Manufacturing method of composite material of high permeability amorphous material and Nd-Fe-B permanent magnet using RSP

摘要

The present invention is to produce a high-performance Nd-Fe-B-based permanent magnet material and a high permeability amorphous material as a composite material through the RSP process to complement the brittleness of the Nd-Fe-B-based permanent magnet, a new technology of permanent magnet manufacturing A method of manufacturing a composite material of a high permeability amorphous material and a Nd-Fe-B permanent magnet using RSP to secure It is composed of a heating apparatus for heating by melting and a quenching apparatus for quenching the molten molten metal to prepare in a vacuum or inert gas atmosphere.
