POROUS NICKEL FILM FORMING METHOD, RELATING ARTICLE, AND COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a porous nickel film forming method 10.

SOLUTION: The method 10 is a step 12 melting and atomizing two consumable electrode wires containing selected components to form a melted atomized material, and depositing a film on a substrate by forming film deposition on the substrate in a wire electric arc spraying device, and the step comprises a step containing nickel and sacrificial metal as the selected components; and a step decomposing 14 at least a part of the sacrificial metal from the film deposition by applying a positive potential to an alkali electrolyte and obtaining a porous nickel film. An electrolytic cell 40 having an electrode containing the porous nickel film is provided.
