Lub magnetization kev taw qhia ntawm cov hlau nplaum yog txiav txim siab thaum lub sij hawm fabrication txheej txheem. Cov kev taw qhia magnetization ntawm cov khoom tiav tsis tuaj yeem hloov pauv. Thov nco ntsoov qhia qhov xav tau magnetization kev taw qhia ntawm cov khoom.
Tam sim no cov pa magnetization kev taw qhia yog qhia nyob rau hauv daim duab hauv qab no:
Magnetization kev taw qhia yog thawj kauj ruam rau cov khoom siv hlau nplaum ruaj khov xws li lub ntiaj teb tsis tshua muaj hlau boron thiab samarium cobalt hlau nplaum kom tau txais cov hlau nplaum. Nws sawv cev rau sab qaum teb thiab sab qab teb ntawm cov hlau nplaum lossis cov khoom sib nqus. Cov khoom sib nqus ntawm cov khoom siv hlau nplaum ruaj khov yog tsim los ntawm lawv cov qauv siv lead ua yooj yim magnetizable. Nrog rau qhov kev tsim kho no, cov hlau nplaum tuaj yeem tau txais cov khoom sib nqus siab heev nyob rau hauv qhov kev txiav txim ntawm lub zog sab nraud magnetic teb, thiab nws cov khoom sib nqus yuav tsis ploj tom qab sab nraud magnetic teb ploj.
Puas tuaj yeem hloov pauv cov kev taw qhia ntawm cov hlau nplaum?
Los ntawm qhov kev xav ntawm kev taw qhia magnetization, cov khoom sib nqus tau muab faib ua ob pawg: cov hlau nplaum isotropic thiab anisotropic hlau nplaum. Raws li lub npe qhia:
Cov hlau nplaum Isotropic muaj cov khoom sib nqus zoo ib yam hauv txhua qhov kev taw qhia thiab nyiam ua ke arbitrarily.
Anisotropic cov khoom sib nqus ruaj khov muaj ntau yam khoom sib nqus hauv cov lus qhia sib txawv, thiab cov kev taw qhia uas lawv tuaj yeem tau txais cov khoom sib nqus zoo tshaj plaws / muaj zog tshaj plaws yog hu ua kev taw qhia ntawm cov khoom sib nqus mus tas li.
Kev taw qhia thev naus laus zis yog txheej txheem tsim nyog los tsim cov khoom siv hlau nplaum anisotropic ruaj khov. Cov hlau nplaum tshiab yog anisotropic. Cov kev taw qhia sib nqus ntawm cov hmoov yog ib qho ntawm cov thev naus laus zis tseem ceeb rau kev tsim cov hlau nplaum zoo NdFeB. Sintered NdFeB feem ntau yog nias los ntawm magnetic teb orientation, yog li cov kev taw qhia kev taw qhia yuav tsum tau txiav txim siab ua ntej ntau lawm, uas yog qhov nyiam magnetization kev taw qhia. Thaum cov hlau nplaum neodymium raug tsim, nws tsis tuaj yeem hloov cov kev taw qhia ntawm magnetization. Yog tias pom tias qhov kev taw qhia magnetization tsis raug, cov hlau nplaum yuav tsum tau kho dua tshiab.
Txheej thiab Plating
Vim qhov tsis zoo corrosion kuj ntawm NdFeB hlau nplaum, electroplating feem ntau yuav tsum tau tiv thaiv corrosion. Tom qab ntawd lo lus nug los, kuv yuav tsum tau phaj cov hlau nplaum rau dab tsi? Dab tsi yog qhov zoo tshaj plaws plating? Hais txog qhov zoo tshaj plaws ntawm NdFeB txheej rau saum npoo, ua ntej ntawm tag nrho cov, peb yuav tsum paub tias NdFeB tuaj yeem plated?
Dab tsi yog cov txheej txheem ntawm NdFeB hlau nplaum?
NdFeB muaj zog hlau nplaum txheej feem ntau yog npib tsib xee, zinc, epoxy resin thiab lwm yam. Nyob ntawm cov electroplating, cov xim ntawm cov hlau nplaum saum npoo kuj yuav txawv, thiab lub sijhawm cia kuj yuav txawv rau lub sijhawm ntev.
Cov teebmeem ntawm NI, ZN, epoxy resin, thiab PARYLENE-C coatings ntawm cov khoom sib nqus ntawm NdFeB hlau nplaum hauv peb txoj kev daws teeb meem tau kawm los ntawm kev sib piv. Cov txiaj ntsig tau pom tias: nyob rau hauv cov kua qaub, alkali, thiab ntsev ib puag ncig, cov khoom siv polymer txheej tiv thaiv cov hlau nplaum yog qhov zoo tshaj plaws, cov epoxy resin kuj tsis zoo, NI txheej yog thib ob, thiab ZN txheej kuj tsis zoo:
Zinc: Qhov saum npoo zoo li silvery dawb, tuaj yeem siv rau 12-48 teev cov tshuaj ntsev ntsev, tuaj yeem siv rau qee cov kua nplaum sib txuas, (xws li AB kua nplaum) tuaj yeem khaws cia rau ob mus rau tsib xyoos yog tias nws yog electroplated.
Nickel: zoo li cov hlau tsis muaj steel, qhov saum npoo yog qhov nyuaj rau oxidized nyob rau hauv cov huab cua, thiab cov tsos zoo, gloss yog zoo, thiab electroplating tuaj yeem xeem cov ntsev tsuag rau 12-72 teev. Nws qhov tsis zoo yog tias nws tsis tuaj yeem siv rau kev sib txuas nrog qee cov kua nplaum, uas yuav ua rau cov txheej txheem poob. Ua kom oxidation ceev, tam sim no cov txheej txheem nickel-tooj liab-nickel electroplating feem ntau yog siv hauv khw rau 120-200 xuab moos ntsev tsuag.

Ntim
Ntim cov ntsiab lus: ntim cov khoom ntim nrog cov hlau nplaum, cov thawv ua npuas dej, cov thawv dawb thiab cov ntawv hlau, uas tuaj yeem ua lub luag haujlwm tiv thaiv cov hlau nplaum thaum thauj.
Tus me nyuam cov ntsiab lus: Hauv 7-30 hnub tom qab kev txiav txim pom zoo.
