| titleOfInvention | Fabrication method of thermoplastic bonded Fe-Cr-Co magnet |
| abstract | In the present invention, iron-chromium-cobalt-based magnetic powder is prepared into crystalline powder using a rapid cooling technique, and then magnetic properties are controlled by an appropriate heat treatment process, and the magnetic powder is pulverized to an appropriate particle size to obtain a plastic resin. The present invention relates to a method for manufacturing a thermoplastic iron-chromium-cobalt-based bonded magnet capable of manufacturing a thermoplastic bonded magnet by injection molding using a binder as a binder.n n n The iron-chromium-cobalt-based alloy is prepared into a microcrystalline quenching powder using a rapid cooling technique, and then pulverized into fine powder, and 0.5 to 4 hours while being loaded with an external magnetic field of 1 to 5 kOe at a temperature range of 600 to 700 ° C. Heat-treating in a magnetic field, aging treatment is carried out while maintaining the temperature at a temperature of 550-620 ° C. for 1 to 10 hours, cooling to 480 ° C. at a rate of 1 to 20 ° C./hr, and obtaining the magnetic powder; And a step of surface-treating using 2.0 wt% silane-based coupling agent, and a step of mixing the surface-treated magnetic powder with 5-15 wt% thermoplastic resin and injection molding the same. ,n n n Inexpensive and simple processes enable the production of thermoplastic iron-chromium-cobalt-based bonded magnets with excellent magnetic properties. |
