Izinto ezihlala unomphela zikazibuthe wuhlobo olusha lwempahla kazibuthe, eyaziwa nangokuthi yi-hard magnetic material. Futhi i-NdFeb unomphela uzibuthe impahla iyisizukulwane sesithathu sezinto ezingavamile zikazibuthe zomhlaba ezingavamile, ukusetshenziswa kwayo kunganciphisa kakhulu ivolumu nekhwalithi yomshini, njengasesicelo sediski, kungenza i-disk drive miniaturization, futhi ibe nokusebenza okungcono kakhulu. Kumadivayisi alalelwayo, i-NdFeb isetshenziswa kakhulu kuzipikha ezincane, izindlebe nezipikha zezimoto ezisezingeni eliphezulu, ithuthukisa kakhulu ukwethembeka komsindo kanye nesilinganiso sesignali-kuya-nomsindo. Ngaphezu kwalokho, ingasetshenziswa futhi ku-DC motor kanye ne-NUCLEAR imaging resonance magnetic, ikakhulukazi ekusebenziseni isitimela se-magnetic levitation hhayi nje inombolo enkulu, kodwa futhi ingafinyelela ukuhamba ngesivinini esikhulu, ukuphepha, ukwethembeka kanye nezici zomsindo ophansi.
Ukufingqa, i-NdFeb iwubuchwepheshe obusha obuphezulu, futhi indlela yokucubungula uzibuthe ye-NdFeb inendlela ye-sintering nendlela yokubopha, ekuphumeni kohlobo lwe-sintering. Ukukhiqizwa kwe-Sintered NdFeb kusebenzisa inqubo ye-powder metallurgy, indawo engaphezulu ixega futhi i-porous, futhi umngcele wokusanhlamvu ungamandla wesigaba esicebile se-neodymium negative, ngakho ukumelana nokugqwala kubi kakhulu, umazibuthe unomphela ngemuva kokugqwala uzothinta kakhulu izakhiwo zawo kazibuthe kanye nempilo yesevisi. .
Okwamanje, ukusetshenziswa electroplating indlela ukunikeza ungqimba zokuzivikela phezu NdFeb, eliphezulu enamathela kuyisiqinisekiso izinga eliphezulu nokuphila isikhathi eside NdFeb uzibuthe unomphela. Kuyabonakala ukuthi umazibuthe omusha we-NdFeb uhlobene eduze nemboni yokwelapha engaphezulu, futhi njengoba le mboni, i-Xinfeng magnetic material ijabulela idumela eliphezulu embonini.
