SmCo Magnet 1:5 a me 2:17

ʻO ka wehewehe pōkole:

ʻO SmCo magnet kahi ʻano magnet honua laha ʻole, ʻo ia ka magnet i hana ʻia me ka samarium, cobalt a me nā mea metala ʻē aʻe.Hoʻokumu ʻia i ka makahiki 1970, ʻo SmCo magnet ka lua o ka ikaika, ʻelua wale nō i ka NdFeB magnet, me ka huahana ikehu kiʻekiʻe (BHmax mai 9MGOe a 31 MGOe) a me ka coercivity kiʻekiʻe.ʻElua mau lākiō haku mele SmCo, ʻo ia ʻo SmCo5 a me Sm2Co17.ʻO ka maʻiʻo o ka amarium alloy ma kahi o 25% -36% ma ke kaumaha a he mea pono loa ia i nā hana wela kiʻekiʻe a hiki ke hoʻohana ʻia i nā noi wela kiʻekiʻe.ʻO ka mahana Curie o SmCo magnet he 600-710 ℃, a ʻo ka mahana hana he 250-550 ℃.

Ma waho aʻe, he mau hiʻohiʻona ʻē aʻe nā SmCo magnets:
ʻO ka hana hilinaʻi: Paʻa loa nā magnet SmCo i ka demagnetization e hilinaʻi iā lākou i nā wahi he nui.
ʻO ke kūpaʻa ʻino a me ka pale ʻana: Ma muli o ka haʻahaʻa haʻahaʻa o ka hao i loko o ka mea i hui pū ʻia, loaʻa i nā magnet SmCo ke kūpaʻa maikaʻi loa.ʻAʻole like me NdFeB, ʻaʻole pono nā magnet SmCo i ka electroplating.
Paʻa wela: Hiki iā SmCo ke hoʻomau i kona ikaika magnetic ma nā wela kiʻekiʻe (249-300 ℃) a me nā wela haʻahaʻa loa (-232 ℃).
ʻO nā mea palupalu: I ka wā o ka sintering, hiki ke palupalu ka mea, no ka palupalu a maʻalahi hoʻi e haki, aia nā palena o ka hana, ʻaʻole hiki ke hana ʻia nā ʻano hana kuʻuna.Eia nō naʻe, hiki ke hoʻoneʻe ʻia, akā inā hoʻohana ʻia ka nui o ka coolant.ʻO ia no ka mea hiki i ka mea hoʻomaʻamaʻa ke hōʻemi i ka pilikia o ke ahi mai ka pohā wela a me ka lepo wili oxidized.

Nā noi:
1. Nā motika PM kiʻekiʻe.Hoʻohana maʻamau nā motika PM maʻamau i nā magnet ferrite a i ʻole NdFeB magnet.Akā ma nā wahi i ʻoi aku ka mahana ma mua o 200 ℃ a i ʻole ka nui o ka stall torque, ʻo nā kaʻa SmCo PM wale nō ka mākaukau.
2. Electroacoustic nā mea hana i loko o nā ʻōnaehana leo leo kiʻekiʻe.
3. Pūnaehana mea kani hilinaʻi loa.Nui nā mea kani i hoʻohana ʻia i ka aerospace, aviation, medical and other fields e pono e hoʻohana iā SmCo permanent magnets e hōʻoia i ka hilinaʻi kiʻekiʻe a me ka palekana kūpono.
4. I loko o ka radar koʻikoʻi a me nā ʻōnaehana kamaʻilio, ua hoʻohana ʻia ka heluna nui o nā paipu nalu hele, magnetrons, nā paipu alualu, nā paipu hawewe alualu, nā gyrotrons a me nā mea uila uila ʻē aʻe e hoʻohana ʻia, a hana nā SmCo magnet i nā kukuna electron ma ka neʻe ʻana ma ke ala i kuhikuhi ʻia.
5. SmCo magnetic extractors i loko o nā luawai hohonu ma lalo o 3000 mika, a me SmCo magnetic drive (pump) ma ke kiʻekiʻe wela kaiapuni o 200 ℃.
6. ʻO ke poʻo hoʻoheheʻe mākēneki, ka mea hoʻokaʻawale hoʻokaʻawale, ka halihali magnetic, NMR, etc.
