I-Samarium Cobalt (SmCo) Magnets
Ama-Samarium Cobalt Magnets (SmCo Magnets) awuhlobo lwezinto ezisebenza kahle zikazibuthe ezisebenza unomphela. Akhiqizwa kusetshenziswa i-metallic samarium, i-cobalt, nezinye izinsimbi ezingavamile, okuzenza zibe yimali kazibuthe ebiza kakhulu ukukhiqiza. Inqubo yokukhiqiza ibandakanya ukuncibilika, ukugaywa, ukucindezela, nokucwilisa, okuholela ezimpahleni ezihlukene kanye namabanga omazibuthe. Enye inzuzo ephawulekayo kamazibuthe be-SmCo ukumelana kwabo okuphezulu nokugqwala, kanye nekhono labo lokumelana nezinga lokushisa eliphezulu, lifinyelela ku-350 °C, futhi ngezinye izikhathi ngisho no-500 °C. Lokhu ukumelana nezinga lokushisa kubenza bahluke kwabanye odonsa unomphela abanokubekezelela okuphansi emazingeni okushisa okwedlulele, okunikeza ozibuthe be-SmCo unqenqema olubalulekile.
Njengokucaciswa kwekhasimende, ama-roughcasts we-SmCo Magnets azocutshungulwa ngomshini ukuze athole ukwakheka nosayizi oyifunayo. Ngaphandle uma kuyalwe ngenye indlela ikhasimende, imikhiqizo yokugcina izokwenziwa uzibuthe. Izinto zikazibuthe, ezinjengama-SmCo Magnets, zinozibuthe wemvelo futhi zibonisa imiphumela ehlukahlukene kazibuthe. Bayakwazi ukukhiqiza amandla kazibuthe wezinhlelo zokusebenza ezifana namamotho, imishini kazibuthe, izinzwa, namadivayisi we-microwave, phakathi kokunye. Ngokusebenza njengendlela yokudlulisa nokuguqula amandla kazibuthe abe amandla emishini namandla kagesi, izinto zikazibuthe zenza kube lula ukulawula futhi kuzuzwe imiphumela oyifunayo.
Ama-SmCo Magnets ayalingana ngamandlaI-Neodymium Magnetskodwa abe nokumelana nezinga lokushisa eliphezulu nokuphoqelela. Ama-SmCo Magnes ayisinqumo esikhethwayo sezinhlelo zokusebenza zemoto ezidinga kakhulu ngenxa yokumelana kwazo okuqinile nemithelela ye-demagnetization kanye nokuzinza okuhle kakhulu kokushisa. Njengama-Neodymium Magnets, i-SmCo Magnes nayo idinga ukumbozwa ukuvimbela ukugqwala. Kodwa-ke, ukumelana kwayo nokugqwala kungcono kakhulu kunokwe-NdFeB. Ezimweni ezine-acidic, i-SmCo Magnes kusafanele imbozwe. Ukumelana nokugqwala kwayo kunikeza isiqinisekiso kulabo abacabanga ukusebenzisa omazibuthe ezinhlelweni zezokwelapha.
I-NdFeB Magnet yenza kahle emazingeni okushisa aphansi, kuyilapho i-SmCo Magnet yenza kahle emazingeni okushisa aphezulu. Ozibuthe be-Neodymium Iron Boron Magnets bangozibuthe abaqine kakhulu abangapheli ekamelweni lokushisa futhi bafika cishe ku-230 degrees Celsius, abalinganiswa ngozibuthe wabo oyinsalela we-Br. Kodwa amandla abo ehla ngokushesha ngokukhuphuka kwezinga lokushisa. Lapho izinga lokushisa lokusebenza lifinyelela ku-230 degrees Celsius, ukusebenza kwezibuthe ze-samarium cobalt kuqala ukudlula lokho kwe-NdFeB.
