氢气分离用的合金膜包括铂和铜合金的氢气分离膜的制作,其制作方法是用化学喷镀法在耐热多孔介质的表面生成一层铂膜,然后在铂膜上再形成一层铜膜。 合金成分最好是80～92wt％Pt、8～20wt％Cu,其中还含有少量次要成分W、Ni、N_o将上述成分在氩气之类的惰性气氛中熔融、混合成合金,再将合金拉伸制成薄膜,其厚度为60～100μm。多孔耐热介质用多孔的玻璃(A)或(B)制作。玻璃(A)
The alloy membrane for hydrogen separation includes the hydrogen separation membrane of platinum and copper alloy. The production method is that a layer of platinum film is formed on the surface of the heat-resistant porous medium by a chemical spraying method, and then a layer of copper membrane. The alloy composition is preferably 80 to 92 wt% Pt and 8 to 20 wt% Cu, and contains minor amounts of minor components W, Ni and N_o. The above components are melted in an inert atmosphere such as argon and mixed into an alloy, Stretched into a film, the thickness of 60 ~ 100μm. The porous heat-resistant medium is made of porous glass (A) or (B). Glass (A)
