采用脉冲电镀和多层镀膜技术制备了约8μm厚的PdAg（25．7±0．3）at．％膜，底衬为Φ50的316不锈钢滤片。研究确定了组成单一均匀、结构稳定而且与基体结合牢固的有支撑钯银合金选择渗氢膜的热处理条件。对它的选择渗氢性能进行了考核，350℃时单位面积渗氢速率为商品PdAg25at．％膜的9．1倍。含氦15％的氢经过这种膜纯化后氦含量降为0．03％。研究表明，有支撑钯银合金膜的渗氢性能和纯化效率均能满足我国聚变－裂变混合堆燃料处理的需要。
PdAg (25.7 ± 0.3) at about 8μm thick was prepared by pulse plating and multilayer coating. % Film, the bottom of the Φ50 316 stainless steel filter. The heat treatment conditions of selective hydrogen permeable membrane with palladium-silver alloy supported by a single uniform uniform composition, stable structure and strong bond with the substrate were studied. Hydrogen permeability of its choice of performance assessment, 350 ° C hydrogen permeation rate per unit area of the commodity PdAg25at. 9.1% of the membrane. Hydrogen, which contains 15% of helium, is reduced to 0.03% after purification by this membrane. The results show that both the hydrogen permeation performance and the purification efficiency of supported palladium-silver alloy films can meet the need of fusion-fission hybrid reactor in our country.
