Samarium Cobalt (SmCo) Magnets
Samarium Cobalt Magnets (SmCo Magnets) yog ib hom khoom siv hlau nplaum ruaj khov. Lawv tau tsim los siv hlau samarium, cobalt, thiab lwm yam hlau tsis tshua muaj, ua rau lawv cov khoom siv hlau nplaum kim tshaj plaws los tsim. Cov txheej txheem tsim khoom suav nrog melting, milling, nias, thiab sintering, uas ua rau cov khoom sib txawv thiab qib ntawm cov hlau nplaum. Ib qho txiaj ntsig tseem ceeb ntawm SmCo hlau nplaum yog lawv qhov siab tiv thaiv corrosion, nrog rau lawv lub peev xwm tiv taus qhov kub thiab txias, nce mus txog 350 ° C, thiab qee zaum txawm tias 500 ° C. Qhov ntsuas kub no ua rau lawv sib nrug los ntawm lwm cov hlau nplaum ruaj khov uas muaj qhov ua siab ntev rau qhov kub siab, muab SmCo cov hlau nplaum ib qho tseem ceeb.
Raws li ib tus neeg siv khoom tshwj xeeb, roughcasts ntawm SmCo Magnets yuav dhau los ua cov txheej txheem ua haujlwm kom tau txais cov duab thiab qhov ntau thiab tsawg. Tshwj tsis yog qhia lwm tus los ntawm cov neeg siv khoom, cov khoom kawg yuav raug magnetized. Cov ntaub ntawv sib nqus, xws li SmCo Magnets, muaj cov hlau nplaum uas muaj nyob hauv thiab nthuav tawm ntau yam sib nqus. Lawv muaj peev xwm tsim cov teb sib nqus rau cov ntawv thov xws li lub cev muaj zog, tshuab magnetic, sensors, thiab microwave, thiab lwm yam. Los ntawm kev ua raws li qhov nruab nrab rau kev hloov pauv thiab hloov lub zog sib nqus mus rau hauv lub zog hluav taws xob thiab hluav taws xob, cov khoom siv hlau nplaum pab tswj tau thiab ua tiav cov txiaj ntsig xav tau.
SmCo Magnets sib npaug ntawm lub zog rauNeodymium hlau nplaumtab sis muaj siab dua kub kuj thiab coercivity. SmCo Magnes yog qhov kev xaiv zoo tshaj plaws rau kev thov lub cev muaj zog tshaj plaws vim lawv muaj zog tiv thaiv kev cuam tshuam rau demagnetization thiab zoo thermal stability. Zoo li Neodymium Magnets, SmCo Magnes kuj xav tau cov txheej txheem los tiv thaiv corrosion. Txawm li cas los xij, nws qhov kev tiv thaiv corrosion yog qhov zoo dua li ntawm NdFeB. Hauv cov cheeb tsam acidic, SmCo Magnes tseem yuav tsum tau coated. Nws cov kev tiv thaiv corrosion kuj muab kev ruaj ntseg rau cov neeg xav siv cov hlau nplaum hauv cov ntawv kho mob.
NdFeB Magnet ua tau zoo ntawm qhov kub thiab txias, thaum SmCo Magnet ua tau zoo ntawm qhov kub siab dua. Neodymium Iron Boron Magnets yog cov hlau nplaum ruaj khov tshaj plaws nyob rau hauv chav tsev kub thiab txog li 230 degrees Celsius, ntsuas los ntawm lawv cov hlau nplaum seem Br. Tab sis lawv lub zog sai sai txo nrog nce kub. Thaum qhov kub ua hauj lwm nce mus txog 230 degrees Celsius, qhov kev ua tau zoo ntawm samarium cobalt hlau nplaum pib ua haujlwm zoo tshaj ntawm NdFeB.
SmCo Magnet yog qhov thib ob muaj zog sib nqus cov khoom uas muaj peev xwm tiv thaiv demagnetization zoo heev, dav siv hauv kev lag luam aerospace lossis kev lag luam kev lag luam uas qhov kev ua tau zoo yog qhov tseem ceeb thiab tus nqi thib ob. SmCo Magnets tsim nyob rau hauv 1970s muaj zog duaCeramics Magnets (Ferrite Magnets)thiabAluminium Nickel Cobalt Magnets (AlNiCo hlau nplaum), tab sis tsis muaj zog li Neodymium Magnets. Samarium Cobalt Magnets feem ntau muab faib ua ob pawg, muab faib los ntawm lub zog ntau. Cov khoom siv hluav taws xob ntau ntawm thawj pawg Sm1Co5 (tseem hu ua 1-5) thiab qhov ntau ntawm pawg thib ob Sm2Co17 (2-17).
Honsen Sib Nqustsim ntau yam ntawmSmCo5 thiab Sm2Co17 hlau nplaum.
