    Project Details


    The general purpose of the project is to raise the national level of understanding and knowledge of magnetic materials.
    1. Permanent Magnets based on rare-earths.
    1a. Production of polymer-bonded isotropic magnets.
    1b. Measure the long-term stability of such magnets at 100 deg.C, aiming at a life-time of 10 years.
    1c. Characterization of the magnetic, physical, and corrosion properties of such magnets.
    1d. Production of surface layers of permanent magnet material on a steel matrix.
    2. Soft iron-based magnets.
    2a. To produce magnets by the powder metallurgy route with a low hysteresis loss and with the potential of application at higher frequencies. A Chinese research fellow, Mr. Gang Wu, investigated the properties of ferritic stainless steels produced by powder metallurgy.
    2b. To produce polymer-bonded magnets to be applied at higher frequencies with a low eddy-current loss.
    2c. Characterization of the magnetic, physical, tribological, and corrosion properties of soft magnets.
    3. End-use of magnet materials.
    3a. Modelling of constructions (motors and transducers) on basis of the properties measured.
    3b. Manufacturing of such constructions.
