Ua hele mai nā magnene i kahi lōʻihi mai nā lā o kou'ōpio i ka wā e hana aiʻoe i nā hola i hoʻopaʻaʻia i ka puka brigg. ʻOi aku ka ikaika o nā magnet i kēia lā ma mua o ko lākouʻano a me kā lākouʻano e hana ai iā lākou i nāʻano nui o nā noi.
Holo i ka Honua a me Cerramic magnets - nui loa ka honua ma nāʻoihana nui - loaʻa i nāʻoihana he nui a me nāʻoihana e hoʻonui houʻia. ʻOiai he nui nā mea nona nāʻoihana eʻike ana i kēia mau magnet, e hoʻomaopopo i ka mea e hiki ai iā lākou ke hoʻohālikelike. Eia kahi wikiwiki wikiwiki o nāʻokoʻa ma waena o nāʻanoʻelua o nā magnet o nā magnet, a me kahi synopsis o kā lākou pilina pili a me nā hemahema.
Ka hiʻuʻona
ʻO kēia mau mea ikaika ikaika loa i hakuʻia i kahi neodymium a iʻole samarium,ʻelua no nā mea maʻamau. Ua hoʻohana muaʻiaʻo Samarium i ka makahiki 1970, me Neodymium Magnet e hele mai ana i nā makahiki 1980. ʻO ka neodymiumʻelua a me Samarium ka nui o nā kelepona nui a hoʻohanaʻia i nā noi he nui a me nā mea hana ikaika loa a me nā mea hanaʻepekema.
Neodymium
I kekahi manawa ua kapaʻiaʻo NDFEB magnet no nā mea i loaʻa iā lākou - neodymium, hao a me Boron ʻO ka huahana nui loa (Bhmax) o kēia mau magnet, e hōʻike ana i ka ikaika o ka ikaika, hiki keʻoi aku ma mua o 50mgue.
ʻO kēlā bhnx kiʻekiʻe ʻO ka TMAX o nā neodymium magnets he 150 degals celseius, e pili ana i ka hapalua o kēlā me kēia chbarium a iʻole ka ceamic. (E nānā i ka mahana kūpono i nā magnet e nalowale ana i ko lākou ikaika i ka wā e hiki ai ke wela i ka wela.)
Hiki ke hoʻohālikelikeʻia nā magnet ma muli o kā lākou TCURIE. Ke hoʻomoeʻia nā magnenets i nā mahana ma mua o ko lākou tmax, ma ka hapa nui o lākou e ho'ōla hoʻokahi; ʻO ka TCURIE ka mahana ma mua o ka hoʻihoʻiʻana i hikiʻole ke ho'ōla. No kahi magnet neodymium ʻAʻole i hāpaiʻo Neodymium magnet i a iʻole ma mua o kēlā mahana e hiki ai ke hoʻomaikaʻi i ka hana i ka wā e noʻonoʻo ai. Loaʻa i nā mea kiʻekiʻeʻo Samarium a me nā ceramika i nā tcuries kiʻekiʻe, e hana ana iā lākou i kahi koho maikaʻi loa no nā noi kiʻekiʻe.
ʻO nā manina neodymium ma hope e lilo i ka hana demagnetized e nā mahina ma mua, akā hana lākou i ka hana i ka paleʻana i ka pale mai ka paleʻana.
Samani Conderat
ʻO CAMARIIRA COBALT, a iʻole Saco, ua lilo nā magnets i ka makahiki 1970, a mai laila, ua hoʻohanaʻia ko lākou mau palapala noi. ʻOiaiʻaʻole e like me ka ikaika e like me ka neodymium magnet ʻO ka TMAX o kahi Cambaum Corbat magnet he 300 degere Celdeius, a hiki i ka TCUrie ke like me ka 750 turding celseius. Ua hui pūʻia ko lākou ikaika pili me ko lākou hiki ke hana nui loa i nā kiʻekiʻe kiʻekiʻe e hana ai iā lākou no nā noi kiʻekiʻe. ʻAʻole like me Neodymium magnets,ʻo Samarium Cobal Magnet i loaʻa i ke kū'ēʻana i ke kūlike; Ua hana pū lākou i kahi kumukūʻai kiʻekiʻe ma mua o nā magnets neodymium.
Hana
I hanaʻia ma luna o ka pahu pahu a iʻole strontium, ua nui nā magnenets ma mua o nā magnet o nā magnet i nā makahiki 1960. ʻO nā mea nui loa nā magnenets ma mua o nā magnet o nā magnet i nā magnet a he ikaika paha lākou me kaʻumi a iʻole ma kahi o ka makma a iʻole ka hapa o ka neodymium.
E pili ana i ka wela, he mau tmax o nā cemic o 300 defess celseius a, e like me Samaria ʻO nā manika e nānā nui loa ana i ka corrosion a maʻamauʻaʻole pono e koi i kahi pale pale. He maʻalahi lākou e mare aʻoi aku ka nui o nā haʻahaʻa ma mua o ka neodymium a iʻole nā morlio cobat Eia nō naʻe, he mau Pelekaneʻo Cerammic, e hana ana iā lākou i kahi koho maikaʻiʻole no nā noi no nā noi e pili ana i keʻano nui a iʻole ke kaumaha. Hoʻohana pinepineʻia nā manina cemaric no nā hōʻike papaʻaina a me nā noi liʻiliʻi a me nāʻoihanaʻoihana a me nāʻoihanaʻoihana. Hiki paha iā lākou ke hoʻohanaʻia i nā noi home a ma ka hanaʻana o nā'āpana magnetic a me ka hōʻailona.
