Dab tsi yog qhov txawv ntawm neodymium hlau boron cov ntaub ntawv thiab cov ntaub ntawv ferrite

Muaj qhov sib txawv tseem ceeb ntawm cov ntaub ntawv neodymium hlau boron thiab cov ntaub ntawv ferrite hauv ntau yam:
Composition thiab formation:
NdFeB yog cov khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb uas muaj cov khoom xws li neodymium, hlau, thiab boron. Cov khoom no tau tshawb pom los ntawm Sumitomo Special Metal's Sanren Sagawa hauv xyoo 1982. Cov txheej txheem kev npaj tseem ceeb muaj xws li hmoov metallurgy, ceev solidification, thiab kev kho cua sov, ntawm cov hmoov metallurgy yog cov txheej txheem kev siv ntau tshaj plaws thiab paub tab.
Ferrite yog cov khoom siv hlau nplaum uas tsis yog xim hlau feem ntau yog tsim los ntawm hlau oxide thiab ib lossis ob peb lwm cov hlau oxides (xws li nickel oxide, zinc oxide, manganese oxide, thiab lwm yam) npaj thiab sintered. Nws cov txheej txheem ntau lawm thiab cov tsos zoo ib yam li ceramics, yog li nws tseem hu ua magnetic porcelain.
Cov tsos mob thiab kev kho deg:
Ferrite feem ntau yog qhov loj me me, muaj kev ntxhib los mos, thiab feem ntau tsis tas yuav electroplating. Nws cov xim ntuj yog xim dub.
Cov kev qhia tshwj xeeb ntawm neodymium hlau boron yog qhov me me, thiab txhawm rau tiv thaiv xeb, kev tiv thaiv xeb ntawm qhov chaw xws li npib tsib xee plating, zinc plating, lossis epoxy feem ntau yuav tsum tau ua.
Magnetic quab yuam thiab kev ua haujlwm:
Lub zog sib nqus ntawm ferrite feem ntau yog qhov qub thiab tsis muaj zog.
Neodymium hlau boron muaj zog sib nqus, muaj zog sib nqus khoom, siab coercivity, zoo stability, thiab zoo heev sib nqus zog, uas muaj peev xwm tswj tau siab magnetic zog ntawm chav tsev kub.
Nqe thiab Daim Ntawv Thov:
Tus nqi ntawm ferrite kuj pheej yig.
Tus nqi ntawm neodymium hlau boron nyob ntawm qhov kev ua tau zoo siv thiab yog tus nqi kim. Txawm li cas los xij, xav txog nws cov khoom siv hluav taws xob sib nqus, siab coercivity, zoo corrosion kuj, thiab zoo stability, neodymium hlau boron cov ntaub ntawv tam sim no yog ib qho ntawm cov khoom siv hlau nplaum ruaj khov, dav siv hauv cov teb xws li motors, electronics, kev sib txuas lus, kev kho mob, automotive, aerospace, thiab lwm yam.
Hauv cov ntsiab lus, muaj qhov sib txawv tseem ceeb ntawm cov ntaub ntawv neodymium hlau boron thiab cov ntaub ntawv ferrite nyob rau hauv cov nqe lus ntawm kev muaj pes tsawg leeg, zoo li, sib nqus quab yuam, nqi, thiab daim ntawv thov. Kev xaiv cov khoom siv yog nyob ntawm qhov kev thov tshwj xeeb scenario thiab cov kev xav tau.
