Okwamanje, izinto ezivamile kazibuthe unomphela uzibuthe ferrite,NdFeb uzibuthe, Uzibuthe we-SmCo, Uzibuthe we-Alnico, uzibuthe wenjoloba nokunye.Lezi kulula ukuzithenga, ngokusebenza okuvamile (hhayi izindinganiso ze-ISO) ongakhetha kuzo.Imagnethi ngayinye engenhla inezici zayo kanye nezinkambu ezihlukene zohlelo lokusebenza, okwethulwa kafushane kanje.
Uzibuthe we-Neodymium
I-NdFeb inguzibuthe esetshenziswa kabanzi futhi ithuthuka ngokushesha.
Uzibuthe we-Neodymium usetshenziswa kabanzi kusukela ekusungulweni kuze kube manje, kodwa futhi eminyakeni engaphezu kwengu-20.Ngenxa yezakhiwo zayo eziphakeme kazibuthe nokucutshungulwa okulula, futhi intengo ayiphezulu kakhulu, ngakho insimu yesicelo ikhula ngokushesha.Njengamanje, i-NdFeb yezohwebo, umkhiqizo wayo wamandla kazibuthe ungafinyelela ku-50MGOe, futhi iyizikhathi eziyi-10 ze-ferrite.
I-NdFeb futhi ingumkhiqizo we-powder metallurgy futhi icutshungulwa ngendlela efanayo ne-samarium cobalt magnet.
Njengamanje, izinga lokushisa eliphezulu lokusebenza kwe-NdFeb licishe libe ngu-180 degrees Celsius.Ngezinhlelo zokusebenza ezinzima, ngokuvamile kunconywa ukuthi ungeqi ku-140 degrees Celsius.
I-NdFeb igqwalile kalula.Ngakho-ke, iningi lemikhiqizo eqediwe kufanele ifakwe i-electroplated noma iboshwe.Ukwelashwa kwendawo evamile kuhlanganisa i-nickel plating (nickel-copper nickel), i-zinc plating, i-aluminium plating, i-electrophoresis, njll. Uma usebenza endaweni evaliwe, ungasebenzisa futhi i-phosphating.
Ngenxa yezakhiwo eziphakeme kazibuthe ze-NdFeb, ezikhathini eziningi, isetshenziselwa ukufaka esikhundleni sezinye izinto zikazibuthe ukuze kuncishiswe umthamo wemikhiqizo.Uma usebenzisa omagnethi be-ferrite, ubukhulu befoni ephathekayo yamanje, ngiyesaba hhayi ngaphansi kwesigamu sesitini.
Ozibuthe ababili abangenhla banokusebenza okungcono kokucubungula.Ngakho-ke, ukubekezelelana kwe-dimensional komkhiqizo kungcono kakhulu kune-ferrite.Ngemikhiqizo ejwayelekile, ukubekezelelana kungaba (+/-)0.05mm.
Uzibuthe we-Samarium Cobalt
Ozibuthe baseSamarium cobalt, izithako eziyinhloko yi-samarium ne-cobalt.Ngenxa yokuthi intengo yezinto zokwakha iyabiza, omagnethi be-samarium cobalt bangenye yezinhlobo ezibiza kakhulu.
Umkhiqizo wamandla kazibuthe wamazibuthe we-samarium cobalt okwamanje ungafinyelela ku-30MGOe noma ngaphezulu.Ngaphezu kwalokho, omagnethi be-samarium cobalt banempoqo futhi bamelana nokushisa okuphezulu, futhi bangasetshenziswa emazingeni okushisa afinyelela ku-350 degrees Celsius.Ukuze ingenakuthathelwa indawo ezinhlelweni eziningi
I-Samarium cobalt magnet ingeyemikhiqizo ye-powder metallurgy.Abakhiqizi abajwayelekile ngokuya ngosayizi kanye nokuma kwezidingo zomkhiqizo oqediwe, bashiswe endaweni engenalutho yesikwele, bese besebenzisa i-blade yedayimane ukusika usayizi womkhiqizo osuphelile.Ngenxa yokuthi i-samarium cobalt i-electrical conductive, ingasikwa ngokuqondile.Ngokweqile, i-samarium cobalt ingasikwa ibe yisimo esingasikwa ngokulandelana, uma i-magnetization kanye nosayizi omkhulu kungabhekwa.
