Samarium Cobalt Magnets Magnets, hu ua SmCo hlau nplaum, yog thawj cov khoom siv hlau nplaum uas siv los ua lag luam. Zoo li NdFeB hlau nplaum, nws yog ib hom khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb. Txawm li cas los xij, lawv tus kheej cov khoom sib nqus sib txawv heev ntawm cov hlau nplaum NdFeB. Tab sis kev khiav hauj lwm kub ntau yog dav, nrog superior kub coefficient thiab muaj zog corrosion kuj. Samarium cobalt hlau nplaum yuav yeej ua haujlwm ntawm qhov kub thiab txias thiab yuav pib ua haujlwm tshwj xeeb ntawm cov hlau nplaum kub neodymium los ntawm 150 degrees Celsius mus ntxiv.
Samarium cobalt hlau nplaum tsis tsuas yog ua tau zoo ntawm qhov kub thiab txias, tab sis kuj tseem khaws lawv cov hlau nplaum txawm tias qhov kub thiab txias qis dua xoom ({0}} degrees Celsius), ua rau lawv nrov rau cov ntawv thov cryogenic. Txawm hais tias nws muaj qhov kub thiab txias ntau dua thiab tiv taus corrosion.
SmCo hlau nplaum ua haujlwm qib
Muaj ob hom tseem ceeb ntawm samarium cobalt hlau nplaum, thiab muaj ntau qib hauv txhua hom. Lub zog siab tshaj plaws ntawm samarium cobalt hlau nplaum yog li ntawm 15MGOe mus rau 32MGOe. Hauv kev sib piv, cov khoom lag luam muaj zog tshaj plaws muaj cov hlau nplaum muaj zog tshaj plaws ntawm 52 MGOe.
Ob hom samarium cobalt hlau nplaum yog Sm1Co5 thiab Sm2Co17, tab sis lawv feem ntau hu ua 1-5 thiab 2-17. Cov khoom siv hluav taws xob siab tshaj plaws ntawm 1-5 series yog 15 txog 24MGOe, thiab qhov siab tshaj plaws ua haujlwm kub yog 250 degrees Celsius. Cov khoom siv hluav taws xob siab tshaj plaws ntawm 2-17 series yog nyob nruab nrab ntawm 22 thiab 32 MGOe, thiab qhov siab tshaj plaws ua haujlwm kub yog 350 degrees Celsius.
SmCo hlau nplaum kev ua tau zoo parameter cov lus
Koj tuaj yeem xa mus rau qhov kev ua haujlwm parameter ntawm samarium cobalt hlau nplaum hauv qab no. Nws yog ib qho tseem ceeb uas yuav tsum nkag siab txog ob hom samarium cobalt hlau nplaum thiab qhov kub thiab txias tsis kam, uas yuav pab tau peb xaiv cov khoom tsim nyog ntawm samarium cobalt hlau nplaum. Feem ntau ntawm 2-17 hom SmCo hlau nplaum yog nyob rau hauv kev lag luam lag luam tam sim no, thiab muaj tsawg heev 1-5 SmCo hlau nplaum tsim.
Vim lawv cov thermal stability, lawv yog cov hlau nplaum ntawm kev xaiv rau ntau daim ntawv thov xws li hluav taws xob motors thiab generators nyob rau hauv manufacturing, automotive thiab aerospace industries. Samarium cobalt hlau nplaum kuj tseem tiv taus corrosion thiab demagnetization rog dua li cov hlau nplaum neodymium vim tias lawv muaj cov hlau me me los yog tsis muaj hlau. Txawm li cas los xij, zoo li cov hlau nplaum neodymium, lawv yog cov tawv heev thiab nkig heev, uas txhais tau hais tias lawv muaj feem cuam tshuam thiab tawg yog tias lawv tuaj rau hauv kev sib tsoo ncaj qha nrog cov hlau tawv.
Vim yog tus nqi ntawm kev tsim SmCo hlau nplaum, qhov tsis zoo ntawm SmCo hlau nplaum yog lawv cov nqi siab piv rau cov hlau nplaum Neodymium. Vim lawv cov khoom, cov hlau nplaum samarium cobalt feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau ua haujlwm kub xws li cov tshuab hluav taws xob, twj tso kua mis txuas, sensors, hluav taws xob motors, marine daim ntawv thov nrog rau tsheb, aerospace, tub rog, khoom noj khoom haus thiab kev tsim khoom.
Cov ntsiab lus: Yog tias qhov xav tau ntawm qhov kub thiab txias, koj tuaj yeem xaiv cov hlau nplaum SmCo, thiab yog tias koj muaj cov hlau nplaum sib nqus, xaiv NdFeB hlau nplaum.