I-SmCo Magnet iyinto yesibili enamandla kazibuthe enekhono elihle kakhulu lokulwa nokukhishwa kazibuthe, esetshenziswa kabanzi embonini ye-aerospace noma izimboni lapho ukusebenza kubaluleke kakhulu futhi izindleko zisesibili. Ama-SmCo Magnets athuthukiswe ngawo-1970 anamandla kunawoOzibuthe BeCeramics (Ferrite Magnets)futhiIzibuthe ze-Aluminium Nickel Cobalt (Ozibuthe be-AlNiCo), kodwa hhayi njengokuqina njenge-Neodymium Magnets. Ama-Samarium Cobalt Magnets ahlukaniswe ikakhulukazi izigaba ezimbili, ahlukaniswe ububanzi bamandla. Ibanga lomkhiqizo wamandla weqembu lokuqala i-Sm1Co5 (eyaziwa nangokuthi 1-5) kanye nobubanzi beqembu lesibili i-Sm2Co17 (2-17).
I-Honsen Magneticsikhiqiza izinhlobo ezahlukene zeOzibuthe be-SmCo5 kanye ne-Sm2Co17.
Ukukhiqiza Inqubo SmCo Magnets
Ama-SmCo Magnets kanye Neodymium Magnets abelana ngenqubo yokukhiqiza efanayo. Ziqala njengezinsimbi eziyimpuphu, ezixutshwa futhi zihlanganiswe ngaphansi kwensimu enamandla kazibuthe. Izinto ezihlanganisiwe zibe sezifakwa emanzini ukuze kwakhiwe omazibuthe abaqinile. Uma kuziwa ekwenziweni komshini, zombili izinto zenza kube nesidingo sokusebenzisa amathuluzi edayimane, imishini yokukhipha ugesi, noma ukugaya okuhuquzelayo. Lezi zinqubo zibalulekile ukuze kuzuzwe umumo oyifunayo kanye nobukhulu odonsa. Inqubo yokukhiqiza omagnethi be-SmCo (Samarium Cobalt) ibandakanya izinyathelo ezimbalwa:
Inqubo yempushana→ Ukucindezela→ I-Sintering → Ukuhlolwa kwempahla kazibuthe → ukusika → imikhiqizo eqediwe
Ama-SmCo Magnets avame ukucutshungulwa ngaphansi kwezimo ezingenazibuthe, ngesondo lokugaya idayimane kanye nokugaya okumanzi, okudingekayo. Ngenxa yokushisa okuphansi kokushisa, i-SmCo Magnets akumele yome ngokuphelele. Inhlansi encane nje noma ugesi omile okhiqizwayo ungavusa kalula umlilo, ngezinga lokushisa eliphakeme kakhulu, okunzima ukulilawula.
Izici Eziyisisekelo SmCo Magnets
I-Demagnetization inzima kakhulu ku-samarium-cobalt
Omazibuthe be-SmCo bazinzile izinga lokushisa.
Ayabiza futhi angaphansi kokuguquguquka kwentengo (i-cobalt izwela intengo yemakethe).
Ozibuthe baseSamarium-cobalt banokugqwala okuphezulu kanye nokumelana ne-oxidation, abavamile ukumbozwa futhi bangase baqashwe.
Ozibuthe be-Samarium-cobalt bantekenteke futhi baqhekeka kalula futhi baqhekezwe.
Ozibuthe be-Samarium Cobalt abafakwe i-sintered babonisa i-anisotropy kazibuthe, ekhawulela ukuqondiswa kukazibuthe ku-eksisi yokuma kwawo kukazibuthe. Lokhu kufezwa ngokuvumelanisa isakhiwo sekristalu yezinto njengoba senziwa.
