Cov txheej txheem no ua rau muaj cov qauv atomic uas tsis muaj kev txiav txim ntev, muab cov khoom siv nws cov yam ntxwv tshwj xeeb.
Nanocrystalline Core yog dab tsi?
Ntawm qhov tod tes, lub nanocrystalline core yog ib hom khoom siv hlau nplaum uas muaj cov nanometer-sized crystalline grains embedded rau hauv ib lub amorphous matrix. Cov qauv dual-phase no ua ke cov txiaj ntsig ntawm ob qho tib si crystalline thiab amorphous cov ntaub ntawv, ua rau muaj cov khoom sib nqus zoo heev thiab cov dej ntws ceev ceev.
Cov tub ntxhais nanocrystallinefeem ntau yog ua los ntawm kev sib xyaw ua ke ntawm hlau, nickel, thiab cobalt, nrog rau kev ntxiv me me ntawm lwm yam khoom xws li tooj liab thiab molybdenum. Cov qauv nanocrystalline muab cov permeability magnetic siab, coercivity qis, thiab kev ruaj khov thermal zoo dua, ua rau nws tsim nyog rau cov ntawv thov muaj zog thiab cov transformers siab.
Qhov sib txawv ntawm Amorphous Core thiab Nanocrystalline Core
Qhov sib txawv tseem ceeb ntawm cov amorphous cores thiab nanocrystalline cores yog nyob rau hauv lawv cov qauv atomic thiab cov khoom sib nqus. Thaum cov amorphous cores muaj cov qauv tsis yog crystalline kiag li, cov nanocrystalline cores qhia txog cov qauv dual-phase uas muaj cov nanometer-sized crystalline grains hauv ib lub amorphous matrix.
Nyob rau hauv cov nqe lus ntawm cov khoom sib nqus,cov tub ntxhais amorphouspaub txog lawv qhov kev poob qis ntawm cov tub ntxhais thiab kev nkag tau zoo, ua rau lawv zoo tagnrho rau cov ntawv thov uas kev siv hluav taws xob zoo tshaj plaws. Ntawm qhov tod tes, cov tub ntxhais nanocrystalline muab cov dej ntws ntau dua thiab kev ruaj khov thermal zoo dua, ua rau lawv haum rau cov ntawv thov muaj zog thiab zaus siab.
Lwm qhov txawv tseem ceeb yog cov txheej txheem tsim khoom. Cov amorphous cores yog tsim los ntawm kev khov sai, uas cuam tshuam nrog kev quenching cov hlau molten ntawm qhov nrawm siab kom tiv thaiv kev tsim crystalline. Qhov sib piv, nanocrystalline cores feem ntau yog tsim los ntawm kev annealing thiab tswj crystallization ntawm amorphous ribbons, ua rau muaj kev tsim cov nanometer-sized crystalline nplej hauv cov khoom siv.
Cov Kev Xav Txog Daim Ntawv Thov
Thaum xaiv cov amorphous cores thiab nanocrystalline cores rau ib daim ntawv thov tshwj xeeb, ntau yam yuav tsum tau xav txog. Rau cov ntawv thov uas muab qhov tseem ceeb rau kev poob hluav taws xob tsawg thiab kev ua haujlwm siab, xws li hauv cov transformers faib hluav taws xob thiab cov inductors siab zaus, amorphous cores feem ntau yog qhov kev xaiv zoo tshaj plaws. Lawv qhov kev poob qis core thiab kev nkag tau zoo ua rau lawv zoo rau cov ntawv thov no, pab txhawb rau kev txuag hluav taws xob tag nrho thiab kev ua haujlwm zoo dua.
Ntawm qhov tod tes, rau cov ntawv thov uas xav tau qhov ceev ntawm cov khoom siv hluav taws xob ntau, kev ruaj khov thermal zoo dua, thiab kev muaj peev xwm tswj hwm lub zog siab, cov nanocrystalline cores zoo dua. Cov yam ntxwv no ua rau cov nanocrystalline cores zoo tagnrho rau cov transformers muaj zog siab, cov ntawv thov inverter, thiab cov khoom siv fais fab zaus siab, qhov twg lub peev xwm los tswj cov khoom siv hluav taws xob sib nqus siab thiab tswj kev ruaj khov nyob rau hauv ntau yam kev ua haujlwm yog qhov tseem ceeb.
Xaus lus, ob qho tib si amorphous cores thiab nanocrystalline cores muaj cov txiaj ntsig tshwj xeeb thiab raug tsim los rau cov kev xav tau tshwj xeeb.
