Nrog rau cov thev naus laus zis thiab cov chaw tsim khoom, kev tswj hwm nruj, tsim nyog tus nqi, lub tuam txhab tshwj xeeb thiab kev sib koom tes nrog cov zeem muag, peb tau mob siab rau muab qhov zoo tshaj plaws tsim nyog rau peb cov neeg siv khoom rau Cov Tuam Txhab Tuam Txhab Tuam Txhab Suav Muab Sm2co17 Magnet rau Muag nrog Tus nqi sib tw, Los ntawm 10 xyoo kev rau siab, peb nyiam cov neeg yuav khoom los ntawm kev sib tw tus nqi thiab cov neeg muab kev pabcuam zoo heev. Ntxiv mus, nws tiag tiag yog peb cov neeg ncaj ncees thiab lub siab dawb paug, uas txhawb peb feem ntau yog cov neeg siv khoom los pib nrog kev xaiv.
Nrog rau cov thev naus laus zis thiab cov chaw tsim khoom, kev tswj hwm nruj, tsim nyog tus nqi, lub tuam txhab tshwj xeeb thiab kev sib koom tes nrog cov kev cia siab, peb tau mob siab rau muab qhov zoo tshaj plaws tsim nyog rau peb cov neeg siv khoom.Tuam Tshoj SmCo Magnet, SmCo, Raws li lub Hoobkas muaj kev paub dhau los peb kuj lees txais kev txiav txim siab thiab ua kom zoo ib yam li koj daim duab lossis cov qauv kev qhia tshwj xeeb thiab cov neeg siv khoom tsim khoom. Lub hom phiaj tseem ceeb ntawm lub tuam txhab yog ua lub cim xeeb txaus siab rau txhua tus neeg siv khoom, thiab tsim kom muaj kev sib raug zoo ntawm kev lag luam ntev-yeej. Yog xav paub ntxiv, koj yuav tsum tiv tauj peb. Thiab Nws yog peb qhov zoo siab heev yog tias koj nyiam tuaj ntsib tus kheej hauv peb lub hoobkas.
Samarium hlau nplaum lub tog raj kheej los yogSmCoLub tog raj kheej hlau nplaum piav qhia txog cov hlau nplaum puag ncig nrog qhov siab loj dua txoj kab uas hla. Feem ntau ntawm lub tog raj kheej SmCo hlau nplaum yog axially magnetized, thiab qee qhov yog magnetized diametrically.
Rau axially magnetized SmCo lub tog raj kheej hlau nplaum, qee zaum lawv yuav tsum tau ntau tus ncej magnetized los ntawm qhov ntev rau qee qhov kev siv tshwj xeeb. Muaj ob peb yam los txiav txim siab seb tus ncej hlau nplaum SmCo hlau nplaum yog qhov ua tau los yog tsis, piv txwv li, qhov sib txawv ntawm cov hlau nplaum, cov hlau nplaum loj, cov hlau nplaum sib nqus, cov khoom hlau nplaum, thiab lwm yam. NdFeB hlau nplaum. Yog tias SmCo hlau nplaum loj dhau lawm, cov hlau nplaum thiab cov hlau nplaum sib nqus tsis tuaj yeem tsim kom muaj cov hlau nplaum txaus los ua kom cov hlau nplaum SmCo kom saturation. Nquag cov tuab ntawm SmCo hlau nplaum yuav tsum qis dua 5 hli, thiab qee zaum Hcj yuav tsum tau tswj los yog tsis pub tshaj 15kOe. Ua ntej kev tsim khoom loj, cov qauv ntawm ntau tus ncej hlau nplaum yuav tsum tau lees paub los ntawm cov neeg siv khoom 'kev sim ua kom tau raws li daim ntawv thov.
Qee zaum, lub tog raj kheej SmCo hlau nplaum yuav xav tau plating. Tsis zoo li sintered Neodymium hlau nplaum yooj yim rau oxidize, Samarium Cobalt hlau nplaum yog qhov zoo ntawm corrosion kuj vim nws cov khoom tshwj xeeb tsis muaj Fe lossis tsuas yog nyob ib ncig ntawm 15% hlau. Yog li ntawd nyob rau hauv feem ntau daim ntaub ntawv, txheej tsis xav tau rau SmCo hlau nplaum los tiv thaiv corrosion. Txawm li cas los xij, hauv qee daim ntawv thov, SmCo hlau nplaum yuav tsum tau coated nrog ci los yog zoo nkauj kub los yog Nickel kom ncav cuag ib tug zoo meej tsos.
Thaum cov neeg siv khoom txiav txim siab cov khoom siv hlau nplaum twg yog qhov tsim nyog rau lawv daim ntawv thov, lawv kuj saib xyuas cov khoom siv lub cev. Hauv qab no yog lub cev muaj zog rau SmCo hlau nplaum:
