I-Neodymium Magnet, eyaziwa ngokuba ziimagnethi ezinqabileyo zomhlaba

Iimagnethi zeNeodymium, ezaziwa ngokuba ziimagnethi zomhlaba ezinqabileyo, ziye zabaluleke kakhulu kwiindawo ezininzi zobugcisa bale mihla ngenxa yeempawu zazo ezikhethekileyo zemagnethi.Ezi magnethi zisetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanywa i-electronics, izixhobo zonyango, i-aerospace, kunye namandla avuselelekayo.Kutshanje, iqela lezazinzulu ezivela kwiYunivesithi yaseTokyo lenze ubhaqo olunokuphucula kakhulu ukusebenza kweemagnethi ze-neodymium.

Kuphononongo olupapashwe kwijenali yeNdalo, abaphandi baxela ukuba baye bavelisa ngempumelelo umazibuthe we-neodymium kunye nokunyanzeliswa okuphezulu kunanoma yiyiphi i-neodymium echazwe ngaphambili.Ukunyanzeliswa ngumlinganiselo wokukwazi kwemagneti ukuxhathisa i-demagnetization, kwaye ukunyanzeliswa okuphezulu kubalulekile ekusebenzeni okuzinzileyo kwezixhobo ezininzi, kubandakanya iimotor zombane kunye neejenereyitha.

Ukufezekisa le mpumelelo, iqela lisebenzise ubuchule obubizwa ngokuba yi-spark plasma sintering, ebandakanya ukufudumeza okukhawulezileyo kunye nokupholisa umxube ongumgubo we-neodymium kunye ne-iron boron.Le nkqubo inceda ukulungelelanisa iinkozo zemagneti kwizinto eziphathekayo, eziye zandisa ukunyanzeliswa kwemagnethi.

Imagnethi entsha eveliswe ngabaphandi yayine-coercivity ye-5.5 tesla, emalunga ne-20% ephezulu kunomnini werekhodi wangaphambili.Olu phuculo olubalulekileyo lokunyanzeliswa lunokuba nezicelo ezininzi ezisebenzayo kwintsimi yeemoto zombane, ezisetyenziswa kumashishini amaninzi, kubandakanywa iimoto kunye ne-aerospace.

Abaphandi baphinde baqaphela ukuba imagnethi entsha yaveliswa ngokusebenzisa inkqubo elula kunye ne-scalable, enokwenza kube lula kwaye ingabizi kakhulu ukuvelisa i-high-performance neodymium magnets kwixesha elizayo.Oku kunokukhokelela ekuphuhlisweni kweenjini zombane ezisebenza ngokufanelekileyo nezithembekileyo kunye neejenereyitha, eziya kuba nempembelelo ebalulekileyo kumashishini amaninzi kwaye ezinokuba negalelo ekukhuleni kwemithombo yamandla avuselelekayo.

Ukuqukumbela, impumelelo yamva nje yophando lwemagnethi ye-neodymium yiYunivesithi yaseTokyo luphuhliso olubalulekileyo olunokuba nefuthe elifikelela kude kwimimandla emininzi yobuchwepheshe bale mihla.Ukukwazi ukuvelisa iimagnethi ze-neodymium ezisebenza ngokuphezulu kusetyenziswa inkqubo elula neyokucutheka kunokutshintsha imo yombane kunye neshishini lejenereyitha kwaye libe negalelo ekukhuleni kwemithombo yamandla avuselelekayo.
