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 seb puas muaj ntau tus ncej magnetizedSmCo hlau nplaumyog ua tau los tsis, piv txwv li, qhov sib txawv ntawm cov hlau nplaum ncej, hlau nplaum loj, magnetizing fixture, hlau nplaum zog, 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:
| Yam ntxwv | Reversible Temperature Coefficient 20-150ºC, α (Br) | Reversible Temperature Coefficient 20-150ºC, β (Hcj) | Coefficient ntawm Thermal Expansion | Thermal conductivity | Tshwj xeeb kub | Curie Kub | Flexural zog | Qhov ntom | Hardness, Vickers | Hluav taws xob Resistivity |
| Chav tsev | % / ºC | % / ºC | ΔL/L per ºCx10-6 | kcal / mhrºC | cal/gºC | ºC | Mpa | g/cm3 | Hv | μΩ • cm |
