Imashini za SmCo, Samarium Cobalt (Sm-Co), Isi idasanzwe SmCo Imashini zihoraho
Magneti ya samarium-cobalt (SmCo) ni ubwoko bwa rukuruzi idasanzwe-yisi igizwe nibintu bibiri by'ibanze: samariyumu na cobalt.SmCo Magnets ni isi idasanzwe ya magneti yigihe cya kabiri.Magari ya Samarium-cobalt irapimwe ugereranijeneodymiummubijyanye nimbaraga ariko zifite igipimo kinini cyubushyuhe hamwe nigitugu.Honsen Magnetics itanga SmCo5 na Sm2Co17 magnet muburyo butandukanye.
Sm-Co niyo ihitamo kubisabwa na moteri isabwa cyane kubera ko irwanya imbaraga za demagnetizing hamwe nubushyuhe budasanzwe bwumuriro.Byongeye kandi, kurwanya ruswa ni byiza cyane kuruta Nd-Fe-B.Magnet igomba gukomeza gutwikirwa mubihe bya acide.Kurwanya ruswa byanatanze icyizere kubantu batekereza gukoresha magnesi mubikorwa byubuvuzi.

Urukurikirane
Magari ya Samarium - cobalt iraboneka muri "serie" ebyiri, arizo SmCo5rukuruzi na Sm2Co17rukuruzi.SmCo5 ifite ibicuruzwa bitanga ingufu zingana na 15-22 MGOe, naho urukurikirane rwa kabiri rwa magneti ya Samarium Cobalt, Sm2Co17, rufite intera iri hagati ya 22 na 30 MGOe.
Ibiranga
Demagnetisation iragoye cyane kuri samarium-cobalt
Imashini ya SmCo ni ubushyuhe buhamye.
Birahenze kandi biterwa nihindagurika ryibiciro (cobalt irumva ibiciro byisoko).
Imashini ya Samarium-cobalt ifite ruswa nyinshi kandi irwanya okiside, ntibikunze gutwikirwa kandi birashobora gukoreshwa
Magneti ya Samarium-cobalt iroroshye kandi iracika kandi byoroshye.
Imashini ya Samarium-cobalt yacumuye yerekana magnetiki anisotropy, igabanya icyerekezo cya magnetisiyasi kugera kumurongo wicyerekezo cya magneti.Ibi bigerwaho muguhuza ibikoresho bya kristu yibikoresho nkuko biri gukorwa.
Umusaruro wo gutunganya Samarium Cobalt Imashini zihoraho
Inzira y'ifu → Kanda → Gucumura test Ikizamini cya magnetiki → gukata → ibicuruzwa byarangiye
Ibikoresho bya Samarium cobalt bikunze gutunganywa mugihe kitarimo magneti, hamwe nuruziga rwa diyama hamwe no gusya neza, bikaba bikenewe.Kubera ubushyuhe buke, samarium cobalt ntigomba gukama rwose.Umucyo muto cyangwa amashanyarazi ahamye mubikorwa birashobora gukurura umuriro byoroshye, hamwe nubushyuhe bwo hejuru cyane, bigoye kubigenzura.
Imashini ya SmCo VS Yacumuye NdFeB
Ibikurikira nibitandukaniro nyamukuru hagati ya magnet ya NdFeB yacumuye na MagnC ya SmCo:
1. Imbaraga za rukuruzi
Imbaraga za rukuruzi za magneti ya neodymium ihoraho iruta iya magnet ya SmCo.Icapa NdFeB ifite (BH) Max igera kuri 53MGOe, mugihe ibikoresho bya SmCo bifite Max (BH) Max ya 32MGOe.Ugereranije nibikoresho bya NdFeb, ibikoresho bya SmCo nibyiza mukurwanya demagnetisation.
2. Kurwanya ubushyuhe bwo hejuru
Kubijyanye nubushyuhe bwo hejuru, NdFeB ntabwo iruta SmCo.NdFeB irashobora kwihanganira ubushyuhe bugera kuri 200 ° C mugihe SmCo ishobora kwihanganira ubushyuhe bugera kuri 350 ° C.
3. Kurwanya ruswa
Magnet ya NdFeB irwana no kurwanya ruswa na okiside.Mubisanzwe, bakeneye gushyirwaho isahani cyangwa no gupakira vacuum kugirango babirinde.Zinc, nikel, epoxy, nibindi bikoresho byo gutwikira bikoreshwa kenshi.Magnets ikozwe muri SmCo ntishobora kubora
4. Shiraho, gutunganya no guterana
Bitewe no gucika intege kwabo, NdFeb na SmCo ntibishobora kubyazwa umusaruro hakoreshejwe uburyo busanzwe bwo gutema.Umuziga wa diyama hamwe no gukata insinga za electrode nuburyo bubiri bwingenzi bwo gutunganya.Ibi bigabanya imiterere ya magnesi zishobora gukorwa.Imiterere irakomeye ntishobora gukoreshwa.Ibikoresho bya SmCo biroroshye kandi bimeneka ugereranije nibindi bikoresho.Kubwibyo, mugihe wubaka no gukoresha magneti ya SmCo, nyamuneka witonde cyane.
5. Igiciro
Imashini za SmCo zari zihenze inshuro ebyiri, niba zitari zihenze inshuro eshatu, nka magneti ya NdFeB mu myaka mike ishize.Bitewe na politiki ibuza igihugu mu bucukuzi bw'ubutaka budasanzwe, igiciro cya NdFeB cyazamutse cyane mu myaka yashize.Mubusanzwe, magnet ya NdFeB isanzwe ihenze kuruta samarium cobalt.
Porogaramu
Kurwanya cyane ruswa na okiside, MagnC zihoraho za SmCo zisanga zikoreshwa cyane mubijyanye nindege, ikirere, ikirere cyigihugu, ingabo, ndetse no mubikorwa bya microwave, ibikoresho byo kuvura, ibikoresho, nibikoresho, ndetse nibindi bitandukanye ubwoko bwa magnetiki sensor, gutunganya, moteri, hamwe na magneti yo guterura.Inganda nkizo zikoreshwa muri NdFeB zirimo guhinduranya, indangururamajwi, moteri yamashanyarazi, ibikoresho, na sensor.
SmCo5 biroroshye guhinduranya mumashanyarazi yihariye kuruta magnet ya SmCo 2:17.
In Sm2Co17rukuruzi, uburyo bwo guhatira gushingira kumurongo wurukuta.
