ʻO nā mea magnet paʻa he ʻano hou o ka mea magnetic, ʻike ʻia hoʻi he mea magnetic paʻakikī. A ʻo NdFeb mau mea paʻa paʻa ke kolu o ka hanauna o nā mea hoʻonaninani mau loa, hiki i kāna noi ke hoʻemi nui i ka leo a me ka maikaʻi o ka mīkini, e like me ka noi disk, hiki ke hana i ka miniaturization disk drive, a ʻoi aku ka maikaʻi o ka hana. Ma nā leo leo, hoʻohana nui ʻia ʻo NdFeb i nā micro speakers, earphones a me nā leo kaʻa kiʻekiʻe, e hoʻomaikaʻi nui ana i ka pono leo a me ka ratio signal-to-noise. Eia kekahi, hiki ke hoʻohana ʻia i ka motor DC a me ka NUCLEAR magnetic resonance imaging, ʻoi aku hoʻi i ka hoʻohana ʻana i ke kaʻa levitation magnetic ʻaʻole wale i ka helu nui, akā hiki ke hoʻokō i ka halihali kiʻekiʻe, palekana, hilinaʻi a me nā ʻano haʻahaʻa haʻahaʻa.
No ka hōʻuluʻulu ʻana, ʻo NdFeb kahi mea hou ʻenehana kiʻekiʻe, a ʻo NdFeb ke ʻano hana hoʻoheheʻe paʻa mau loa he ʻano sintering a me ke ʻano hoʻopaʻa ʻana, i ke ʻano ʻano hoʻopuka. Hoʻohana ʻo Sintered NdFeb i ke kaʻina hana metallurgy pauka, ʻoluʻolu a porous ka ʻili, a ʻo ka palena o ka palaoa he neodymium-rich phase potential ka maikaʻi ʻole, no laila ʻilihune loa ka pale ʻana o ka corrosion, ʻo ka magnet mau loa ma hope o ka corrosion e hoʻopilikia nui i kona mau waiwai magnetic a me ke ola lawelawe. .
I kēia manawa,ʻo ka hoʻohanaʻana i keʻano electroplating e hāʻawi i kahi pale pale ma kaʻili o NdFeb,ʻo ka uhi kiʻekiʻe ka hōʻoiaʻiʻo o ke kūlana kiʻekiʻe a me ke ola lōʻihi o NdFeb mau loa. Hiki ke ʻike ʻia ʻo ka NdFeb paʻa paʻa hou e pili kokoke ana i ka ʻoihana mālama honua, a ʻo kēia ʻoihana, ua hauʻoli ʻo Xinfeng magnetic material i kahi inoa kiʻekiʻe ma ka ʻoihana.
