| titleOfInvention | HIGH CORROSION-RESISTANT R-Fe-B-BASE BONDED MAGNET AND METHOD OF MANUFACTURING THE SAME |
| abstract | A method of efficiently manufacturing R-Fe-B-base bondednmagnets of various shapes such as ring shape and disk shape having a highncorrosion resistance and capable of being plated electrically with ease,nwherein the corrosion resistance of the magnet is improved by forming anconductive film of a metal on the surface thereof with tight adhesion,nuniformity and efficiency. The method comprises filling the holes of thenmagnet with polishing powder, inorganic powder and polishing chips, fixingnthese materials in the holes by fat of a vegetable medium and sealing thenresultant holes, and barrel-polishing the magnet by a barrel unit in the drynprocess with indefinitely shaped, i.e. spherical, massive or acicular (wiry)npieces of a required size of Cu, Sn, Zn, Pb, Cd, In, Au, Ag, Fe, Ni, Co, Cr andnAl and such pieces of alloys thereof used as a metallic medium. Said finenpieces of metals such as Cu are press fitted into a resin surface and holes ofnthe bonded magnet and cover the surface and holes and further, cover thensurfaces of particles of magnetic powder whereby a very uniform conductivenfilm can be formed on the surface of the bonded magnet, so that it becomesnpossible to subject the bonded magnet to electric plating excellently andnobtain a plated R-Fe-B-base bonded magnet of a high corrosion resistancenand with minimum deterioration of the magnetic properties. |
