Patent number: 6428672Abstract: Disclosed is a technique for manufacturing a Ni—Fe alloy thin foil using a single-step electrodeposition-based plating process without requiring processes such as melting, casting, forging, and rolling. A manufacturing apparatus is provided which includes an electrolyzer adapted to receive an electrolyte containing, as a major component thereof, a solution of nickel and iron compounds, a cathode partially dipped in the electrolyte and arranged in such a fashion that it is rotatable, an anode completely dipped in the electrolyte and arranged in such a fashion that it faces the cathode while being spaced apart from the cathode by a desired distance, and a current supply device adapted to generate a flow of current between the cathode and the anode, whereby a Ni—Fe alloy thin film is electrodeposited to a desired thickness over a surface of the cathode facing the anode, and then peeled off from the surface of the cathode, so that a continuous Ni—Fe alloy thin foil is manufactured.Type: GrantFiled: August 16, 2000Date of Patent: August 6, 2002Assignees: Union Steel Manufacturing Co., Ltd., Korea Institute of Industrial TechnologyInventors: Janghyun Choi, Taihong Yim, Tak Kang, Heungyeol Lee, Joongbae Lee, Sanghyun Jeon, Yongbum Park
