摘要：

In order to improve the thermal oxidative stability of the neodymium series (Nd2Fe14B) magnetic powder, plasma polymerization of benzene, styrene and acrylonitrile on the powder was carried out and its effect was examined. A strong hydrophobicity was revealed on the surface of the magnetic powder by the plasma treatment, and the thermal oxidative stability and magnetic properties of the powder were remarkably improved. Magnetic properties of the plastic magnets prepared with the magnetic powder coated with plasma polymer of acrylonitrile on the surface, were superior to plastic magnets prepared with untreated powder.
