  • Magnetostrictive film, magnetostrictive element, torque sensor, force sensor, pressure sensor, and manufacturing method therefor
    Patent number: 9506824
    Abstract: For providing a magnetostrictive film that can exhibit high magnetostrictive properties in the vicinity of zero magnetic field and their manufacturing methods, a magnetostrictive film thermal sprayed on an object under test includes a metallic glass film subjected to thermal processing at a temperature lower than the glass transition temperature and not lower than the Curie point, and shows a linearity between the magnetic field and the magnetostriction in at least a part of the magnetic field from ?15 kA/m to +15 kA/m (both inclusive).
    Type: Grant
    Filed: July 30, 2010
    Date of Patent: November 29, 2016
    Assignee: JAPAN SCIENCE AND TECHNOLOGY AGENCY

  • Metallic glass laminates, production methods and applications thereof
    Patent number: 7906219
    Abstract: A metallic glass laminate of the present invention is characterized in that a metallic glass layer of amorphous phase is formed on the substrate surface, and there is no continuous pore (pinhole) through the metallic glass layer. The metallic glass laminate is preferably obtained by solidification and lamination of at least part of the metallic glass powder in the molten state or in the supercooled liquid state on the substrate surface. Because of the dense metallic glass layer of homogenous amorphous phase, the functionalities of metallic glass such as corrosion resistance and wear resistance can be satisfactorily provided. A thick and a large-area metallic glass layer can be formed. The metallic glass layer can also be formed into various shapes within the supercooled liquid temperature range. In addition, a metallic glass bulk can be obtained by removing the substrate.
