Iimagnethi zeSamarium Cobalt (SmCo).
Iimagnethi ze-Samarium Cobalt (i-SmCo Magnets) luhlobo lwezinto ezisebenza ngokusisigxina umazibuthe. Zenziwa kusetyenziswa i-metallic samarium, i-cobalt, kunye nezinye iintsimbi ezinqabileyo, ezizenza zibe zezona zinto zixabisa kakhulu ukuvelisa. Inkqubo yokwenziwa kwemveliso ibandakanya ukunyibilika, ukugaya, ukucinezela, kunye ne-sintering, okukhokelela kwiipropati ezahlukeneyo kunye namanqanaba emagnethi. Enye inzuzo ephawulekayo yeemagnethi ze-SmCo kukuxhathisa kwabo okuphezulu kwi-corrosion, kunye nokukwazi kwabo ukumelana nobushushu obuphezulu, ukufikelela kwi-350 °C, kwaye ngamanye amaxesha kunye ne-500 °C. Oku kuxhathisa ubushushu kubenza bahluke kwezinye iimagnethi ezisisigxina ezinonyamezelo olusezantsi kumaqondo obushushu agqithisileyo, enika iimagnethi ze-SmCo umphetho obalulekileyo.
Njengokuchazwa kwabathengi, ii-roughcasts ze-SmCo Magnets ziya kuqhubekekiswa ngoomatshini ukufikelela kwiimilo kunye nobukhulu obufunwayo. Ngaphandle kokuba uyalelwe ngenye indlela ngumthengi, iimveliso zokugqibela ziya kwenziwa zimagnethi. Izixhobo zemagneti, ezinje ngeSmCo Magnets, zinemagnethi engokwemvelo kwaye zibonisa iziphumo ezahlukeneyo zemagnethi. Bayakwazi ukuvelisa amandla kazibuthe kwizicelo ezinje ngeenjini, oomatshini bemagnethi, abenzi boluvo, kunye nezixhobo zemicrowave, phakathi kwabanye. Ngokusebenza njengesixhobo sokudlulisa kunye nokuguqula amandla emagnethi abe ngamandla oomatshini kunye namandla ombane, imathiriyeli yemagnethi iququzelela ulawulo kunye nokufezekisa iziphumo ezinqwenelekayo.
SmCo Magnets zilingana ngamandla ukubaNeodymium Magnetskodwa ube nokumelana nobushushu obuphezulu kunye nokunyanzeliswa. I-SmCo Magnes lolona khetho lukhethwayo kwezona zicelo zemoto zifuna kakhulu ngenxa yokuchasa okunamandla kwiimpembelelo ze-demagnetization kunye nozinzo olubalaseleyo lobushushu. NjengooMazibuthe beNeodymium, iSmCo Magnes nayo ifuna iingubo zokuthintela umhlwa. Nangona kunjalo, ukumelana kwayo nomhlwa kubhetele kakhulu kunoko kwe-NdFeB. Kwiindawo ezineasidi, iSmCo Magnes kufuneka isagqunywe. Ukunganyangeki komhlwa kukwabonelela ngesiqinisekiso kwabo bacinga ukusebenzisa iimagnethi kwizicelo zonyango.
NdFeB Magnet iqhuba kakuhle kumaqondo obushushu asezantsi, ngelixa SmCo Magnet iqhuba kakuhle kumaqondo obushushu aphezulu. I-Neodymium Iron Boron Magnets zezona magnethi zomeleleyo zisisigxina kwiqondo lobushushu begumbi ukuya kuthi ga kwiqondo lama-230 ngokukaCelsius, zilinganiswe ngozibuthe wazo oshiyekileyo weBr. Kodwa amandla abo ayancipha ngokukhawuleza ngokunyuka kweqondo lokushisa. Xa ubushushu bokusebenza busondela kwi-230 degrees Celsius, ukusebenza kweemagnethi ze-cobalt ze-samarium ziqala ukugqithisa i-NdFeB.
I-SmCo Magnet yinto yesibini eyomeleleyo yemagnethi enobuchule obugqwesileyo bokuchasa umbane, isetyenziswa kakhulu kwishishini le-aerospace okanye amasimi oshishino apho ukusebenza kuphambili kwaye iindleko zisesekondari. I-SmCo Magnets ephuhliswe kwi-1970s yomelele kuneIimagnethi zeCeramics (iFerrite Magnets)kwayeIimagnethi ze-Aluminiyam yeNikel yeCobalt (i-AlNiCo Magnets), kodwa ayinamandla njengeNeodymium Magnets. I-Samarium Cobalt Magnets ihlulwe kakhulu ibe ngamacandelo amabini, ahlulwe ngoluhlu lwamandla. Uluhlu lwemveliso yamandla yeqela lokuqala i-Sm1Co5 (eyaziwa nangokuthi i-1-5) kunye noluhlu lweqela lesibini Sm2Co17 (2-17).
Honsen Magneticsivelisa iintlobo ngeentlobo zeSmCo5 kunye Sm2Co17 iimagnethi.
