Xinfeng maginito kupeza njira zatsopano kusintha maginito coercivity ndi Curie kutentha

Xinfeng maginito opezeka labotale, ndimaginito padziko lapansi osowamaginito aloyi nthawi zambiri amakhudzidwa ndi zinthu zambiri, kwa zaka zambiri akhala akuyesedwa, kufufuza ndi chitukuko cha teknoloji yatsopano kuti apititse patsogoloNdFeb maginito okhazikikakukakamiza mphamvu ndi Curie kutentha, kuti kumapangitsanso bata amphamvu NdFeb osowa dziko maginito pansi Normal Kutentha kapena High Kutentha, ntchito kukweza kwa amphamvu NdFeb maginito makampani ali ndi tanthauzo lalikulu kwambiri.Pali njira ziwiri kuphunzira kusintha kwa coercivity wa osowa dziko okhazikika maginito aloyi: mmodzi ndi kupeza ubale pakati coercivity ndi thupi kapena geometric magawo a aloyi gawo malinga ndi chitsanzo cha thupi ndi mwa njira yoyenera masamu mankhwala.Winayo amatha kuona mwachindunji mgwirizano pakati pa microstructure ya alloy kapena magawo a gawo ndi coercivity kupyolera muzoyesera.

Xinfeng maginito kampani anapeza kuti cobalt, zotayidwa ntchito neodymium chitsulo boroni aloyi, kuwonjezera 10% cobalt, aloyi coercivity pachimake pa 4% zotayidwa;Mukawonjezera 16% cobalt, mphamvu yapamwamba ya aloyi ili pa 2% aluminium.Kuphatikiza kwa aluminiyumu kumawonjezera kukakamiza kwa aloyi ndi cobalt kumawonjezera kutentha kwa Curie kwa alloy.Kuphatikizika kwa ziwirizi, zonse kumapangitsa kuti neodymium iron boron igwire bwino ntchito, ndipo imatha kusintha kutentha kwa Curie kwa Neodymium iron boron.Xinfeng adapezanso kuti ngati muwonjezera kuchuluka kwa niobium, Neodymium iron boronmaginito okhazikikaaloyi akhoza kusintha kutentha Curie nthawi yomweyo, coercivity adzakhala kwambiri bwino.Mouziridwa ndi zotsatira experimental, Xinfeng adzapitiriza kuphunzira kukhazikika maginito osowa dziko okhazikika maginito aloyi, ndi chiyembekezo kuti ntchito ku luso kupanga ndondomeko, chitukuko cha zigawo zikuluzikulu aloyi ndi kupanga posachedwapa, kupititsa patsogolo khalidwe. zogulitsa ndikukulitsa mpikisano wapakatikati wazinthu za Xinfeng.
