I-NDFEB WARNED

Sintered NdFeB odonsa uzilungiselele izinto zokusetshenziswa kokuba elicibilikile esithandweni, waphonsa efolomeni futhi selehlile ifomu ingots. I ingots kuthiwa ziyacolwa nepepper; powder is ke sintered ku amabhlogo obukhulu. Amabhulokhi ke ukushisa kabi, cut ngabobunjwa, ebusweni iphathwa kanye uzibuthe.

Kusukela ngomhla ka-2012, 50,000 amathani neodymium odonsa akhiqizwa ngokusemthethweni unyaka ngamunye eChina, kanti amathani 80,000 endaweni "inkampani-by-inkampani" Ukwakha-up kwenziwe ngo-2013 China likhiqiza 95% emhlabeni izakhi ezingavamile, futhi ukhiqiza cishe 76% wenani ezingavamile-umhlaba odonsa emhlabeni.

odonsa Neodymium kuthiwa letihlungiwe ngokuvumelana namandla umkhiqizo wabo esiphezulu, okuhlobene kazibuthe ecucuza okukhipha per unit ivolumu. Amanani Ephakeme abonisa odonsa namandla futhi isukela N35 kuze kube N52. Izinhlamvu ezilandelayo ebangeni abonisa esiphezulu okushisa yokusebenza (ngokuvamile izinga lokushisa Curie), asukela M (kufika ku 100 ° C) ukuze EH (200 ° C).

Sintered Nd2Fe14B ivame ukuba sengozini ukugqwala, ikakhulukazi kanye okusanhlamvu imingcele uzibuthe sintered. Lolu hlobo lwe-ukugqwala kungabangela ukuwohloka abucayi, kuhlanganisa ebhidlikayo ka uzibuthe lube impuphu izinhlayiya ezincane uzibuthe, noma i spallingof ungqimba ebusweni.
Lokhu sengozini siyanakekelwa imikhiqizo eminingi commercial ngokungeza enamathela ovikelayo ukuvimbela ukuchayeka emkhathini. Nickel Plating noma ezimbili-egqinsiwe zethusi-nickel Plating izindlela ejwayelekile, nakuba Plating nezinye izinsimbi noma polymer futhi lacquer ezinengilazi zokuzivikela futhi lisetshenziswa.

odonsa Neodymium esikhundleni alnico futhi odonsa ferrite e eziningi kwezicelo inqwaba kwezobuchwepheshe banamuhla lapho odonsa eqinile unomphela ziyadingeka, ngoba amandla abo mkhulu evumela ukusetshenziswa ezincane, odonsa lula isicelo inikezwe. Ezinye izibonelo yilezi:
actuators Head yekhompyutha angaphandle kanzima
Magnetic resonance imaging (MRI)
Mechanical e-ugwayi labadubuli ukushintshwa
Locks ngoba iminyango
Loudspeakers futhi ama-headphone
amabombo Magnetic futhi couplings
motors Electric:
amathuluzi Cordless
Servomotors
Lifting kanye compressor motors
motors Synchronous
Spindle kanye motors stepper
Electrical amandla ayo
motors Drive for hybrid izimoto kagesi. I motors kagesi ngayinye Toyota Prius zidinga 1 kilogram (2.2 pounds) ka neodymium.
Actuators
ugesi Electric ngoba ophephela abaphehla ugesi (kuphela labo unomphela uzibuthe excitation)
Direct-drive ophephela abaphehla ugesi zidinga c. 600 kg PM impahla megawatt ngayinye
Turbines usebenzisa amagiya zidinga kancane impahla PM megawatt ngayinye
