Ukuhlelwa kweeMagnethi zeNeodymium
Ngokuxhomekeke kwindlela yokuvelisa esetyenzisiweyo, imathiriyeli yeMagnet yeNeodymium inokwahlulwa ibeI-Sintered NeodymiumkwayeI-Neodymium edibeneyo. I-Bonded Neodymium inemagnetism kuwo onke amacala kwaye iyamelana nokuhlwa; I-Sintered Neodymium ithanda ukubola kwaye ifunaukutyabekakumphezulu wayo, ngokubanzi kuquka i-zinc plating, i-nickel plating, i-zinki ehambelana nokusingqongileyo, i-nickel friendly friendly plating, i-nickel copper nickel plating, i-nickel ye-nickel ye-copper ehambelana nokusingqongileyo, njl njl.izicelokwiimpahla zangoku ezifuna iimagnethi ezinamandla ezisisigxina, ezifana neenjini zombane kwizixhobo ezingenazintambo, ii-hard disk drives, kunye neziqhoboshi zemagnethi, zithathe indawo yezinye iintlobo zemagnethi.
Olona hlobo luxhaphakileyo lweMazibuthe yeRare-Earth yiNeodymium Magnet, edla ngokubizwa ngokuba yi-aNdFeB, NIB, okanye Neo umazibuthe. I-Neodymium, i-Iron, kunye ne-Boron ziye zadityaniswa ukuze zenze i-Permanent Magnet's Nd2Fe14B ye-tetragonal crystalline structure. I-Neodymium Magnets lolona hlobo lunamandla lweMagnet eSisigxina okwangoku kwimarike. Zaye zaphuhliswa ngokwahlukeneyo ngo-1984 nguGeneral Motors kunye neSumitomo Special Metals.
Neodymium Magnetyimathiriyeli elukhuni ngokwentelekiso enoxinano oluphantsi kodwa iipropathi zoomatshini eziphezulu, kwaye iindleko zayo zokuvelisa zingaphantsi kunezinye iMathiriyeli yeMazibuthe eZisigxina eziRare Earth. Okwangoku, ngokusekwe kuthelekiso oluthe tyaba lwesabelo semarike kunye nesizukulwana sesithathu seZixhobo zeMagnet eziQhelekileyo zoMhlaba, iNeodymium Magnets inesona sabelo semarike siphezulu kunye nemveliso yonyaka, esezantsi kuphela kunexabiso eliphantsi.Iimagnethi zeFerrite.

Kwimveliso yobukrelekrele, ukuqhuba ngobukrelekrele, nokumelwa ziirobhothi.Usetyenzisokwiindawo ezifana neenkonzo zobukrelekrele ziyanda.
I-Bonded Neodymium Magnets
I-Bonded Neodymium Magnet luhlobo lwezinto ezidityanisiweyo zemagnethi ezisisigxina ezenziwe ngokudibanisa ngokukhawuleza i-nanocrystalline neodymium iron boron powder magnetic enepolymer ephezulu (efana ne-thermosetting epoxy resin, iiplastiki zobunjineli be-thermoplastic, njl. njl.) njengesibophelelo, sahlulwe sabaI-Bonded Neodymium Compressed MagnetskwayeI-Bonded Neodymium Injection Magnets. Inomgangatho ophezulu kakhulu wokuchaneka, ukufana okuhle kwemagnethi, kunye nokungaguquguquki, kwaye inokwenziwa ibe ziimilo ezintsonkothileyo ekunzima ukufikelela kuzo kwiimagnethi ze-sintered neodymium kwaye kulula ukudityaniswa nezinye izinto zentsimbi okanye zeplastiki ukwenza. I-Bonded Neodymium Magnets ikwanazo iindlela ezahlukeneyo zemagneti, ilahleko ephantsi ye-eddy yangoku, kunye nokuxhathisa okuqinileyo ku-corrosion.
I-Bonded Neodymium Magnets isetyenziswa ikakhulu kumashishini ethekhnoloji yolwazi afana ne-computer hard drives kunye ne-optical disc drive spindle motors, ii-printer/copier motors, kunye ne-magnetic rollers, kunye nezixhobo zokuqhuba kunye nolawulo lokuguquguquka okuguquguqukayo kwezixhobo zasekhaya ezigcina amandla kunye nombane wabathengi. Ukusetyenziswa kwabo kwiimotor ezincinci kunye nezikhethekileyo kunye nezinzwa zezithuthi zamandla amatsha ngokuthe ngcembe zisiba yintengiso ephambili evelayo.
Ingcaciso Yamandla
I-Neodymium yintsimbi ye-antiferromagnetic ebonisa iimpawu zemagnethi xa inyulu, kodwa kuphela kumaqondo obushushu angaphantsi kwe-19 K (254.2 °C; 425.5 °F). Iikhompawundi ze-Neodymium ezineentsimbi eziguqukayo ze-ferromagnetic njengentsimbi, ezinobushushu beCurie ngaphezulu kobushushu begumbi, zisetyenziselwa ukwenza imagnethi ye-neodymium.
