powder slurry foaming can make metal foams even in the solid state. And electro-deposition and metal vapour deposition could also be applied to create highly porous metallic structures. Finally ,various applications of metal foams are discussed.
