Hauv thaj tsam ntawm hluav taws xob engineering thiab hluav taws xob faib hluav taws xob, kev xaiv cov khoom siv tseem ceeb rau transformers thiab inductors plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov ua tau zoo thiab kev ua haujlwm ntawm cov khoom siv.Ob qhov kev xaiv nrov rau cov ntaub ntawv tseem ceeb yog amorphous core thiab nanocrystalline core, txhua qhov muab cov khoom tshwj xeeb thiab qhov zoo.Hauv tsab xov xwm no, peb yuav delve rau hauv cov yam ntxwv ntawm amorphous core thiab nanocrystalline core, thiab tshawb nrhiav qhov sib txawv ntawm ob.
Dab tsi yog Amorphous Core?
An amorphous coreyog ib hom ntawm cov khoom siv hlau nplaum uas yog tus cwj pwm los ntawm nws cov qauv tsis-crystalline atomic.Qhov tshwj xeeb atomic kev npaj no muab amorphous cores lawv cov khoom sib txawv, nrog rau cov tub ntxhais uas tsis muaj qhov poob, siab permeability, thiab cov khoom sib nqus zoo heev.Cov khoom siv feem ntau siv rau amorphous cores yog cov hlau-raws li alloy, feem ntau muaj cov khoom xws li hlau, boron, silicon, thiab phosphorus.
Qhov tsis-crystalline xwm ntawm amorphous cores tshwm sim nyob rau hauv random kev npaj ntawm atoms, uas tiv thaiv kev tsim ntawm magnetic domains thiab txo eddy tam sim no poob.Qhov no ua rau amorphous cores ua haujlwm tau zoo rau cov ntawv thov uas tsis tshua muaj zog poob thiab siab sib nqus permeability yog qhov tseem ceeb, xws li hauv cov hluav taws xob faib hluav taws xob thiab cov khoom siv hluav taws xob siab.
Amorphous cores yog tsim los siv cov txheej txheem ceev ceev, qhov twg cov molten alloy yog quenched ntawm tus nqi siab heev los tiv thaiv kev tsim ntawm crystalline lug.Cov txheej txheem no ua rau cov qauv atomic uas tsis muaj kev txiav txim ntev ntev, muab cov khoom siv nws cov khoom tshwj xeeb.
Nanocrystalline Core yog dab tsi?
Ntawm qhov tod tes, nanocrystalline core yog ib hom khoom siv hlau nplaum uas muaj nanometer-loj crystalline nplej embedded hauv amorphous matrix.Qhov no dual-theem qauv sib txuas cov txiaj ntsig ntawm ob qho tib si crystalline thiab amorphous cov ntaub ntawv, uas ua rau cov khoom sib nqus zoo heev thiab siab saturation flux ceev.
Nanocrystalline coresFeem ntau yog tsim los ntawm kev sib xyaw ntawm hlau, npib tsib xee, thiab cobalt, nrog rau me me ntxiv ntawm lwm cov ntsiab lus xws li tooj liab thiab molybdenum.Cov qauv nanocrystalline muab siab sib nqus permeability, qis coercivity, thiab superior thermal stability, ua rau nws haum rau high-power applications thiab high-frequency transformers.
Qhov sib txawv ntawm Amorphous Core thiab Nanocrystalline Core
Thawj qhov sib txawv ntawm amorphous cores thiab nanocrystalline cores nyob hauv lawv cov qauv atomic thiab ua rau cov khoom sib nqus.Thaum amorphous cores muaj cov qauv tsis-crystalline kiag li, nanocrystalline cores nthuav tawm cov qauv dual-theem muaj xws li nanometer-loj crystalline nplej hauv ib qho amorphous matrix.
Nyob rau hauv cov nqe lus ntawm magnetic zog,amorphous corespaub txog lawv qhov poob qis thiab siab permeability, ua rau lawv zoo tagnrho rau cov kev siv uas lub zog efficiency yog qhov tseem ceeb.Ntawm qhov tod tes, nanocrystalline cores muab ntau dua saturation flux ceev thiab superior thermal stability, ua rau lawv haum rau high-power thiab high-frequency daim ntaub ntawv.
Lwm qhov sib txawv tseem ceeb yog cov txheej txheem tsim khoom.Amorphous cores yog tsim los ntawm kev sib zog ceev ceev, uas cuam tshuam nrog quenching molten alloy ntawm tus nqi siab los tiv thaiv crystalline tsim.Nyob rau hauv sib piv, nanocrystalline cores feem ntau yog tsim los ntawm annealing thiab tswj crystallization ntawm amorphous ribbons, uas ua rau tsim ntawm nanometer-loj crystalline nplej nyob rau hauv cov khoom.
Kev txiav txim siab ntawm daim ntawv thov
Thaum xaiv ntawm amorphous cores thiab nanocrystalline cores rau ib daim ntawv thov tshwj xeeb, ntau yam yuav tsum tau xav txog.Rau cov ntawv thov uas tseem ceeb txo qis zog poob thiab kev ua haujlwm siab, xws li hauv cov khoom siv hluav taws xob faib hluav taws xob thiab cov inductors siab zaus, amorphous cores feem ntau yog qhov kev xaiv.Lawv cov tub ntxhais poob qis thiab siab permeability ua rau lawv zoo rau cov ntawv thov no, pab txhawb kev txuag hluav taws xob thiab txhim kho kev ua haujlwm.
Ntawm qhov tod tes, rau cov ntawv thov uas yuav tsum tau muaj kev ua kom muaj kuab paug siab, kev ruaj ntseg zoo dua, thiab muaj peev xwm tuav tau siab, nanocrystalline cores yog qhov tsim nyog dua.Cov khoom no ua rau nanocrystalline zoo tagnrho rau high-fais fab hloov khoom, thiab cov cuab yeej siv high
Hauv kev xaus, ob qho tib si amorphous cores thiab nanocrystalline cores muab cov txiaj ntsig tshwj xeeb thiab raug ua kom haum rau cov ntawv thov tshwj xeeb.Nkag siab txog qhov sib txawv ntawm lawv cov qauv atomic, cov khoom sib nqus, thiab cov txheej txheem tsim khoom yog qhov tseem ceeb rau kev txiav txim siab thaum xaiv cov khoom tseem ceeb rau transformers thiab inductors.Los ntawm kev siv cov yam ntxwv sib txawv ntawm txhua yam khoom siv, engineers thiab designers tuaj yeem ua kom zoo dua qhov kev ua tau zoo thiab kev ua haujlwm ntawm lawv lub zog faib thiab kev hloov pauv, thaum kawg pab txhawb kev nce qib hauv kev siv hluav taws xob thiab kev siv hluav taws xob ruaj khov.
