Uburyo magnesi ya neodymium ikorwa

Tuzasobanura uburyoNdFeBByakozwe hamwe nibisobanuro byoroshye.Imashini ya neodymium ni rukuruzi ihoraho ikozwe mu ruvange rwa neodymium, fer, na boron kugirango ibe Nd2Fe14B tetragonal kristaline.Imashini ya neodymium ya sinte ikozwe na vacuum ishyushya ibyuma bidasanzwe byisi nkibikoresho fatizo mu itanura.Nyuma yo kubona ibikoresho bibisi, tuzakora intambwe 9 zo gukora magnet ya NdFeB hanyuma amaherezo tubyare umusaruro urangiye.

Tegura ibikoresho byo kubyitwaramo, gushonga, gusya, gukanda, gucumura, gutunganya, gusya, gukanda no kugenzura.

Tegura ibikoresho byo kubyitwaramo

Imiterere ya chimique ya neodymium magnet ni Nd2Fe14B.

Ubusanzwe Magneti ikungahaye kuri Nd na B, kandi magneti yarangije ubusanzwe arimo ibibanza bidafite imbaraga za Nd na B mubinyampeke, birimo magnetiki Nd2Fe14B.ibinyampeke.Ibindi bintu byinshi bidasanzwe byisi birashobora kongerwaho kugirango bisimbuze igice cya neodymium: dysprosium, terbium, gadolinium, holmium, lanthanum, na cerium.Umuringa, cobalt, aluminium, gallium na niobium urashobora kongerwamo kugirango utezimbere indi miterere ya rukuruzi.Birasanzwe gukoresha Co na Dy hamwe.Ibintu byose byo gukora magnesi yo murwego rwatoranijwe bishyirwa mu itanura rya vacuum induction, gushyuha no gushonga kugirango bibe ibikoresho bivanze.

Gushonga

Ibikoresho fatizo bigomba gushongeshwa mu itanura rya vacuum kugirango bibe umusemburo wa Nd2Fe14B.Ibicuruzwa birashyuha mugukora umuyaga, byose biri mu cyuho kugirango wirinde kwanduza kwinjira.Igicuruzwa cyanyuma cyiyi ntambwe ni urupapuro ruto cyane (urupapuro rwa SC) rugizwe na kristu imwe ya Nd2Fe14B.Uburyo bwo gushonga bugomba gukorwa mugihe gito cyane kugirango wirinde okiside ikabije yubutaka budasanzwe.

Gusya

Intambwe 2 yo gusya ikoreshwa mubikorwa byo gukora.Intambwe yambere, yitwa hydrogen detonation, ikubiyemo reaction hagati ya hydrogène na neodymium hamwe nuruvange, kumena ibice bya SC mo uduce duto.Intambwe ya kabiri, yiswe urusyo, ihindura ibice bya Nd2Fe14B mo ibice bito, bingana na diameter kuva 2-5 mm.Gusya indege bigabanya ibikoresho bivamo ifu yubunini buke cyane.Impuzandengo y'ibice bingana ni microne 3.

Kanda

Ifu ya NdFeB ikanda muburyo bukomeye muburyo bwifuzwa mumashanyarazi akomeye.Gucomeka gukomeye bizabona kandi bikomeze icyerekezo cya magnetisiyoneri.Mu buhanga bwitwa gupfa-kubabaza, ifu ikanda mubikomeye bipfa nka 725 ° C.Igikomeye noneho gishyirwa muburyo bwa kabiri, aho gihunitswe muburyo bwagutse, hafi kimwe cya kabiri cyuburebure bwumwimerere.Ibi bituma icyerekezo cya magnetisiyonike cyerekanwe nicyerekezo cyo gukuramo.Kubishusho bimwe, hariho uburyo burimo clamp zitanga umurongo wa magneti mugihe cyo gukanda kugirango uhuze ibice.

Gucumura

Kanda kuri NdFeB ibikenewe bigomba gucumurwa kugirango bibe NdFeB.Ibikoresho bigabanijwe ku bushyuhe bwo hejuru (kugeza kuri 1080 ° C) munsi yo gushonga kwibintu kugeza igihe ibice byayo bifatanye.Inzira yo gucumura igizwe nintambwe 3: dehydrogenation, gucumura no gutuza.

Imashini

Imashini zicapuwe zaciwe muburyo bwifuzwa nubunini ukoresheje uburyo bwo gusya.Ntibisanzwe, imiterere igoye yitwa imiterere idasanzwe ikorwa no gutunganya amashanyarazi (EDM).Bitewe nigiciro kinini cyibikoresho, igihombo cyibikoresho kubera gutunganya gikomeza kuba gito.Huizhou Fullzen Technology ninziza cyane mugukora magnesi zidasanzwe.

Gufata / Gupfundikanya

NdFeB idapfundikijwe iragoramye cyane kandi itakaza magnetisme vuba iyo itose.Noneho, magnetique yose iboneka mubucuruzi bisaba gutwikira.Magneti kugiti cye ashyizwe mubice bitatu: nikel, umuringa na nikel.Kubwoko bwinshi bwo gutwikira, nyamuneka kanda "Twandikire".

Gukoresha rukuruzi

Magneti ashyirwa mubintu byerekana magneti mumashanyarazi akomeye cyane mugihe gito.Nubusanzwe igiceri kinini kizengurutse rukuruzi.Ibikoresho bya magneti bikoresha amabanki ya capacitor hamwe na voltage ndende cyane kugirango ubone imbaraga zikomeye mugihe gito.

Kugenzura

Reba ubuziranenge bwa magnesi zavuyemo kubiranga bitandukanye.Porogaramu yo gupima imibare igenzura ibipimo.Sisitemu yo gupima umubyimba ukoresheje tekinoroji ya X-ray fluorescence igenzura ubugari bwimyenda.Kwipimisha buri gihe muri spray yumunyu no gupima igitutu nabyo bigenzura imikorere ya coating.Ikarita ya hystereze ipima umurongo wa BH umurongo wa magneti, ukemeza ko wuzuye, nkuko byateganijwe kurwego rwa magneti.

Amaherezo twabonye ibicuruzwa byiza bya magneti.
