Kev sib xyaw ntawmSamarium Cobalt Permanent Magnets
Samarium cobalt ruaj khov hlau nplaum yog lub ntiaj teb tsis tshua muaj hlau nplaum, feem ntau yog tsim los ntawm hlau samarium (Sm), hlau cobalt (Co), tooj liab (Cu), hlau (Fe), zirconium (Zr) thiab lwm yam khoom, los ntawm cov qauv muab faib ua 1. : 5 hom thiab 2: 17 hom ob, yog rau thawj tiam thiab tiam thib ob ntawm cov khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb.Samarium cobalt ruaj khov hlau nplaum muaj cov khoom sib nqus zoo heev (siab remanence, siab coercivity thiab siab magnetic zog khoom), tsis tshua muaj kub coefficient, siab kub kev pab cuam thiab muaj zog corrosion kuj, yog qhov zoo tshaj plaws kub resistant mus tas li hlau nplaum khoom, lug siv nyob rau hauv microwave li, electron. beam devices, high-power / high-speed motors, sensors, magnetic Cheebtsam thiab lwm yam lag luam.
Kev ua haujlwm ntawm 2:17 samarium-cobalt hlau nplaum
Ib qho ntawm cov hlau nplaum samarium-cobalt nrov tshaj plaws yog 2:17 samarium-cobalt hlau nplaum, cov hlau nplaum uas paub txog lawv cov khoom sib nqus zoo tshaj plaws, ua rau lawv thawj qhov kev xaiv rau cov ntawv thov uas xav tau siab sib nqus thiab ruaj khov.
Los ntawm cov yam ntxwv ntawm kev ua tau zoo, 2:17 samarium-cobalt cov hlau nplaum ruaj khov tuaj yeem muab faib ua cov kev ua haujlwm siab, kev ruaj ntseg siab series (tsis tshua muaj kub coefficient) thiab kub kub kuj series.Qhov tshwj xeeb ua ke ntawm kev sib nqus lub zog siab ntom ntom ntom ntom nti, ntsuas qhov ntsuas hluav taws xob zoo tshaj plaws rau cov khoom siv hluav taws xob
Qhov siab tshaj plaws sib nqus zog khoom ntawm txhua qib yog nyob nruab nrab ntawm 20-35MGOe, thiab qhov siab tshaj plaws ua haujlwm kub yog 500 ℃.Samarium-cobalt mus tas li hlau nplaum muaj qhov sib xyaw ua ke ntawm qhov kub tsis tshua muaj coefficient thiab zoo corrosion kuj, siab sib nqus zog ceev, kub stability thiab corrosion kuj, ua samarium-cobalt mus tas li hlau nplaum zoo tagnrho rau ntau yam kev siv, xws li hluav taws xob motors, sensors, magnetic. couplings thiab magnetic separators.
Cov khoom sib nqus ntawm samarium cobalt hlau nplaum ntawm qhov kub siab tshaj Ndfeb hlau nplaum yog li lawv tau siv dav hauv aerospace, tub rog teb, kub kub motors, tsheb sensors, ntau yam sib nqus drives, sib nqus twj thiab microwave.2:17 ibsamarium cobalt hlau nplaum yog cov nkig heev, tsis yooj yim rau kev ua cov duab los yog cov ntawv nyias nyias thiab nyias-walled rings, ntxiv rau, nws yog ib qho yooj yim los ua cov fab me me hauv cov txheej txheem tsim khoom, feem ntau yog tias nws tsis cuam tshuam rau cov khoom sib nqus lossis cov haujlwm, tuaj yeem suav tias yog cov khoom tsim nyog.
Nyob rau hauv cov ntsiab lus, samarium cobalt mus tas li hlau nplaum, tshwj xeeb tshaj yog cov high magnetic zog ceev seriesSm2Co17 hlau nplaum, muaj nuj nqis heev rau lawv cov khoom sib nqus zoo heev thiab ruaj khov.Lawv muaj peev xwm tiv taus qhov kub thiab txias ib puag ncig ua rau lawv yog thawj qhov kev xaiv rau kev thov kev thov thoob plaws kev lag luam.Raws li thev naus laus zis txuas ntxiv mus, qhov kev thov rau samarium-cobalt cov hlau nplaum ruaj khov yuav tsum loj hlob, ntxiv dag zog rau lawv txoj haujlwm ua ib feem tseem ceeb rau kev lag luam niaj hnub thiab kev lag luam.
