Samarium cobalt hlau nplaum yog lub ntiaj teb tsis tshua muaj cov khoom siv hlau nplaum ruaj khov nrog lub cev tshwj xeeb thiab ntau yam kev siv. Hauv qab no, peb yuav muab cov ncauj lus kom ntxaws txog cov yam ntxwv tshwj xeeb thiab kev paub txog ntawm samarium cobalt hlau nplaum.
Ua ntej, samarium cobalt hlau nplaum muaj cov khoom sib nqus zoo heev. Nws muaj lub sijhawm sib nqus siab thiab coercivity, thiab tuaj yeem tsim kom muaj zog sib nqus. Piv rau lwm cov khoom siv hlau nplaum ruaj khov, samarium cobalt hlau nplaum muaj cov khoom siv hluav taws xob ntau dua, ua rau lawv siv dav hauv cov ntawv thov uas xav tau lub zog sib nqus. Samarium cobalt hlau nplaum kuj muaj siab coercivity, uas txhais tau hais tias lawv muaj peev xwm tiv thaiv demagnetization, ua rau lawv tsis tshua muaj peev xwm poob lawv cov hlau nplaum hauv kev siv.
Qhov thib ob, cov qauv sib nqus sib nqus ntawm samarium cobalt hlau nplaum yog qhov tshwj xeeb. Sib Nqus domains yog cov cheeb tsam sib nqus uas muaj ntau ntawm cov khoom sib nqus, uas yog cov hauv paus rau cov khoom sib nqus mus tas li kom tau txais cov hlau nplaum. Nyob rau hauv samarium cobalt hlau nplaum, muaj ib tug siab domain phab ntsa zog ntawm lub magnetic siv lead ua domains, yog li nws muaj ib tug siab tsis kam mus magnetic domain decomposition kub. Qhov no txhais tau hais tias samarium cobalt hlau nplaum tseem tuaj yeem tswj cov hlau nplaum zoo hauv qhov chaw kub kub, uas yog qhov tseem ceeb rau qee qhov kev siv kub.
Tsis tas li ntawd, samarium cobalt hlau nplaum kuj muaj qhov zoo corrosion kuj. Vim nws cov ntsiab lus tseem ceeb yog cov ntsiab lus tsis tshua muaj hauv ntiaj teb, samarium cobalt hlau nplaum muaj qhov ua haujlwm zoo rau qee cov kua qaub-puag corrosion. Vim muaj cov ntsiab lus tsis tshua muaj hauv ntiaj teb, samarium cobalt hlau nplaum yog nquag tsim cov yeeb yaj kiab passivation hauv oxidizing ib puag ncig, uas tuaj yeem tiv thaiv qhov chaw ntawm cov hlau nplaum thiab txo qhov kev pheej hmoo ntawm corrosion. Qhov no ua rau samarium cobalt hlau nplaum muaj peev xwm siv tau hauv qee qhov chaw tshwj xeeb, xws li kev ntsuas dej hiav txwv, kev tshawb nrhiav roj thiab lwm qhov chaw.
Tsis tas li ntawd, samarium cobalt hlau nplaum kuj muaj qhov sib nqus sib nqus sib nqus sib nqus induction siv. Sib nqus saturation magnetic induction intensity yog qhov taw qhia tseem ceeb hauv cov khoom siv hlau nplaum ruaj khov, sawv cev rau qhov siab tshaj plaws sib nqus induction siv uas cov khoom tuaj yeem tsim. Qhov sib nqus saturation sib nqus induction siv ntawm samarium cobalt hlau nplaum yog qhov siab, ncav cuag 1.2-1.45 Tesla, uas muaj txiaj ntsig zoo hauv ntau yam kev siv hlau nplaum. Qhov no kuj yog ib qho ntawm cov laj thawj tseem ceeb vim li cas samarium cobalt hlau nplaum tuaj yeem siv dav hauv thaj chaw xws li motors, generators, thiab induction cua sov.
Ntxiv rau cov yam ntxwv no, samarium cobalt hlau nplaum kuj muaj qee qhov tshwj xeeb. Piv txwv li, samarium cobalt hlau nplaum muaj kev ruaj ntseg zoo thiab ua haujlwm ntev, thiab tsis yooj yim rau cov hlau nplaum tawg thaum siv mus ntev. Nws cov khoom siv tshuaj yog ruaj khov thiab tsis yooj yim oxidized los yog decomposed. Tsis tas li ntawd, cov txheej txheem kev npaj ntawm samarium cobalt hlau nplaum yog qhov paub tab, thiab cov khoom sib nqus zoo tshaj plaws tuaj yeem tau txais los ntawm kev tsim nyog sintering thiab kev kho cua sov.
Hauv cov ntsiab lus, samarium cobalt hlau nplaum muaj cov khoom sib nqus tshwj xeeb, kev tiv thaiv corrosion, cov qauv sib nqus sib nqus, thiab sib nqus saturation sib nqus induction siv. Qhov no ua rau samarium cobalt hlau nplaum ua tau zoo nyob rau hauv ntau yam kev siv xws li siab sib nqus zog, siab kub, thiab corrosive ib puag ncig, thiab muaj ntau yam ntawm daim ntawv thov kev cia siab. Samarium cobalt hlau nplaum yog dav siv nyob rau hauv teb xws li motors, generators, induction cua sov, sensors, thiab sib nqus tub yees. Nyob rau hauv lub neej yav tom ntej, nrog rau txoj kev loj hlob ntawm cov cuab yeej technology thiab kev xav tau ntawm cov hlau nplaum ua tau zoo, samarium cobalt hlau nplaum yuav tsum tau siv rau hauv ntau lub teb thiab coj tau yooj yim dua thiab txoj hauv kev loj hlob rau tib neeg lub neej.
