Samarium Cobalt Magnet yog dab tsi?

Dab tsi yog samarium cobalt hlau nplaum?

Samarium cobalt hlau nplaum, tseem hu ua samarium cobalt ruaj khov hlau nplaum, yog ib hom hlau nplaum ruaj khov ua los ntawm samarium thiab cobalt. Zoo li NdFeB, nws kuj yog cov hlau nplaum hauv ntiaj teb tsawg. Tam sim no, nws tsuas yog muaj SmCo5 thiab Sm2Co17.

Txawm hais tias lub zog sib nqus ntawm SmCo tsis muaj zog li ntawm NdFeB, SmCo muaj ob qhov zoo: qhov kub thiab txias ntau dua thiab zoo dua corrosion kuj. Yog li ntawd, lawv muab tus nqi zoo tshaj plaws thaum sib piv kev ua tau zoo thiab qhov loj me hauv qhov kub thiab txias ib puag ncig lossis kev siv.

 

Keeb kwm ntawm SmCo hlau nplaum:

Samarium cobalt hlau nplaum tau qhia hauv xyoo 1970 yog thawj pawg ntawm cov hlau nplaum uas tsis tshua muaj hauv ntiaj teb. Lawv lub community launch yog revolutionary thiab tripled lub siab tshaj plaws zog khoom ntawm lwm yam hlau nplaum thaum lub sij hawm. Ua ntej kev taw qhia ntawm SmCo hlau nplaum, tus qauv ntawm cov hlau nplaum yog alnico alloy hlau nplaum. Txog thaum nce nqi ntau lawm coj cov engineers mus nrhiav cov kev xaiv pheej yig dua, cov hlau nplaum neodymium tau tsim thiab tam sim no yog cov hlau nplaum muaj zog tshaj plaws hauv ntiaj teb.

 

Qhov zoo ntawm SmCo mus tas li hlau nplaum:

SmCo hlau nplaum tsis muaj zog li super neodymium hlau nplaum, tab sis lawv muaj qee qhov zoo. SmCo hlau nplaum muaj qhov dav ntawm kev khiav hauj lwm kub, superior kub coefficient thiab ntau dua corrosion kuj. Nws yog qhov zoo tshaj qhov tshwj xeeb kub neodymium hlau nplaum ntawm 150 degree.

SmCo hlau nplaum tsis tsuas yog ua tau zoo ntawm qhov kub thiab txias, tab sis kuj tswj lawv cov hlau nplaum txawm tias qhov kub thiab txias qis dua xoom ({0}} degree), yog li lawv nrov heev hauv cov ntawv thov kub.

Vim tias feem ntau qib ntawm samarium cobalt muaj cov hlau me me, lawv muaj kev tiv thaiv corrosion zoo heev.

 

Disadvantages ntawm SmCo hlau nplaum:

Ntawm qhov tod tes, vim yog tus nqi ntawm kev tsim cov cobalt, samarium cobalt hlau nplaum yuav kim dua neodymium hlau nplaum (cobalt ua lag luam tus nqi rhiab). Zoo li lwm cov hlau nplaum hauv ntiaj teb tsis tshua muaj, lawv kuj yog cov nkig heev, yog li lawv tsim nyog rau cov ntawv thov uas tsis tas yuav cuam tshuam ncaj qha.

 

Kev siv ntawm SmCo hlau nplaum:

SmCo hlau nplaum, vim lawv cov khoom, feem ntau yog siv rau hauv cov ntawv thov uas xav tau kev ua haujlwm siab, xws li cov tshuab hluav taws xob, twj tso kua mis txuas, sensors, motors, marine applications, nrog rau tsheb, kev sib tw, aerospace, tub rog thiab khoom noj khoom haus thiab kev lag luam.
