Indlela ozibuthe be-neodymium enziwa ngayo

Sizochaza ukuthi kanjaniIzibuthe ze-NdFeBzenziwe ngencazelo elula.Uzibuthe we-neodymium uwuzibuthe ongunaphakade owenziwe ngengxubevange ye-neodymium, insimbi, ne-boron ukuze akhe ukwakheka kwe-Nd2Fe14B tetragonal crystalline.Ozibuthe be-neodymium be-Sintered benziwa ngokushisisa nge-vacuum izinhlayiya zensimbi zomhlaba ezingavamile njengezisetshenziswa zokusetshenziswa esithandweni.Ngemuva kokuthola izinto zokusetshenziswa, sizokwenza izinyathelo eziyi-9 zokwenza omazibuthe be-NdFeB futhi ekugcineni sikhiqize imikhiqizo eqediwe.

Lungiselela izinto zokusabela, ukuncibilika, ukugaya, ukucindezela, ukucwilisa, umshini, ukucwenga, ukudonsa amandla kanye nokuhlola.

Lungiselela izinto zokusabela

Ifomu elihlanganisiwe lamakhemikhali likazibuthe we-neodymium yi-Nd2Fe14B.

Omazibuthe bavamise ukunotha ngo-Nd no-B, futhi omazibuthe abaqediwe ngokuvamile banezindawo ezingezona uzibuthe ze-Nd kanye ne-B kuzinhlamvu, eziqukethe i-Nd2Fe14B kazibuthe kakhulu.okusanhlamvu.Ezinye izakhi zomhlaba ezimbalwa ezingavamile zingangezwa esikhundleni se-neodymium ngokwengxenye: i-dysprosium, i-terbium, i-gadolinium, i-holmium, i-lanthanum, ne-cerium.Ithusi, i-cobalt, i-aluminium, i-gallium ne-niobium ingangezwa ukuthuthukisa ezinye izakhiwo zikazibuthe.Kuyinto evamile ukusebenzisa kokubili i-Co ne-D ndawonye.Zonke izakhi zokukhiqiza omazibuthe bebanga elikhethiwe zifakwa esithandweni sokungeniswa kwe-vacuum, sishisiswe futhi sincibilike ukwenza i-alloy material.

Iyancibilika

Izinto zokusetshenziswa zidinga ukuncibilika esithandweni sokungenisa ivacuum ukuze kwakheka ingxubevange ye-Nd2Fe14B.Umkhiqizo ushiswa ngokwakha i-vortex, konke kungaphansi kwe-vacuum ukuvimbela ukungcola ekungeneni kokusabela.Umkhiqizo wokugcina walesi sinyathelo ishidi elincanyana eliliribhoni (ishidi le-SC) elakhiwe ngamakristalu afanayo we-Nd2Fe14B.Inqubo yokuncibilika idinga ukwenziwa ngesikhathi esifushane kakhulu ukuze kugwenywe ukugcwala ngokweqile kwe-oxidation yezinsimbi zomhlaba ezingavamile.

Ukugaya

Isinyathelo esi-2 sokugaya sisetshenziswa ekusebenzeni kokukhiqiza.Isinyathelo sokuqala, esibizwa ngokuthi i-hydrogen detonation, sibandakanya ukusabela phakathi kwe-hydrogen ne-neodymium nge-alloy, kwephula ama-SC flakes abe yizinhlayiyana ezincane.Isinyathelo sesibili, esibizwa ngokuthi i-jet milling, siguqula izinhlayiya ze-Nd2Fe14B zibe yizinhlayiya ezincane, ezisukela kububanzi obusuka ku-2-5μm.Ukugaya i-Jet kunciphisa izinto eziwumphumela zibe yimpushana yosayizi wezinhlayiyana ezincane kakhulu.Usayizi wezinhlayiyana omaphakathi ungama-microns angu-3.

Iyacindezela

I-NdFeB powder icindezelwa ekubeni okuqinile esimweni esifiswayo endaweni enamandla kazibuthe.Okuqinile okucindezelwe kuzothola futhi kugcine umumo ozibuthe okhethwayo.Ngendlela ebizwa ngokuthi i-die-upsetting, impushana icindezelwa ibe into eqinile endaweni ecishe ibe ngu-725°C.Okuqinile bese kufakwa isikhunta sesibili, lapho kucindezelwa khona kube isimo esibanzi, cishe ingxenye yobude baso bokuqala.Lokhu kwenza isiqondiso samagnetization esithandwayo sihambisane nesiqondiso se-extrusion.Kumajamo athile, kunezindlela ezihlanganisa ama-clamp akhiqiza insimu kazibuthe ngesikhathi sokucindezela ukuqondisa izinhlayiya.

I-Sintering

Okuqinile kwe-NdFeB okucindezelwe kudinga ukucwiliswa ukuze kwakhiwe amabhulokhi e-NdFeB.Impahla icindezelwa emazingeni okushisa aphezulu (kufika ku-1080 ° C) ngaphansi kwendawo yokuncibilika yezinto kuze kube yilapho izinhlayiya zayo zihambisana nomunye nomunye.Inqubo ye-sintering iqukethe izinyathelo ezi-3: i-dehydrogenation, i-sintering kanye ne-temering.

Ukwenza imishini

Ozibuthe be-Sintered asikwa abe yizimo ezifiselekayo nosayizi kusetshenziswa inqubo yokugaya.Okungavamile, izimo eziyinkimbinkimbi ezibizwa ngokuthi izimo ezingavamile zikhiqizwa i-electrical discharge machining (EDM).Ngenxa yezindleko eziphezulu zezinto ezibonakalayo, ukulahleka kwempahla ngenxa yomshini kugcinwa kuncane.I-Huizhou Fullzen Technology inhle kakhulu ekukhiqizeni omazibuthe abangajwayelekile.

I-Plating/Coating

I-NdFeB engahlanganisiwe igqwalile kakhulu futhi ilahlekelwa uzibuthe wayo ngokushesha lapho imanzi.Ngakho-ke, wonke amamagnethi e-neodymium atholakala ngokuthengisa adinga ukunamathela.Ozibuthe ngamunye bahlanganiswe ngezigaba ezintathu: i-nickel, ithusi ne-nickel.Ukuze uthole ezinye izinhlobo zokumboza, sicela uchofoze okuthi “Xhumana nathi”.

Uzibuthe

Umazibuthe ubekwa endaweni eveza uzibuthe endaweni enamandla kazibuthe isikhathi esifushane.Ngokuyisisekelo ikhoyili enkulu esongwe umazibuthe.Amadivayisi azibuthe asebenzisa amabhange e-capacitor kanye nama-voltage aphezulu kakhulu ukuze athole amandla anjalo anamandla ngesikhathi esifushane.

Ukuhlola

Hlola izinga ozibuthe umphumela izici ezihlukahlukene.Iprojektha yokulinganisa yedijithali iqinisekisa ubukhulu.Amasistimu wokulinganisa ukushuba kokumboza asebenzisa ubuchwepheshe be-X-ray fluorescence aqinisekisa ukujiya kwezingubo.Ukuhlola okuvamile ekuhlolweni kwesifutho sikasawoti kanye neziko lokucindezelwa nakho kuqinisekisa ukusebenza kokunamathela.Imephu ye-hysteresis ikala ijika le-BH lamazibuthe, liqinisekisa ukuthi asebenza uzibuthe ngokugcwele, njengoba kulindelekile esigabeni sikazibuthe.

Ekugcineni sithole umkhiqizo ofanele uzibuthe.