Ozibuthe be-Samarium cobalt banokumelana nokugqwala okuhle kakhulu futhi ngokuvamile abadingi i-anti-corrosion plating noma ukunamathela.Ngaphezu kwalokho, omazibuthe be-samarium cobalt bane-brittle, kunzima ukwenza imikhiqizo ngamasayizi amancane noma izindonga ezincane.
Uzibuthe we-Alnico
I-Alnico magnet inezindlela ezimbili ezihlukene zokusakaza nokufaka.Umkhiqizo wasekhaya osakaza kakhulu i-Alnico.Umkhiqizo wamandla kazibuthe we-Alnico uzibuthe ungafinyelela ku-9MGOe, futhi unesici esikhulu esiwukuthi ukumelana nokushisa okuphezulu, izinga lokushisa lokusebenza lingafinyelela ku-550 degrees Celsius.Kodwa-ke, uzibuthe we-Alnico kulula kakhulu ukukhipha uzibuthe endaweni yamagnetic ehlanekezelwe.Uma uphusha izigxobo zikazibuthe ezimbili ze-Alnico ohlangothini olulodwa (o-N ababili noma o-S ababili) ndawonye, inkambu yomunye womazibuthe izohoxiswa noma ihlehliswe.Ngakho-ke, ayifaneleki ukusebenza endaweni kazibuthe ehlanekezelwe (njengemoto).
I-Alnico inobulukhuni obuphezulu futhi ingagaywa futhi isikwe ngocingo, kodwa ngezindleko eziphakeme.Ukunikezwa okujwayelekile kwemikhiqizo eqediwe, kunezinhlobo ezimbili zokugaya okuhle noma ukungagayi.
Uzibuthe weFerrite / Uzibuthe weCeramic
I-Ferrite iwuhlobo lwe-nonmetallic magnetic material, eyaziwa nangokuthi i-ceramics magnetic.Sihlukanisa umsakazo ojwayelekile, kanti uzibuthe okhona kuwo uyi-ferrite.
Izakhiwo kazibuthe ze-ferrite aziphakeme, umkhiqizo wamanje wamandla kazibuthe (enye yemingcele yokukala ukusebenza kukazibuthe) ungenza kuphela i-4MGOe ephakeme kancane.Impahla inenzuzo enkulu yokuba eshibhile.Okwamanje, isasetshenziswa kabanzi emikhakheni eminingi
I-Ferrite yi-ceramic.Ngakho-ke, ukusebenza kwemishini kufana nokwe-ceramics.Omazibuthe be-Ferrite bakha isikhunta, baphuma ngaphandle.Uma kudingekile ukucubungula, ukugaya okulula kuphela kungenziwa.
Ngenxa yobunzima bokucutshungulwa komshini, ngakho-ke iningi lokuma kwe-ferrite lilula, futhi ukubekezelelana kosayizi kukhulu kakhulu.Imikhiqizo yomumo wesikwele mihle, ingagaywa.Indilinga, ngokuvamile igaya izindiza ezimbili kuphela.Okunye ukubekezelelana kwe-dimensional kunikezwa njengephesenti lobukhulu obujwayelekile.
Ngenxa yokuthi uzibuthe we-ferrite usetshenziselwe amashumi eminyaka, abakhiqizi abaningi banamasongo enziwe ngomumo, izikwele neminye imikhiqizo yobumo nobukhulu obujwayelekile okufanele bayikhethe.
Ngenxa yokuthi i-ferrite iyimpahla ye-ceramic, empeleni ayikho inkinga yokugqwala.Imikhiqizo eqediwe ayidingi ukwelashwa okungaphezulu noma ukunamathela njenge-electroplating.