SmCo Magnets VS Sintered NdFeB Magnets
Okulandelayo umehluko omkhulu phakathi kozibuthe be-NdFeB abahlanganisiwe kanye nozibuthe be-SmCo:
1. Amandla kazibuthe:
Amandla kazibuthe we-Permanent Neodymium Magnet makhulu kunalawo we-SmCo Magnet. I-Sintered NdFeB ine-(BH)Max efika ku-55MGOe, kanti impahla ye-SmCo ine-(BH)Max engu-32MGOe. Uma kuqhathaniswa nempahla ye-NdFeb, impahla ye-SmCo ingcono ekumelaneni ne-demagnetization.
2. Ukumelana nezinga lokushisa eliphezulu
Mayelana nokumelana nezinga lokushisa eliphezulu, i-NdFeB ayingcono kune-SmCo. I-NdFeB ingakwazi ukumelana namazinga okushisa afika ku-230 °C kuyilapho i-SmCo ikwazi ukumelana nezinga lokushisa elifinyelela ku-350 °C.
3. Ukumelana nokugqwala
Ozibuthe be-NdFeB bazabalaza ukumelana nokugqwala kanye ne-oxidation. Ngokuvamile, zidinga ukupuletiswa noma zifakwe nge-vacuum ukuze zivikeleke. I-Zinc, i-nickel, i-epoxy, nezinye izinto zokumboza zivame ukusetshenziswa. Izibuthe ezenziwe nge-SmCo ngeke zigqwale.
4. Isimo, inqubo, kanye nokuhlanganisa
Ngenxa yobuthaka bazo, i-NdFeb ne-SmCo azikwazi ukukhiqizwa kusetshenziswa izinqubo zokusika ezijwayelekile. Isondo ledayimane kanye nokusika kwe-electrode yocingo yizindlela ezimbili eziyinhloko zokucubungula. Lokhu kunciphisa izinhlobo zalezi zidonsa ezingase zikhiqizwe. Izimo eziyinkimbinkimbi kakhulu azikwazi ukusetshenziswa. Izinto ze-SmCo zibhibha futhi ziphuka uma kuqhathaniswa nezinye izinto. Ngakho-ke, lapho wakha futhi usebenzisa omagnethi be-SmCo, sicela uqaphe ngokwedlulele.
5. Inani
Ozibuthe be-SmCo babebiza ngokuphindwe kabili uma bengabizi ngokuphindwe kathathu, njengozibuthe be-NdFeB eminyakeni embalwa edlule. Ngenxa yezinqubomgomo ezivimbelayo zezwe ezimayini ezingavamile, intengo ye-NdFeB inyuke kakhulu eminyakeni yamuva. Empeleni, omazibuthe be-NdFeB abajwayelekile babiza kancane kune-samarium cobalt.
Izicelo SmCo Magnets
Imelana ngokuqinile nokugqwala kanye ne-oxidation, iSmCo Magnets ithola ukusetshenziswa okubanzi emikhakheni yezindiza, i-aerospace, ukuvikela izwe, kanye nezempi, kanye nokukhiqizwa kwezingxenye ze-microwave, imishini yokwelapha, izinsimbi, kanye nemishini, kanye nezinhlobo ezihlukahlukene. yezinzwa kazibuthe, amaprosesa, amamotho, kanye nozibuthe abaphakamisayo. Ukusetshenziswa okufanayo kwezimboni kwe-NdFeB kufaka phakathi amaswishi, izipikha, izinjini zikagesi, izinsimbi, nezinzwa.
KUNGANI SIKHETHE
Ngaphezu kweminyaka eyishumi,I-Honsen Magneticsuphumelele kakhulu ekukhiqizeni nasekuhwebeniOzibuthe Abahlala PhakadefuthiImihlangano Yezibuthe. Imigqa yethu yokukhiqiza ihlanganisa izinqubo ezibalulekile ezinjengomshini, ukuhlanganisa, ukushisela, nokubumba umjovo, okusivumela ukuthi sinikeze isisombululo esibanzi kumakhasimende ethu. Ngamakhono ethu abanzi, siyakwazi ukukhiqiza imikhiqizo yekhwalithi ephezulu ehlangabezana namazinga aphezulu.
