高孔隙率多孔金属的制备将配好的金属粉、隔离剂和粘结剂混合后通过挤压或轧制压结成形,清除隔离剂和粘结剂,最后经过烧结可获得预期孔隙率的多孔金属,研究了多孔316L不锈钢和Fe-25Cr-5Al耐热耐蚀合金的制备工艺参数对其性能的影响。指出,隔离剂配合量为90%时,可制得孔隙率高达90%左右的多孔金属。原料中掺加粒
Preparation of high porosity porous metal After mixing with a good metal powder, a release agent and a binder, press forming or rolling is performed to form a separator, the release agent and the binder are removed, and finally the porous material with the desired porosity is obtained by sintering Metal, the effects of preparation parameters of porous 316L stainless steel and Fe-25Cr-5Al heat-resistant corrosion-resistant alloy on its performance were studied. It is pointed out that when the amount of the separating agent is 90%, the porous metal with the porosity up to 90% can be obtained. Raw materials mixed with grain