Kev tsim cov txheej txheem ntawm SmCo Magnets
SmCo Magnets thiab Neodymium Magnets sib koom cov txheej txheem tsim khoom zoo sib xws. Lawv pib ua hmoov hlau, uas yog tov thiab compacted nyob rau hauv ib tug muaj zog magnetic teb. Cov ntaub ntawv compacted yog ces sintered los tsim cov hlau nplaum. Thaum nws los txog rau machining, ob cov ntaub ntawv yuav tsum tau siv cov cuab yeej pob zeb diamond, hluav taws xob tawm machining, los yog abrasive sib tsoo. Cov txheej txheem no yog qhov tseem ceeb rau kev ua tiav cov duab xav tau thiab qhov ntev ntawm cov hlau nplaum. Cov txheej txheem tsim khoom ntawm SmCo (Samarium Cobalt) hlau nplaum muaj ob peb kauj ruam:
Cov txheej txheem hmoov → Nias → Sintering → Sib nqus cov cuab yeej kuaj → txiav → cov khoom tiav
SmCo Magnets feem ntau ua tiav nyob rau hauv qhov xwm txheej tsis muaj hlau nplaum, nrog lub pob zeb diamond sib tsoo log thiab ntub zoo sib tsoo, uas yog qhov tsim nyog. Vim tias qhov kub tsis tshua muaj hluav taws kub, SmCo Magnets yuav tsum tsis txhob qhuav tag. Tsuas yog lub teeb me me lossis hluav taws xob zoo li qub hauv kev tsim khoom tuaj yeem ua rau hluav taws tau yooj yim, nrog rau qhov kub thiab txias, uas yog ib qho nyuaj rau tswj.
Cov yam ntxwv tseem ceeb ntawm SmCo Magnets
Demagnetization yog qhov nyuaj tshwj xeeb rau samarium-cobalt
SmCo hlau nplaum yog qhov kub thiab txias.
Lawv kim thiab raug tus nqi hloov pauv (cobalt yog tus nqi lag luam rhiab heev).
Samarium-cobalt hlau nplaum muaj kev tiv thaiv corrosion thiab oxidation, tsis tshua muaj coated thiab tej zaum yuav ua hauj lwm.
Samarium-cobalt hlau nplaum yog ib qho yooj yim tawg thiab tawg.
Samarium Cobalt Magnets uas tau sintered tso saib magnetic anisotropy, uas txwv cov kev taw qhia ntawm magnetization mus rau axis ntawm lawv magnetic orientation. Qhov no yog ua tiav los ntawm aligning cov khoom siv lead ua qauv raws li nws yog tsim.
SmCo Magnets VS Sintered NdFeB Magnets
Cov hauv qab no yog qhov sib txawv tseem ceeb ntawm sintered NdFeB hlau nplaum thiab SmCo hlau nplaum:
1. Magnetic quab yuam:
Lub zog sib nqus ntawm ib lub Neodymium Magnet ruaj khov yog ntau dua li ntawm SmCo Magnet. Sintered NdFeB muaj (BH) Max txog li 55MGOe, whereas SmCo cov khoom muaj (BH)Max ntawm 32MGOe. Piv rau cov khoom siv NdFeb, SmCo cov ntaub ntawv zoo dua ntawm kev tiv thaiv demagnetization.
2. Kub-kub kuj
Nyob rau hauv cov nqe lus ntawm high-kub kuj, NdFeB tsis zoo dua SmCo. NdFeB tuaj yeem tiv taus kub txog 230 ° C thaum SmCo tuaj yeem tiv taus qhov kub txog li 350 ° C.
3. Corrosion kuj
NdFeB hlau nplaum tiv thaiv corrosion thiab oxidation. Feem ntau, lawv yuav tsum tau plated lossis txawm tias lub tshuab nqus tsev los tiv thaiv lawv. Zinc, npib tsib xee, epoxy, thiab lwm yam ntaub ntawv txheej yog nquag siv. Cov hlau nplaum ua los ntawm SmCo yuav tsis xeb.
4. Puab, txheej txheem, thiab sib dhos
Vim lawv qhov fragility, NdFeb thiab SmCo tsis tuaj yeem tsim siv cov txheej txheem txiav. Pob zeb diamond log thiab hlau electrode txiav yog ob txoj kev ua haujlwm tseem ceeb. Qhov no txwv cov qauv ntawm cov hlau nplaum no uas yuav raug tsim tawm. Cov duab uas sib txawv heev tsis tuaj yeem siv. Cov khoom siv SmCo yog nkig thiab tawg tau txheeb ze rau lwm cov ntaub ntawv. Yog li ntawd, thaum tsim thiab siv SmCo hlau nplaum, thov ceev faj heev.
5. Nqe
SmCo hlau nplaum yog ob zaug li kim yog tias tsis yog peb zaug li kim, zoo li NdFeB hlau nplaum ob peb xyoos dhau los. Vim lub teb chaws txoj cai txwv tsis pub nyob rau hauv lub ntiaj teb tsis tshua muaj mining, tus nqi ntawm NdFeB tau nce ntau heev nyob rau xyoo tas los no. Hauv qhov tseeb, cov hlau nplaum NdFeB tsis tu ncua tsis tshua kim dua samarium cobalt.
Kev siv ntawm SmCo Magnets
Muaj zog tiv taus corrosion thiab oxidation, SmCo Magnets nrhiav kev siv dav hauv kev lag luam aviation, aerospace, kev tiv thaiv hauv tebchaws, thiab tub rog, nrog rau kev tsim cov khoom siv microwave, cov cuab yeej kho mob, cov cuab yeej, thiab cov cuab yeej, nrog rau ntau hom. ntawm magnetic sensors, processors, motors, thiab lifting magnets. Cov kev lag luam zoo sib xws rau NdFeB suav nrog cov keyboards, lub suab nrov, lub tshuab hluav taws xob, cov twj paj nruag, thiab cov sensors.
