Nā Samarium Cobalt Magnet



Description

Ma ke ʻāpana o ka pūʻulu honua laha ʻole o nā mākēneki kū mau, hāʻule nā ​​mākēneki samarium cobalt (SmCo) i ʻelua mau ʻohana mea waiwai. Hoʻopili lākou i ka honua Sm1Co5 a me Sm2Co17 kakaikahi a kapa ʻia ʻo 1: 5 a me 2:17 mau mea. ʻEkolu mau kaʻina hana ʻokoʻa: sinter SmCo magnet, bonded SmCo magnet, a me injection injection SmCo magnet. SmCo Mākēneki mea kiʻekiʻe hana, haʻahaʻa wela kaʻi lau waiwai paʻa o ka samarium a me ka cobalt a me nā mea kamaha-honua hehee wale. ʻO kāna keu ʻoi aku ka nui o ka mahana-300 degree centigrade. Pono e uhi ʻia no ka mea paʻakikī e holoi ʻia a oxidized. Hoʻohana ākea ʻo SmCo magnet i ka moto, kiaʻi, transducers, mea kani, mea ʻike hoʻonohonoho hoʻonohonoho, mīkini hana wāwahie, radar, a pēlā aku.
 
Mālama ʻo Samarium Cobalt i kāna waiwai maʻamau i nā mahana kiʻekiʻena ʻoi aku ma mua o neodymium, ʻoiai ʻoi aku ka liʻiliʻi o kāna strengh maximum. ʻO ke kumukūʻai o nā mea SmCo ka mea pipiʻi loa, no laila ʻo SmCo ke paipai ʻia wale ke hana ʻia kahi ʻano wela kiʻekiʻe he mea hopohopo.
 
1.SmCo paʻa mau ka Mākēneki he kiʻekiʻe ʻume mākenēki huahana huahana a kiʻekiʻe coercive ikaika. ʻOi aku ka maikaʻi o kāna mau waiwai ma mua o Alnico, ferrite paʻa paʻa. Kona max. Aia ka huahana ikehu a hiki i 239kJ / m3 (30MGOe), ʻo ia ʻekolu mau manawa o ka AlNiCo8 paʻa mau, ʻewalu mau manawa o ka ferrite paʻa mau (Y40). No laila, ʻo ka mea paʻa mau i hana ʻia mai SmCo mea liʻiliʻi, māmā a paʻa i ka waiwai. Hoʻohana ākea ia i ka electro acoustic & telecommunication aparatus, uila uila, ana mika, peg-luna uila uaki, hawewe mea paahana, ʻume mākenēkiʻano papa hana, mīkiniʻimi a me nā kūpaʻa a hōʻeuʻeu nā mākē ala.
 
2. ʻO ka curie temp. o ka SmCo paʻa Mākēneki mea kiʻekiʻe a me kona temp. ʻO Coeff. haʻahaʻa. No laila kūpono ia no ka hoʻohana ma 300, temp kiʻekiʻe.
 
3.SmCo paʻa mau ka Mākēneki lohe a hulu hulu. ʻO kona ikaika paʻa, haʻahaʻa ikaika a haʻahaʻa ka ikaika. No laila ʻaʻole kūpono ia no ke kuhi.
 
4.ʻO ka mea hana nui o SmCo magnet magnet ʻo ka cobalt metala (CoY99.95%). No laila he kiʻekiʻe kona kumu kūʻai.


'Apono kūpono:
Nā ʻano o Samarium Cobalt Mākēneki

* ʻO nā waiwai magnet kiʻekiʻe loa me ka paʻa maikaʻi.
* Ke kūʻē ʻoi aku i ka mahana kiʻekiʻe, ʻo Curie ka mahana o ka hapa nui ma luna o 800 ?? * Maikaʻi kūpaʻa kūpaʻa hiki, ʻaʻohe pale e pono ai no ka pale o luna.
