A method for fabrication of an hydrogen-permeable membrane, comprising forming an alloy of a target composition and structure from powders by mechanically alloying; and forming a membrane from the alloy of the target composition and structure.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for fabrication of an hydrogen-permeable membrane, comprising: a) forming an alloy of a target composition and structure from powders; and b) forming a membrane from the alloy of the target composition and structure. 2. The method of claim 1 , wherein said step a) comprises mechanically alloying the powders. 3. The method of claim 1 , wherein said step a) comprises mechanically alloying the powders and annealing the alloy. 4. The method of claim 1 , said step a) comprises ball milling the powders. 5. The method of claim 1 , said step a) comprises ball milling the powders and heat treatment. 6. The method of claim 1 , wherein said step b) comprises forming the membrane by cold rolling. 7. The method of claim 1 , wherein said step b) comprises forming the membrane by one of: cold spraying, colloidal spraying and paste painting the alloy of the target composition and structure on a substrate. 8. The method of claim 1 , for fabrication of a Pd alloy hydrogen-permeable membrane, said step a) comprising mechanically alloying at Pd with at least one of Cu, Au and Ag powders. 9. The method of claim 1 , wherein said step a) comprises mechanically alloying Pd, Cu, and Au powders into a fcc PdCuAu alloy and annealing into a bcc PdCuAu alloy. 10. The method of claim 1 , for fabrication of a PdCuAu alloy hydrogen-permeable membrane, said step a) comprising mechanically alloying at least Pd and Cu, and Au powders into a fcc PdCuAu ternary alloy and annealing into a bcc PdCuAu ternary alloy, said step b) comprising cold rolling pellets of the bcc PdCuAu ternary alloy. 11. The method of claim 1 , further comprising at least one of annealing the membrane and polishing the membrane. 12. The method of claim 1 , further comprising cold rolling, annealing and polishing the membrane.
