Cov ribbons Nanocrystalline thiab cov ribbons amorphous yog ob yam khoom siv uas muaj cov yam ntxwv tshwj xeeb thiab siv tau rau ntau qhov chaw. Ob qho ribbons no siv rau hauv ntau yam lag luam vim lawv cov yam ntxwv sib txawv, thiab kev nkag siab txog qhov txawv ntawm lawv yog qhov tseem ceeb rau kev siv lawv lub peev xwm kom zoo.
Nanocrystalline ribbon yog ib yam khoom siv uas muaj cov qauv sib txawv uas muaj cov noob me me uas siv lead ua. Cov noob no feem ntau me dua 100 nanometers hauv qhov loj me, ua rau cov khoom siv no muaj nws lub npe. Qhov loj me ntawm cov noob me me muab ntau yam zoo, xws li kev nkag tau zoo dua ntawm cov hlau nplaum, txo qis kev poob hluav taws xob, thiab kev ruaj khov thermal zoo dua. Cov khoom no ua raudaim kab xev nanocrystallineib yam khoom siv zoo heev rau kev siv hauv transformers, inductors, thiab magnetic cores.
Cov khoom siv sib nqus zoo dua ntawm cov nanocrystalline ribbons tso cai rau kev ua haujlwm zoo dua thiab lub zog ceev hauv transformers. Qhov no ua rau txo qis kev poob zog thaum lub sijhawm xa hluav taws xob thiab faib hluav taws xob, ua rau kev txuag hluav taws xob thiab kev txuag nqi. Kev ruaj khov thermal zoo dua ntawm cov nanocrystalline ribbons tso cai rau lawv kom tiv taus qhov kub siab dua yam tsis muaj kev puas tsuaj loj, ua rau lawv zoo tagnrho rau kev siv hauv cov chaw ua haujlwm hnyav.
Amorphous ribbon, ntawm qhov tod tes, yog cov khoom siv tsis-crystalline nrog cov qauv atomic tsis sib xws. Tsis zoo li nanocrystalline ribbons,daim kab xev amorphousstsis muaj cov ciam teb ntawm cov noob uas paub tseeb tab sis muaj cov qauv atomic sib xws. Cov qauv tshwj xeeb no muab cov ribbons amorphous nrog cov khoom sib nqus mos zoo heev, xws li coercivity qis, magnetization siab saturation, thiab poob qis.
Cov ntawv amorphous pom tau dav siv hauv kev tsim cov transformers muaj zog siab, cov sensors sib nqus, thiab cov ntaub thaiv hluav taws xob (EMI) shields. Vim lawv qhov poob qis ntawm cov tub ntxhais, cov ntawv amorphous muaj txiaj ntsig zoo hauv kev hloov lub zog hluav taws xob mus rau hauv lub zog sib nqus, ua rau lawv tsim nyog rau kev siv hluav taws xob zaus siab. Qhov coercivity qis ntawm cov ntawv amorphous tso cai rau kev yooj yim magnetization thiab demagnetization, yog li txo cov kev poob zog thaum lub sijhawm ua haujlwm.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm nanocrystalline thiab amorphous ribbons yog nyob rau hauv lawv cov txheej txheem tsim khoom. Nanocrystalline ribbons yog tsim los ntawm kev khov sai ntawm cov hlau molten, ua raws li kev tswj hwm annealing kom ua rau cov qauv crystalline xav tau. Ntawm qhov tod tes, amorphous ribbons yog tsim los ntawm kev txias sai ntawm cov hlau molten ntawm tus nqi ntawm lab degrees ib ob kom tiv thaiv kev tsim cov noob crystalline.
Ob qho tib si nanocrystalline thiab amorphous ribbons muaj lawv qhov tshwj xeeb hauv kev ua lag luam, ua kom tau raws li ntau yam kev xav tau ntawm kev lag luam. Kev xaiv ntawm cov ntaub ntawv no nyob ntawm qhov xav tau tshwj xeeb ntawm daim ntawv thov hauv kev ua haujlwm sib nqus, kev ruaj khov ntawm qhov kub thiab txias, kev poob ntawm lub hauv paus, thiab kev siv nyiaj tsim nyog. Cov yam ntxwv ntawm nanocrystalline thiab amorphous ribbons ua rau lawv yog cov khoom tseem ceeb hauv cov khoom siv hluav taws xob, cov tshuab hluav taws xob rov ua dua tshiab, tsheb fais fab, thiab ntau yam thev naus laus zis niaj hnub.
Xaus lus, nanocrystalline ribbon thiab amorphous ribbon muaj cov txiaj ntsig sib txawv hauv kev siv hauv kev lag luam sib txawv. Nanocrystalline ribbons muab kev txhim kho magnetic permeability thiab thermal stability, ua rau lawv zoo tagnrho rau kev siv hauv transformers thiab magnetic cores. Amorphous ribbons, ntawm qhov tod tes, muaj cov khoom zoo heev magnetic mos thiab qis core poob, ua rau lawv haum rau kev siv hauv high-energy transformers thiab EMI shields. Kev nkag siab txog qhov sib txawv ntawm nanocrystalline thiab amorphous ribbons ua rau cov engineers thiab cov chaw tsim khoom xaiv cov khoom siv tsim nyog tshaj plaws rau lawv cov kev xav tau tshwj xeeb, kom ntseeg tau tias muaj kev ua tau zoo tshaj plaws thiab ua haujlwm tau zoo hauv lawv cov khoom.
