I-Honsen Magneticsithengisa ngozibuthe be-neodymium abanelayisensi.Uzibuthe we-neodymium (owaziwa nangokuthi yi-NdFeB NIB noma uzibuthe we-Neo) uhlobo olusetshenziswa kakhulu lukazibuthe ovela emhlabeni, unguzibuthe ongunaphakade owenziwe ngengxubevange ye-neodymium, insimbi ne-boron ukuze akhe ukwakheka kwe-Nd2Fe14B tetragonal crystalline.Yasungulwa ngo-1982 ngabakwaGeneral Motors kanye neSumitomo Special Metals, omagnet be-neodymium bawuhlobo oluqine kakhulu lukazibuthe oluhlala njalo olutholakala ngokuthengiswa.Bathathele indawo ezinye izinhlobo zikazibuthe ezinhlelweni eziningi emikhiqizweni yesimanje edinga ozibuthe abaqinile abangapheli, njengamamotho kumathuluzi angenazintambo, amadrayivu wediski eliqinile nezixhumi kazibuthe.Awuqinisekile ukuthi i-Neodymium iyimpahla engcono kakhulu yohlelo lwakho lokusebenza?chofoza lapha ukuze uthole isibaluli kanye nokuqhathaniswa kwesicelo sakho konke okokusebenza kazibuthe esikunikezayo.
I-Neodymium eyindilinga uzibuthe unomphela Incazelo
Isakhiwo sekristalu se-tetragonal Nd2Fe14B sine-uniaxial magnetocrystalline anisotropy ephezulu kakhulu (HA~7 teslas-magnetic field amandla H ku-A/m uma kuqhathaniswa nomzuzu kazibuthe ku-A.m2).Lokhu kunikeza inhlanganisela amandla okuba nokuphoqelela okuphezulu (okungukuthi, ukumelana nokukhishwa uzibuthe).I-compound ibuye ibe ne-high saturation magnetization (Js ~ 1.6 T noma i-16 kG) futhi ngokuvamile i-1.3 teslas. Ngakho-ke, njengoba ubukhulu bamandla obukhulu bulingana ne-js2, lesi sigaba samagnetic sinamandla okugcina amanani amakhulu wamandla kazibuthe (BHmax ~ 512 kJ/m3 noma 64 MG·Oe) Lesi sakhiwo siphakeme kakhulu kuma-alloys e-NdFeB kunozibuthe be-samarium cobalt (SmCo), okwakuwuhlobo lokuqala lukazibuthe ovela emhlabeni olungavamile ukudayiswa.Empeleni, izici kazibuthe zikazibuthe we-neodymium zincike ekwakhiweni kwengxubevange, i-microstructure, nezindlela zokukhiqiza ezisetshenziswayo.n45 neodymium uzibuthe disc
