Neodymium Magnet, inozivikanwawo semagineti epasi asingawanzo

Magineti eNeodymium, anozivikanwawo semagineti epasi asingawanzo, ave kuwedzera kukosha munzvimbo zhinji dzetekinoroji yemazuva ano nekuda kweakasarudzika magineti.Aya magineti anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira zvemagetsi, zvekurapa, aerospace, uye simba rinogoneka.Munguva ichangopfuura, boka revasayendisiti kubva kuYunivhesiti yeTokyo rakaita chiziviso chepasi chinogona kuvandudza zvakanyanya kushanda kweneodymium magineti.

Muchidzidzo chakabudiswa mujenari Nature, vatsvakurudzi vakashuma kuti vakabudirira kugadzira neodymium magineti ine yakakwirira yekumanikidza kupfuura chero yakambotaurwa neodymium magineti.Coercivity chiyero chekugona kwemagineti kuramba demagnetization, uye yakakwirira coercivity yakakosha pakushanda kwakagadzikana kwemidziyo yakawanda, kusanganisira mota dzemagetsi uye jenareta.

Kuti zvibudirire uku, timu yakashandisa nzira inodaidzwa kuti spark plasma sintering, inosanganisira kukurumidza kudziyisa uye kutonhora kwemusanganiswa wehupfu we neodymium ne iron boron.Iyi nzira inobatsira kurongedza magineti zviyo muzvinyorwa, izvo zvinowedzera kumanikidza kwemagineti.

Iyo magineti nyowani inogadzirwa nevatsvaguri yaive ne coercivity ye 5.5 tesla, iyo inenge 20% yakakwirira kupfuura yekare inobata rekodhi.Kuvandudzwa kwakakosha uku mukumanikidza kunogona kuve nekushandisa kwakawanda kunoshanda mumunda wemagetsi emagetsi, ayo anoshandiswa mumaindasitiri mazhinji, anosanganisira emotokari uye aerospace.

Vatsvakurudzi vakacherechedzawo kuti magineti matsva akagadzirwa achishandisa nzira iri nyore uye inogadziriswa, iyo inogona kuita kuti zvive nyore uye zvinodhura zvakanyanya kugadzira magineti e-neodymium akakwirira mune ramangwana.Izvi zvinogona kutungamira mukugadzirwa kwemagetsi emagetsi anoshanda uye anovimbika uye majenareta, izvo zvingave zvine chekuita nemaindasitiri mazhinji uye zvinogona kubatsira mukukura kwesimba rinowanikwazve.

Mukupedzisa, budiriro ichangoburwa mu neodymium magineti tsvagiridzo neYunivhesiti yeTokyo ibudiriro huru inogona kuve nemhedzisiro inosvika kure kunzvimbo zhinji dzehunyanzvi hwemazuva ano.Iko kugona kugadzira epamusoro-inoshanda neodymium magineti uchishandisa yakapusa uye inokatyamadza maitiro anogona kushandura indasitiri yemagetsi nejenareta uye kubatsira mukukura kwesimba rinogonekazve.
