✧ Uhlolojikelele
Ozibuthe be-NIB bafika ngamamaki ahlukene, ahambisana namandla ezinkambu kazibuthe, kusukela ku-N35 (ebuthaka kakhulu futhi engabizi kakhulu) kuya ku-N52 (eqine kakhulu, ebiza kakhulu futhi eshwabene kakhulu). Uzibuthe we-N52 cishe unamandla angama-50% kunozibuthe we-N35 (52/35 = 1.49). E-US, kujwayelekile ukuthola omazibuthe bebanga labathengi ebangeni le-N40 kuye ku-N42. Ekukhiqizeni ivolumu, i-N35 ivame ukusetshenziswa uma usayizi nesisindo kungekona ukucatshangelwa okukhulu njengoba kubiza kancane. Uma usayizi nesisindo kuyizici ezibalulekile, amamaki aphezulu asetshenziswa ngokujwayelekile. Kunemali ekhokhwayo enanini likamazibuthe webanga eliphakeme kakhulu ngakho kuvame kakhulu ukubona omagnethi be-N48 kanye no-N50 besetshenziswa ekukhiqizeni uma kuqhathaniswa no-N52.

Ozibuthe be-Neodymium noma abaziwa kakhulu ngokuthi yi-NIB, i-NefeB noma omagnethi abakhulu banamandla futhi basetshenziswa kakhulu omazibuthe bezentengiselwano abatholakala emhlabeni wonke. Ngokwakheka kwamakhemikhali kwe-Nd2Fe14B, omagnethi be-neo banesakhiwo se-tetragonal crystalline futhi ikakhulukazi bakhiwa izici ze-neodymium, Iron ne-Boron. Ngokuhamba kweminyaka, uzibuthe we-neodymium uphumelele esikhundleni sazo zonke ezinye izinhlobo zozibuthe ezihlala njalo ukuze zisetshenziswe kabanzi kumamotho, izinto zikagesi kanye nezinye izinsimbi ezahlukahlukene zokuphila. Ngenxa yomehluko esidingweni sikazibuthe namandla okudonsa ngomsebenzi ngamunye, ozibuthe be-neodymium batholakala kalula emabangeni ahlukene. Ozibuthe be-NIB bahlelwa ngokuya ngezinto abakhiwe ngazo. Njengomthetho oyisisekelo, ukuphakamisa amamaki, i-magnet izoba namandla.
I-nomenclature ye-neodymium ihlale iqala ngo-'N' elandelwa izinombolo zamadijithi amabili phakathi kochungechunge lwama-24 kuya ku-52. Uhlamvu 'N' emabangeni ezibuthe ze-neo lumelela i-neodymium kuyilapho izinombolo ezilandelayo zimelela umkhiqizo wamandla omkhulu womkhiqizo othize. uzibuthe okalwa nge-'Mega Gauss Oersteds (MGOe). I-Mgoe iyinkomba eyisisekelo yamandla anoma yimuphi uzibuthe we-neo kanye nobubanzi bezibuthe ezikhiqizwe yiyo ngaphakathi kwanoma iyiphi into noma uhlelo lokusebenza. Nakuba uhla lwangempela luqala ngo-N24 nokho, amabanga aphansi awasakhiqizwa. Ngokufanayo, nakuba amandla amaningi omkhiqizo angaba khona we-NIB alinganiselwa ukuthi azofinyelela ku-N64 nokho amazinga anjalo aphezulu amandla awakahlolisiswa ngokwezentengiso futhi i-N52 iyizinga eliphezulu kakhulu lamanje le-neo elenziwe litholakale kalula kubathengi.
Noma yiziphi izinhlamvu ezengeziwe ezilandela ibanga zibhekisela ezilinganisweni zokushisa zikazibuthe, noma mhlawumbe ukungabikho kwawo. Izilinganiso zokushisa ezijwayelekile zithi Nil-MH-SH-UH-EH. Lezi zinhlamvu zokugcina zimelela izinga lokushisa eliphezulu elisebenzayo eliwumkhawulo okungukuthi izinga lokushisa lika-Curie uzibuthe elingamelana nalo ngaphambi kokuba lilahlekelwe unomphela uzibuthe. Uma uzibuthe usebenza ngaphezu kwezinga lokushisa le-Curie, umphumela kungaba ukulahlekelwa okukhiphayo, ukuncipha kokukhiqiza futhi ekugcineni ukuphelelwa amandla kazibuthe okungenakuguqulwa.
Kodwa-ke, ubukhulu bomzimba kanye nokuma kwanoma yimuphi uzibuthe we-neodymium nakho kudlala indima ebalulekile ekhonweni layo lokusebenza ngempumelelo emazingeni okushisa aphakeme ngokuqhathaniswa. Ngaphezu kwalokho, enye into okufanele uyikhumbule ukuthi amandla kazibuthe wekhwalithi enhle alingana nenombolo, ukuze i-N37 ibe buthakathaka ngo-9% kune-N46. Indlela enokwethenjelwa kakhulu yokubala ibanga eliqondile likazibuthe we-neo ngokusebenzisa umshini wokuhlola igrafu we-hysteresis.
I-AH Magnet ingumphakeli wezibuthe womhlaba oyivelakancane okhethekile ekucwaningeni, ekuthuthukiseni, ekukhiqizeni nasekuthumeleni kwamanye amazwe omazibuthe bensimbi be-sintered be-neodymium bensimbi, amamaki angama-47 wezibuthe ezijwayelekile ze-neodymium, ukusuka ku-N33 kuye ku-35AH, kanye nochungechunge lwe-GBD olusuka ku-48SH kuya ku-45AH luyatholakala. Uma unentshisekelo ngemikhiqizo yethu, sicela usithinte manje!
