Huina oNā Mākēneki Paʻa Samarium Cobalt
ʻO ka Samarium cobalt permanent magnet he mea hoʻokalakupua honua, ka mea nui i haku ʻia me metala samarium (Sm), metala cobalt (Co), keleawe (Cu), hao (Fe), zirconium (Zr) a me nā mea ʻē aʻe, mai ka hale i māhele ʻia i 1 :5 ʻano a me 2:17 ʻano ʻelua, no ka hanauna mua a me ka lua o ka lua o nā mea hoʻonaninani mau loa.Loaʻa i ka Samarium cobalt mau mea hoʻokele waiwai maikaʻi loa (kiʻekiʻe remanence, kiʻekiʻe coercivity a me kiʻekiʻe magnetic ikehu huahana), haʻahaʻa haʻahaʻa wela coefficient, kiʻekiʻe lawelawe wela a me ka ikaika corrosion kū'ē, 'o ia ka maikaʻi loa wela kūpaʻa paʻa mau mea magnet, hoʻohana nui i ka microwave nā manaʻo, electron. nā mea uila, nā kaʻa mana kiʻekiʻe/kiʻekiʻe, nā mea ʻike, nā ʻāpana magnetic a me nā ʻoihana ʻē aʻe.
Hana o 2:17 samarium-cobalt magnet
ʻO kekahi o nā magnet samarium-cobalt kaulana loa ʻo ia ka 2:17 samarium-cobalt magnet, kahi ʻano o nā mea magnet i ʻike ʻia no ko lākou mau waiwai magnetic kiʻekiʻe, e hana ana iā lākou i koho mua no nā noi e koi ana i ka ikaika magnetic kiʻekiʻe a me ke kūpaʻa.
Mai nā hiʻohiʻona hana, 2:17 samarium-cobalt mau mākēneki mau hiki ke hoʻokaʻawale ʻia i nā moʻo hana kiʻekiʻe, nā moʻo paʻa kiʻekiʻe (koehana haʻahaʻa haʻahaʻa) a me nā moʻo kūpaʻa kiʻekiʻe.ʻO ka hui ʻokoʻa o ke kiʻekiʻe o ka ikehu magnetic, ke kūpaʻa o ka mahana a me ke kūpaʻa ʻana i ka corrosion e hana i nā magnet mau loa o ka samarium-cobalt i kūpono no nā ʻano noi like ʻole, me nā mīkini uila, nā mea ʻike, nā hoʻohui magnetic a me nā mea hoʻokaʻawale magnetic.
ʻO ka nui o nā huahana ikehu magnetic o kēlā me kēia papa ma waena o 20-35MGOe, a ʻo ka mahana hana kiʻekiʻe he 500 ℃.Loaʻa i nā magnet mau loa ʻo Samarium-cobalt i kahi hui like ʻole o ka coefficient haʻahaʻa haʻahaʻa a me ke kūpaʻa corrosion maikaʻi, ke kiʻekiʻe o ka ikehu magnetic, ka paʻa ʻana o ka mahana a me ke kūpaʻa ʻana o ka corrosion, e hana ana i nā magnet mau loa o ka samarium-cobalt i kūpono no ka nui o nā noi, e like me nā motika uila, nā ʻike, magnetic. nā mea hoʻohui a me nā mea hoʻokaʻawale magnetic.
ʻO nā waiwai magnetic o ka samarium cobalt magnets i nā wela kiʻekiʻe ma mua o ka Ndfeb magnets no laila ua hoʻohana nui ʻia lākou i ka aerospace, nā kahua kaua, nā kaʻa wela wela, nā ʻenekona automotive, nā ʻano mea hoʻokele magnetic, nā paila magnetic a me nā polokalamu microwave.2:17 ʻanonā mākēneki kobalt samarium He palupalu loa, ʻaʻole maʻalahi ke hoʻololi i nā ʻano paʻakikī a i ʻole nā pepa lahilahi a me nā apo ʻāpana lahilahi, ʻoi aku ka maʻalahi o ka hana ʻana i nā kihi liʻiliʻi i ke kaʻina hana, ʻoiai ʻaʻole ia e pili i nā waiwai magnetic a i ʻole nā hana. hiki ke manaʻo ʻia he huahana kūpono.
I ka hōʻuluʻulu manaʻo, ʻo samarium cobalt mau mākēneki mau loa, ʻoi aku ka nui o ka moʻo kiʻekiʻeSm2Co17 mau mākēneki, mahalo nui ʻia no kā lākou mau waiwai magnetic maikaʻi a paʻa.ʻO ko lākou hiki ke kū i nā wela kiʻekiʻe a me nā wahi paʻakikī e lilo lākou i koho mua no ka koi ʻana i nā noi ma nā ʻoihana.Ke hoʻomau nei ka ʻenehana i ka holomua, ke manaʻo nei e ulu ka noi no nā magnet permanent samarium-cobalt, e hoʻopaʻa hou i ko lākou kūlana ma ke ʻano he mea nui no nā noi ʻoihana a me nā ʻoihana.
