Kub kub resistant nplhaib SmCo hlau nplaum

SmCo hlau nplaum yog ib hom kev ua haujlwm siab tsis tshua muaj lub ntiaj teb ruaj khov hlau nplaum, uas tseem hu ua lub ntiaj teb tsis tshua muaj cobalt tsis tshua muaj ntiaj teb cov hlau nplaum ruaj khov. Qhov kev ua tau zoo ntawm SmCo hlau nplaum yog qhov zoo tshaj li cov khoom siv hlau nplaum ib txwm muaj ntawm cov khoom siv dav dav, thiab nws qhov seem sib nqus flux ntom ntom (Br) yog ntau dua 1.3 npaug ntawm hom dav dav, thiab nws lub zog quab yuam yog ntau tshaj 10 npaug. ntawm hom dav dav.SmCo hlau nplaum feem ntau muab faib ua ob pawg: SmCo5 thiab Sm2Co17. Tus qub yog ib yam khoom nyob ze-alpha ruaj khov hlau nplaum nrog Curie kub txog li 800 degree, thaum lub tom kawg yog ib hom ze-alpha-beta cov hlau nplaum ruaj khov nrog Curie kub txog li 1000 degree. Vim lub siab quab yuam ntawm chav tsev kub, SmCo hlau nplaum yuav siv tau nyob rau hauv high-end khoom uas yuav tsum tau kub kub kuj, siab siv thiab siab stability, xws li precision fais motors, generators, hluav taws xob relays, sib nqus bearings, hard drives, thiab lwm yam . SmCo hlau nplaum muaj qhov kub thiab txias ruaj khov thiab cov khoom siv hluav taws xob sib nqus zoo, thiab yog ib qho zoo tshaj plaws cov khoom siv hlau nplaum zoo tshaj plaws tam sim no paub.

Tsis tas li ntawd, SmCo hlau nplaum kuj muaj qhov zoo corrosion kuj thiab tuaj yeem siv rau hauv qhov chaw ntub dej. Txawm li cas los xij, vim yog tus nqi siab ntawm SmCo hlau nplaum, lawv daim ntawv thov raug txwv rau qee cov khoom siv high-end thiab cov cuab yeej precision. Tsis tas li ntawd, cov hlau nplaum tsawg thiab cov khoom siv siab ntawm SmCo hlau nplaum kuj txwv lawv daim ntawv thov. Yog li ntawd, txhawm rau nthuav dav daim ntawv thov ntau yam ntawm SmCo hlau nplaum, nws yog ib qho tsim nyog yuav tsum tau tshawb nrhiav thiab tsim cov thev naus laus zis tshiab los txo cov nqi tsim khoom thiab txhim kho cov txheej txheem ntau lawm.

Tam sim no, Tuam Tshoj tau tsim cov txheej txheem tshiab thiab cov khoom lag luam nrog cov khoom siv tau zoo thiab kev ua haujlwm zoo raws li kev paub txog SmCo5 thiab Sm2Co17 patents hauv Suav teb. Cov tsos ntawm cov khoom tshiab no tau txhim kho kev ua tau zoo / nqi piv ntawm SmCo hlau nplaum hauv Suav lag luam thiab tau qhib cov ntawv thov tshiab rau SmCo hlau nplaum hauv Suav lag luam. nyob rau hauv ntau yam hauj lwm. Piv txwv li, vim nws qhov kub thiab txias ruaj khov thiab cov khoom siv hluav taws xob sib nqus, SmCo hlau nplaum tuaj yeem siv los tsim cov khoom sib nqus rau cov cuab yeej kub thiab cov khoom siv. Tsis tas li ntawd, vim nws qhov zoo corrosion kuj, SmCo hlau nplaum tuaj yeem siv los tsim cov khoom siv hauv marine ib puag ncig, xws li cov cuab yeej tshawb fawb dej hiav txwv, cov khoom siv hauv hiav txwv, thiab lwm yam.

Lwm daim ntawv thov tseem ceeb ntawm SmCo hlau nplaum yog nyob rau hauv electroacoustic teb. Txij li thaum SmCo hlau nplaum muaj siab sib nqus permeability thiab sib nqus flux ceev, lawv tau siv dav hauv kev tsim cov khoom siv suab nrov thiab cov khoom siv suab nrov. Hauv cov khoom siv no, SmCo hlau nplaum yog siv los tsav thiab co lub suab coil, ua kom pom tseeb, tsis muaj suab nrov.

SmCo hlau nplaum kuj tseem siv rau hauv ntau yam kev siv thev naus laus zis xws li magnetic resonance imaging (MRI) machines, particle accelerators, electron microscopes, etc. kev tshawb fawb.

Zuag qhia tag nrho, txawm hais tias tus nqi tsim khoom ntawm SmCo hlau nplaum yog qhov siab, lawv tseem yog ib qho tseem ceeb heev uas tsis tshua muaj lub ntiaj teb cov hlau nplaum ruaj khov vim lawv cov kev ua tau zoo thiab ntau yam kev siv. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev tsim cov txheej txheem tshiab, kuv ntseeg tias yuav muaj ntau lub sijhawm yav tom ntej los txo cov nqi tsim khoom ntawm SmCo hlau nplaum, txhim kho lawv cov kev ua tau zoo, thiab yog li ntxiv nthuav lawv daim ntawv thov teb.
