Nā Mākēneki Samarium Cobalt (SmCo).
ʻO Samarium Cobalt Magnets (SmCo Magnets) he ʻano o nā mea kiʻekiʻe mau loa. Hana ʻia lākou me ka metallic samarium, cobalt, a me nā metala ʻē aʻe, e hoʻolilo iā lākou i mea waiwai nui loa e hana ai. ʻO ke kaʻina hana e pili ana i ka hoʻoheheʻe ʻana, ka wili ʻana, ka paʻi ʻana, a me ka sintering, ka hopena i nā waiwai like ʻole a me nā māka o nā magnet. ʻO kahi pōmaikaʻi nui o nā magnet SmCo ʻo ko lākou kūpaʻa kiʻekiʻe i ka corrosion, a me ko lākou hiki ke kū i nā wela kiʻekiʻe, hiki i 350 °C, a i kekahi manawa ʻo 500 °C. Hoʻokaʻawale kēia kūpaʻa wela iā lākou mai nā magnet mau ʻē aʻe me ka haʻahaʻa haʻahaʻa i nā wela wela, e hāʻawi ana i nā magnet SmCo i kahi lihi koʻikoʻi.
E like me nā kikoʻī o ka mea kūʻai aku, e hana ʻia nā roughcasts o SmCo Magnets e loaʻa i nā ʻano a me nā nui i makemake ʻia. Inā ʻaʻole i kuhikuhi ʻia e ka mea kūʻai aku, e hoʻomāke ʻia nā huahana hope loa. Loaʻa i nā mea magnetic, e like me SmCo Magnets, ka mea hoʻokalakupua a hōʻike i nā hopena magnetic like ʻole. Hiki iā lākou ke hana i nā māla magnetic no nā noi e like me nā kaʻa, nā mīkini magnetic, nā mea ʻike, a me nā polokalamu microwave, a me nā mea ʻē aʻe. Ma ka hana ʻana ma ke ʻano he ala no ka hoʻololi ʻana a me ka hoʻololi ʻana i ka ikehu magnetic i ka ikehu mechanical a me ka ikehu uila, hoʻomaʻamaʻa nā mea magnetic i ka mana a loaʻa i nā hopena i makemake ʻia.
SmCo Magnets ua like i ka ikaika iNā Mākēneki Neodymiumakā, ʻoi aku ka kiʻekiʻe o ka wela a me ka coercivity. ʻO SmCo Magnes ka mea i koho ʻia no nā noi kaʻa ʻoi loa ma muli o ko lākou kūpaʻa ikaika ʻana i nā hopena demagnetization a me ke kūpaʻa wela maikaʻi loa. E like me nā Neodymium Magnets, SmCo Magnes kekahi e koi i nā uhi e pale ai i ka corrosion. Eia naʻe, ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion ma mua o ka NdFeB. I loko o nā wahi ʻakika, pono e uhi ʻia nā SmCo Magnes. Hāʻawi ke kūpaʻa corrosion i ka hōʻoia no ka poʻe e noʻonoʻo ana e hoʻohana i nā magnet i nā noi olakino.
Hana maikaʻi ʻo NdFeB Magnet ma nā haʻahaʻa haʻahaʻa, ʻoiai ʻo SmCo Magnet e hana maikaʻi ma nā wela kiʻekiʻe. ʻO Neodymium Iron Boron Magnets ka ikaika mau loa ma ka lumi wela a hiki i ka 230 degere Celsius, i ana ʻia e ko lākou koena magnetism Br. Akā, emi koke ko lākou ikaika me ka piʻi ʻana o ka mahana. Ke hoʻokokoke ka mahana hana i 230 degere Celsius, hoʻomaka ka hana o ka samarium cobalt magnets e ʻoi aku ma mua o ka NdFeB.
ʻO SmCo Magnet ka lua o nā mea magnetic ikaika loa me ka mana anti-demagnetization maikaʻi loa, i hoʻohana nui ʻia i ka ʻoihana aerospace a i ʻole nā ʻoihana ʻoihana kahi mea nui ka hana a ʻo ke kumu kūʻai ke lua. ʻOi aku ka ikaika o nā SmCo Magnets i kūkulu ʻia i ka makahiki 1970Mākēneki Seramics (Ferrite Magnets)aNā Mākēneki Aluminum Nickel Cobalt (AlNiCo Magnets), akā ʻaʻole ikaika e like me nā Neodymium Magnets. Hoʻokaʻawale ʻia ʻo Samarium Cobalt Magnets i ʻelua mau ʻāpana, hoʻokaʻawale ʻia e ka ʻike ikehu. ʻO ka huahana ikehu o ka hui mua Sm1Co5 (i ʻike ʻia ʻo 1-5) a me ka laulā o ka hui ʻelua Sm2Co17 (2-17).

Hana Hana o SmCo Magnets
Kaʻana like nā SmCo Magnets a me Neodymium Magnets. Hoʻomaka lākou e like me nā metala pauka, i hui ʻia a hoʻopaʻa ʻia ma lalo o kahi māla ikaika. Hoʻopili ʻia nā mea i hoʻopaʻa ʻia e hana i nā magnet paʻa. I ka wā e pili ana i ka mīkini, pono nā mea ʻelua i ka hoʻohana ʻana i nā mea hana daimana, ka mīkini hoʻokuʻu uila, a i ʻole ka wili abrasive. Pono kēia mau kaʻina hana no ka hoʻokō ʻana i ke ʻano i makemake ʻia a me nā ana o nā magnet. ʻO ke kaʻina hana o SmCo (Samarium Cobalt) magnet e pili ana i kekahi mau pae:
Kaʻina pauka → Paʻi → Sintering → Hoʻāʻo waiwai magnetic → ʻoki → huahana i hoʻopau ʻia
SmCo Magnets ua maʻamau kaʻina ma lalo un-magnetized kūlana, me ka daimana wili huila a pulu maikai wili, i mea e pono ai. No ka haʻahaʻa haʻahaʻa wela, ʻaʻole pono e maloʻo loa nā SmCo Magnets. Hiki ke ho'āla maʻalahi i ke ahi, me ka wela kiʻekiʻe loa, he paʻakikī ke hoʻomalu.
