I-Neodymium Magnet, eyaziwa nangokuthi izibuthe zomhlaba eziyivelakancane

Ozibuthe be-Neodymium, ababuye baziwe ngokuthi yizibuthe zomhlaba eziyivelakancane, sebebaluleke kakhulu ezindaweni eziningi zobuchwepheshe besimanje ngenxa yezakhiwo zabo ezingavamile kazibuthe.Lawa zibuthe asetshenziswa kakhulu ezimbonini ezahlukahlukene, okubandakanya i-electronics, imishini yezokwelapha, i-aerospace, namandla avuselelekayo.Muva nje, ithimba lososayensi abavela eNyuvesi yaseTokyo lenze ukutholakala okudabukisayo okungathuthukisa kakhulu ukusebenza kwezibuthe ze-neodymium.

Ocwaningweni olushicilelwe kumagazini i-Nature, abacwaningi babike ukuthi bakhiqize ngempumelelo uzibuthe we-neodymium onokucindezelwa okuphezulu kunanoma yimuphi uzibuthe we-neodymium obikwe ngaphambilini.I-Coercivity isilinganiso sekhono likazibuthe lokumelana ne-demagnetization, futhi ukuphoqa okuphezulu kubalulekile ekusebenzeni okuzinzile kwamadivayisi amaningi, okuhlanganisa amamotho kagesi namajeneretha.

Ukuze kuzuzwe lokhu kuphumelela, ithimba lasebenzisa indlela ebizwa ngokuthi i-spark plasma sintering, ehlanganisa ukushisisa nokupholisa kwengxube yempushana ye-neodymium ne- iron boron.Le nqubo isiza ukuvumelanisa okusanhlamvu kazibuthe kokubalulekile, okubuye kukhulise ukuphoqelela kazibuthe.

Uzibuthe omusha okhiqizwe abacwaningi ube ne-coercivity ye-5.5 tesla, ecishe ibe ngu-20% ephakeme kunomnikazi werekhodi wangaphambilini.Lokhu kuthuthukiswa okuphawulekayo kokuphoqeleka kungase kube nezinhlelo eziningi ezisebenzayo emkhakheni wezinjini zikagesi, ezisetshenziswa ezimbonini eziningi, kuhlanganise nezimoto kanye ne-aerospace.

Abacwaningi baphinde baqaphela ukuthi i-magnet entsha ikhiqizwa ngokusebenzisa inqubo elula futhi ehlanjululwayo, engenza kube lula futhi kungabizi kakhulu ukukhiqiza ama-neodymium magnets asebenza kahle esikhathini esizayo.Lokhu kungaholela ekuthuthukisweni kwamamotho kagesi asebenza kahle kakhulu futhi anokwethenjelwa kanye namajeneretha, okungaba nomthelela omkhulu ezimbonini eziningi futhi okungaba neqhaza ekukhuleni kwemithombo yamandla avuselelekayo.

Sengiphetha, impumelelo yakamuva ocwaningweni lukazibuthe we-neodymium olwenziwa yiNyuvesi yaseTokyo intuthuko ebalulekile engaba nemithelela efinyelela kude ezindaweni eziningi zobuchwepheshe besimanje.Ikhono lokukhiqiza omazibuthe be-neodymium abasebenza kahle kakhulu kusetshenziswa inqubo elula nengahlelekayo lingase liguqule imboni yezimoto zikagesi kanye nejeneretha futhi libe negalelo ekukhuleni kwemithombo yamandla avuselelekayo.
