Pehea ka ikaika o ka momi o NdFeB ikaika ikaika?

Pehea ikaika anei ka mimi o NdFeB ikaika magnet?

NdFeB ʻO nā magnet ka mea ikaika loa i kēia manawa. ʻO nā mea magnet NdFeB i kēia manawa nā magnets loaʻa i ke kālepa. Ua ʻike ʻia lākou he mōʻī o ka magnetism. Loaʻa iā lākou nā waiwai magnetic kiʻekiʻe loa a me kā lākou kiʻekiʻe ʻOi aku ka 10 mau manawa kiʻekiʻe ma mua o ka huahana ikehu magnetic (BHmax). ferrite. ʻO ia hoʻi ka mea hoʻohana maʻamau i ka honua i kēia manawa, a ʻo ia hoʻohana ʻia i nā ʻāpana he nui a me nā mea kani e like me kā mākou magnet mau loa nā kaʻa kaʻa, nā disk drives, a me nā kiʻi resonance magnetic.

nona iho maikaʻi nō hoʻi ka machinability. Hiki ke piʻi ka mahana hana a hiki i 200 degere Celsius. Eia kekahi, paʻakikī kona ʻano, kūpaʻa kāna hana, a he maikaʻi ke kumu kūʻai, no laila ākea loa kāna noi. Akā ma muli o kāna hana kemika ikaika, pono e mālama ʻia me ka ʻili ka uhi ʻana. (Pēlā me Zn, Ni plating, electrophoresis, passivation, etc.).

ʻO ka mea nui ʻO ka ʻāpana o nā mākēneki NdFeB he neodymium ʻeleʻele honua. ʻAʻole ʻo Rare Earth kapa ʻia ʻo rare earth no ka haʻahaʻa haʻahaʻa, akā ʻoi aku ka paʻakikī kaʻawale ma mua o nā mea ʻē aʻe i hoʻopili ʻia e nā mea paʻa kemika. ʻOiai ka He ikaika loa ka hukihuki ʻana o NdFeB, a ua lohe ʻia Hiki i nā mea magnet NdFeB ke komo i 600 manawa i ko lākou kaumaha ponoʻī. Akā ʻoiaʻiʻo, ʻo kēia ʻAʻole paʻa ka ʻōlelo, no ka mea, ʻo ka mea hoʻonaninani magnetic kekahi pili i nā kūlana he nui e like me ke ʻano a me ka mamao. No ka laʻana, no nā magnet me ke anawaena like, ʻoi aku ka kiʻekiʻe o ka magnet, ʻoi aku ka ikaika o ka ikaika hoʻohihi magnetic; no na magnet me ke kiekie hookahi, o ka nui o ka ke anawaena, ʻoi aku ka nui o ka mana hoʻohihi magnetic.
