Kufotokozera Kwachidule:

SmCo maginito ndi mtundu wa maginito osowa padziko lapansi, omwe ndi maginito opangidwa ndi samarium, cobalt ndi zitsulo zina zapadziko lapansi.Kupangidwa mu 1970, SmCo maginito ndi chachiwiri amphamvu, wachiwiri kwa NdFeB maginito, ndi mkulu pazipita mankhwala mphamvu (BHmax kuyambira 9MGOe 31 MGOe) ndi high coercivity.Pali mitundu iwiri ya maginito a SmCo, omwe ndi SmCo5 ndi Sm2Co17.Zomwe zili mu aloyi ya amarium ndi pafupifupi 25% -36% kulemera kwake ndipo ndizothandiza kwambiri pochita ntchito zotentha kwambiri ndipo zingagwiritsidwe ntchito pa kutentha kwakukulu.The Curie kutentha kwa SmCo maginito ndi 600-710 ℃, ndi kutentha ntchito ndi 250-550 ℃.

Kupatula apo, maginito a SmCo ali ndi zina:
Kuchita kodalirika: Maginito a SmCo ndi osagwirizana kwambiri ndi demagnetization kuwapangitsa kukhala odalirika m'malo ambiri.
Kukana kwa dzimbiri ndi makutidwe ndi okosijeni: Chifukwa chokhala ndi chitsulo chochepa muzinthu zophatikizika, maginito a SmCo ali ndi kukana kwambiri kwa dzimbiri.Mosiyana ndi NdFeB, maginito a SmCo safuna electroplating.
Kutentha bata: SmCo akhoza kusunga mphamvu yake maginito pa kutentha (249-300 ℃) ndi kutentha otsika kwambiri (-232 ℃).
Zida za Brittle: Mukakhala mu sintering, zinthuzo zikhoza kukhala zowonongeka, chifukwa cha brittle komanso zosavuta kusweka , kukonza kumakhala ndi malire, omwe njira zoyendetsera ntchito sizingagwire ntchito.Komabe, ikhoza kuphwanyidwa, koma pokhapokha ngati zoziziritsa zambiri zimagwiritsidwa ntchito.Izi ndichifukwa choti choziziritsa kukhosi chimatha kuchepetsa ngozi ya moto chifukwa cha kung'ambika kwamafuta komanso fumbi logaya okosijeni.

Mapulogalamu:
1. Ma motors apamwamba a PM.Ma motors a PM nthawi zambiri amagwiritsa ntchito maginito a ferrite kapena maginito a NdFeB.Koma m'malo omwe kutentha kumapitilira 200 ℃ kapena torque ya khola ndi yayikulu, ma motors a SmCo PM okha ndi omwe ali oyenerera.
2. Zipangizo za Electroacoustic m'makina okweza mawu apamwamba.
3. Dongosolo la chida chodalirika kwambiri.Zida zambiri zomwe zimagwiritsidwa ntchito muzamlengalenga, ndege, zamankhwala ndi zina ziyenera kugwiritsa ntchito maginito okhazikika a SmCo kuonetsetsa kudalirika kwakukulu komanso chitetezo changwiro.
4. M'machitidwe ofunikira kwambiri a radar ndi kulumikizana, machubu ambiri oyendayenda, maginito, machubu othamangitsa, machubu othamangitsa, ma gyrotrons ndi zida zina zamagetsi zamagetsi zimagwiritsidwa ntchito, ndipo maginito a SmCo amapanga matabwa a ma elekitironi motsatira njira yomwe adalangizidwa.
5. SmCo maginito extractors mu zitsime zakuya pansi mamita 3000, ndi SmCo maginito pagalimoto (pampu) mu kutentha chilengedwe 200 ℃.
6. Maginito suction mutu, maginito olekanitsa, maginito kubala, NMR, etc.
