Ferrite Magnets tshuaj lom neeg
Cov hlau nplaum ferrite yog raug siab kub sintering kom tau ib qho kev microstructure. Kev ua tiav ntawm ferrite cov hlau nplaum nyob ntawm seb nws cov tshuaj lom neeg muaj pes tsawg leeg, tab sis kuj ua rau nws cov microstructure. Cov khoom sib txawv ntawm cov khoom ferrite nplua nuj muaj peev xwm muaj ntau yam sib txawv me me, yog tib qho feem ntawm cov khoom siv ferrite cov hlau, vim nws txawv cov txheej txheem sib txawv, lub microstructure tsis zoo li qub. Lub microstructure ntawm cov hlau nplaum ferrite yog ib qho kev qhia txog cov khoom ntawm cov khoom raw, zaub mov txawv thiab cov txheej txheem. Txoj kev tshawb ntawm cov microstructure ntawm ferrite tuaj yeem pab nrhiav kom txhob cuam tshuam cov txheej txheem, lub cev thiab kev quav tshuaj, nrhiav qhov teebmeem ntawm qhov teeb meem, los txhim kho cov txheej txheem ferrite, txhim kho cov khoom tsim thiab tsim muaj ntau yam tshiab Muab pov thawj. Cov nram qab no tsom rua kev siv lead ua loj hlob ntawm polycrystalline ferrite, microstructure tswj thiab lis-oriented ferrite npaj.
Microstructure ntawm Ferrite Magnets
Cov ferrite hlau nplaum muaj ntau cov ntsiab lus me me, thiab nws yeej muaj qhov xwm ntawm ntau cov ntaub ntawv. Feem ntau xa mus rau lub microstructure ntawm ferrite cov hlau nplaum, mas siv ntau yam kev soj ntsuam me me, nws tseem hu ua M microstructure. Cov qauv thiab kev taw qhia ntawm cov theem, qhov orientation, orientation lossis faib, qhov ntim ntawm qhov theem; qhov loj thiab zoo ntawm cov theem, Grain ciam qauv, muaj pes tsawg hloov, grain ciam precipitates thiab thiaj li nyob rau. Rau cov hlau nplaum sintered ferrite, nws yuav tsum tau ua ib theem xwb (los ntawm cov tshuaj siv pom ntawm cov tshuaj), yog li nyob rau hauv cov microstructure, cov khoom tsim nyog ntawm cov xim yog cov qoob loj, cov qauv, kev sib xyaw ua qauv theem, thiab cov khais loj Quantity thiab kev faib tawm.
Kev tshawb fawb ntawm kev xav tau tshwj xeeb cov cuab yeej siv, cov ntsiab cai yog siv cov ntau yam kev sib txawv ntawm electromagnetic los yog lwm yam thiab cov khoom tom qab sib cuam tshuam ntawm absorption, emission, polarization thiab cuam tshuam phenomena, los ntawm kev nkag siab ntawm cov ntaub ntawv ntawm cov khoom. Cov ntawv teev muaj qee qhov qauv ntawm txoj kev tshawb fawb thiab nws qhov kev txiav txim siab ntawm cov ntsiab lus.
Cov ntaub ntawv cov qauv thiab nws txoj kev txiav txim siab rau kev tshawb xyuas cov ntsiab lus kev txiav txim siab
Theem optical microscopy, electron microscopy, electron diffraction, X - hluav taws xob diffraction
Theem hloov microscopy, txawv thermal analysis, xoo hluav taws xob diffraction
Morphology ntawm kho qhov muag microscopy, electron microscopy
Chav tsev, chaw seem electron diffraction, neutron diffraction, X - hluav taws xob diffraction
Lattice symmetry pom thiab ntais nqus dej nqus spectra, X - ray emission thiab diffraction, txoj kev resonance.