Amandla emagnethi eNeodymium yindibaniselwano yezinto ezahlukeneyo. Eyona nto ibalulekileyo yi-uniaxial magnetocrystalline anisotropy ephezulu kakhulu ye-tetragonal Nd2Fe14B isakhiwo sekristale (HA 7 T - amandla emagnethi e-H kwiiyunithi ze-A/m ngokuchasene nomzuzu wemagnethi kwi-Am2). Oku kubonisa ukuba ikristale yento yenza imagnethi ngokukhethayo ecaleni kwe-crystal axis ethile kodwa ikufumanisa kunzima kakhulu ukwenza imagneti kwezinye iindawo. I-alloy yemagnethi ye-neodymium, njengabanye oomazibuthe, yenziwe ngeenkozo ze-microcrystalline ezithi ngexesha lokwenziwa kokwenziwa zilungelelaniswe kwindawo eyomeleleyo yemagnethi ukuze ii-axes zazo zemagneti zikhombe kwicala elinye. Ikhompawundi inonyanzeliso oluphezulu kakhulu, okanye ukuxhathisa kwi-demagnetization, ngenxa yokuxhathisa kwekristale kwilathisi ekutshintsheni kwicala layo lemagnethi.
Ngenxa yokuba iqulethe ii-electron ezine ezingasebenziyo kwisakhiwo sayo se-electron xa kuthelekiswa (ngokomndilili) ezintathu kwintsimbi, i-athomu ye-neodymium iyakwazi ukuba nomzuzu obalulekileyo we-dipole. Ii-electron ezingabhangqwanga kwimagnethi ezilungelelanisiweyo ukuze ii-spins zazo zijonge kwicala elifanayo zivelise umhlaba wemagnethi. Oku kubangela i-saturation magnetization enamandla kwindibaniselwano ye-Nd2Fe14B (Js 1.6 T okanye i-16 kG) kunye ne-magnetization eyintsalela ye-1.3 teslas. Ngenxa yoko, esi sigaba samagnetic sinamandla okugcina amanani amakhulu ombane wamagnetic (BHmax 512 kJ / m3 okanye 64 MGOe), njengoko ubuninzi bamandla obuphezulu bulingana ne-Js2.
Eli xabiso lamandla omagnetic lijikeleze amaxesha angama-18 ngomthamo kunye namaxesha angama-12 ngobunzima obukhulu kune "rhoqo"iimagnethi zeferrite. I-Samarium cobalt (SmCo), Imagnethi yokuqala efumaneka ngokurhweba enqabileyo yomhlaba, inomgangatho ophantsi woluphawu lwamandla kazibuthe kune-NdFeB alloys. Iimpawu zemagnethi zeNeodymium zemagnethi ziphenjelelwa ngokwenene yi-microstructure yealloy, inkqubo yokuvelisa, kunye nokwakheka.
Iiathomu zentsimbi kunye nendibaniselwano ye-neodymium-boron ifumaneka kwezinye iileya ngaphakathi kwesakhiwo sekristale se-Nd2Fe14B. Iiathom ze-diamagnetic boron zikhuthaza umanyano ngokusebenzisa iibhondi eziqinileyo kodwa azinagalelo ngokuthe ngqo kwimagnetism. Imagnethi ye-Neodymium inexabiso eliphantsi kunemagnethi ye-samarium-cobalt ngenxa yoxinzelelo olusezantsi olunqabileyo lomhlaba (i-12% ngomthamo, i-26.7% ngobunzima), kunye nokufumaneka kwe-neodymium kunye nentsimbi xa kuthelekiswa ne-samarium kunye ne-cobalt.

Iingxaki zoMhlwa
Imida eziziinkozo zemagnethi ene-sintered isengozini yokubola kwi-Sintered Nd2Fe14B. Olu hlobo lomhlwa lunokukhokelela kumonakalo obonakalayo, njengokuqhekeka komgangatho ongaphezulu okanye ukuwohloka kwemagnethi ibe ngumgubo wamasuntswana amancinane azibuthe.
Iimpahla ezininzi zorhwebo zijongana nalo mngcipheko ngokuquka isigqubuthelo esikhuselayo ukunqanda ukuchanabeka kokusingqongileyo. Ezona platings zixhaphakileyo yi-nickel, nickel-copper-nickel, kunye ne-zinc, ngelixa ezinye iintsimbi zinokusetyenziswa, njengoko zinokukhusela i-polymer kunye ne-lacquer.iingubo.
Iimpembelelo zobushushu
I-Neodymium ine-coefficient engalunganga, oku kuthetha ukuba xa izinga lokushisa liphakama, zombini ukunyanzeliswa kunye nobuninzi be-magnetic energy density (BHmax) yehla. Kwiqondo lobushushu be-ambient, imagnethi ye-neodymium-iron-boron inonyanzeliso oluphezulu; nangona kunjalo, xa ubushushu bonyuka ngaphezu kwe-100 °C (212 °F), i-coercivity yehla ngokukhawuleza ide ifike kubushushu beCurie, obujikeleze i-320 °C okanye i-608 °F. Oku kuncipha kokunyanzeliswa kunqanda ukusebenza kwemagnethi kwizicelo zobushushu obuphezulu njengeeinjini zomoya, iinjini ezixubileyo, njl.njl. Ukunqanda ukusebenza ekuweni ngenxa yokuguquguquka kobushushu, i-terbium (Tb) okanye i-dysprosium (Dy) yongezwa, okonyusa iindleko umazibuthe.