Inkqubo yokwenziwa kweSmCo Magnets
I-SmCo Magnets kunye ne-Neodymium Magnets yabelana ngenkqubo yokuvelisa efanayo. Ziqala njengomgubo wesinyithi, oxutywe kwaye udityaniswe phantsi komhlaba owomeleleyo wemagnethi. Iimathiriyeli ezidityanisiweyo ziye zitshiswe ukuze zenze iimagnethi eziqinileyo. Xa kufikwa kumatshini, zombini izixhobo zenza kube yimfuneko ukusetyenziswa kwezixhobo zedayimani, ukukhutshwa kombane, okanye ukugawula ngokurhabaxa. Ezi nkqubo zibalulekile ekufezekiseni imilo efunekayo kunye nemilinganiselo yemagnethi. Inkqubo yokwenziwa kwemagnethi ye-SmCo (Samarium Cobalt) ibandakanya amanyathelo aliqela:
Inkqubo yomgubo→ Ukucofa→ Ukucofa → Uvavanyo lwepropathi yemagneti → ukusika → iimveliso ezigqityiweyo
Iimagnethi ze-SmCo zidla ngokucutshungulwa phantsi kweemeko ezingenazibuthe, kunye nevili lokusila idayimani kunye nokusila okumanzi, okuyimfuneko. Ngenxa yobushushu obuphantsi bokutshisa, ii-SmCo Magnets akufuneki zome ngokupheleleyo. Intlantsi nje encinci okanye umbane ongashukumiyo kwimveliso unokuvusa ngokulula umlilo, ngobushushu obuphezulu kakhulu, ekunzima ukuwulawula.
Iimpawu eziphambili zeSmCo Magnets
I-Demagnetization inzima kakhulu kwi-samarium-cobalt
Iimagnethi ze-SmCo zizinzile ubushushu.
Ziyabiza kwaye zixhomekeke ekutshintsheni kwexabiso (i-cobalt inovakalelo lwexabiso lemarike).
Iimagnethi ze-Samarium-cobalt zine-corrosion ephezulu kunye nokumelana ne-oxidation, azifane zigqunywe kwaye zinokuqashwa.
Iimagnethi zeSamarium-cobalt zibuthathaka kwaye ziqhekeka ngokulula kwaye ziqhekeke.
I-Samarium Cobalt Magnets eziye zaphonswa zibonisa i-anisotropy magnetic, ethintela ulwalathiso lwemagneti ukuya kwi-axis ye-orientation yabo magnetic. Oku kufezwa ngokulungelelanisa ubume bekristale bezinto njengoko benziwa.
SmCo Magnets VS Sintered NdFeB Magnets
Oku kulandelayo ngowona mahluko uphambili phakathi kweemagnethi ze-NdFeB kunye neemagnethi ze-SmCo:
1. Amandla emagnethi:
Amandla kazibuthe weMagnet yeNeodymium eSisigxina mkhulu kunalowo weSmCo Magnet. I-Sintered NdFeB ine-(BH)Max ukuya kuthi ga kwi-55MGOe, kanti imathiriyeli ye-SmCo ine-(BH)Max ye-32MGOe. Xa kuthelekiswa nezinto eziphathekayo ze-NdFeb, izinto ze-SmCo zingcono ekuxhathiseni ukukhutshwa kweemagneti.
2. Ukumelana nobushushu obuphezulu
Ngokumalunga nokumelana nobushushu obuphezulu, i-NdFeB ayikho ngcono kune-SmCo. I-NdFeB inokumelana namaqondo obushushu ukuya ku-230 °C ngelixa i-SmCo ikwazi ukumelana namaqondo obushushu ukuya kuma-350 °C.
3. Ukumelana nokubola
Iimagnethi ze-NdFeB ziyasokola ukumelana nomhlwa kunye ne-oxidation. Ngokuqhelekileyo, kufuneka zibekwe okanye zifakwe kwi-vacuum ukuze zikhuseleke. Zinc, nickel, epoxy, kunye nezinye izinto zokugquma zisetyenziswa rhoqo. Iimagnethi ezenziwe nge-SmCo aziyi kugqwala.
4. Ubume, inkqubo, kunye nokudibanisa
Ngenxa yobuthathaka babo, i-NdFeb kunye ne-SmCo ayikwazi ukuveliswa ngokusebenzisa iinkqubo zokusika eziqhelekileyo. Ivili ledayimani kunye nokusika i-electrode yocingo zezona ndlela zimbini zokucwangcisa. Oku kunciphisa iifom zezi magnethi ezinokuveliswa. Iimilo ezintsonkothileyo kakhulu azinakusetyenziswa. Imathiriyeli ye-SmCo inobunkunkqele kwaye yophuka xa ithelekiswa nezinye izinto. Ke ngoko, xa usakha kwaye usebenzisa iimagnethi zeSmCo, nceda ulumke kakhulu.
5. Ixabiso
Iimagnethi ze-SmCo zazibiza ngokuphindwe kabini ukuba azibizi ngokuphindwe kathathu, njengemagnethi ye-NdFeB kwiminyaka embalwa edlulileyo. Ngenxa yemigaqo-nkqubo ethintelayo yelizwe kwimigodi enqabileyo yomhlaba, ixabiso le-NdFeB linyuke kakhulu kwiminyaka yakutshanje. Ngokwenyani, iimagnethi zeNdFeB eziqhelekileyo zibiza kancinci kunesamarium cobalt.
Usetyenziso lweeMaginethi ze-SmCo
Ixhathisa kakhulu kwi-corrosion kunye ne-oxidation, i-SmCo Magnets ifumana ukusetyenziswa okubanzi kwimimandla ye-aviation, i-aerospace, ukhuselo lwesizwe, kunye nomkhosi, kunye nokuveliswa kwamacandelo e-microwave, izixhobo zonyango, izixhobo kunye nezixhobo, kunye neentlobo ezahlukeneyo. yezinzwa zemagnethi, iiprosesa, iimotor, kunye neemagnethi zokuphakamisa. Usetyenziso olufanayo lwemizi-mveliso ye-NdFeB lubandakanya iiswitshi, isandisi-lizwi, iimoto zombane, izixhobo, kunye nezinzwa.
