Ukwakhiwa kweSamarium Cobalt Permanent Magnets
Uzibuthe we-Samarium cobalt unomphela uyizibuthe zomhlaba ezingavamile, ikakhulukazi ezakhiwe nge-metal samarium (Sm), i-cobalt yensimbi (Co), ithusi (Cu), insimbi (Fe), i-zirconium (Zr) nezinye izakhi, kusukela esakhiweni ihlukaniswe yaba yi-1. :5 uhlobo no-2:17 uhlobo lwesibili, kungokwesizukulwane sokuqala kanye nesizukulwane sesibili sezinto ezingavamile zikazibuthe zomhlaba ezihlala unomphela. Uzibuthe we-Samarium cobalt unomphela unezakhiwo ezinhle kakhulu zikazibuthe (i-remanence ephezulu, amandla aphezulu kanye nomkhiqizo wamandla kazibuthe), i-coefficient ephansi kakhulu yokushisa, izinga lokushisa eliphakeme lenkonzo kanye nokumelana nokugqwala okuqinile, iyona nto engcono kakhulu yamagnetic ukumelana nezinga lokushisa, esetshenziswa kabanzi kumadivayisi we-microwave, i-electron. amadivaysi ensimbi, amandla aphezulu/amamotho anesivinini esikhulu, izinzwa, izingxenye kazibuthe nezinye izimboni.
Umsebenzi 2:17 uzibuthe samarium-cobalt
Omunye wamazibuthe we-samarium-cobalt odume kakhulu uzibuthe ongu-2:17 samarium-cobalt, uchungechunge lozibuthe abaziwa ngezici zabo eziphakeme kazibuthe, okubenza babe ukukhetha kokuqala kwezinhlelo zokusebenza ezidinga amandla kazibuthe aphezulu nokuzinza.
Kusukela ezicini zokusebenza, 2:17 samarium-cobalt odonsa unomphela angahlukaniswa ngochungechunge olusebenza kahle kakhulu, uchungechunge oluqinile lokuzinza (i-coefficient ephansi yokushisa) nochungechunge lokumelana nokushisa okuphezulu. Inhlanganisela eyingqayizivele yokuqina kwamandla kazibuthe, ukuzinza kwezinga lokushisa kanye nokumelana nokugqwala kwenza ozibuthe be-samarium-cobalt balungele ukusetshenziswa okuhlukahlukene, okubandakanya amamotho kagesi, izinzwa, ukuhlangana kazibuthe kanye nezihlukanisi kazibuthe.
Ibanga eliphezulu lomkhiqizo wamandla kazibuthe ebangeni ngalinye liphakathi kuka-20-35MGOe, futhi izinga lokushisa eliphakeme kakhulu lokusebenza ngu-500 ℃. Ozibuthe be-Samarium-cobalt unomphela banenhlanganisela eyingqayizivele ye-coefficient yokushisa ephansi kanye nokumelana nokugqwala okuhle, amandla kazibuthe aphezulu, ukuzinza kwezinga lokushisa kanye nokumelana nokugqwala, okwenza ozibuthe be-samarium-cobalt baphelele ezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi ama-motor kagesi, izinzwa, kazibuthe. ama-couplings kanye nezihlukanisi kazibuthe. Izakhiwo kazibuthe zozibuthe be-Ndfeb emazingeni okushisa aphezulu zidlula omazibuthe be-NdFeb, ngakho-ke zisetshenziswa kakhulu endaweni yezindiza, izinkundla zempi, amamotho okushisa aphezulu, izinzwa zezimoto, amadrayivu ahlukahlukene kazibuthe, amaphampu kazibuthe namadivayisi we-microwave. 2:17 uhloboamamagnethi we-samarium cobalt ama-brittle ngokwedlulele, akulula ukuwacubungula abe yizimo eziyinkimbinkimbi noma ikakhulukazi amashidi amancane namasongo anezindonga ezincane, ngaphezu kwalokho, kulula ukubangela amakhona amancane enqubweni yokukhiqiza, ngokuvamile inqobo nje uma angathinti izakhiwo kazibuthe noma imisebenzi, ingathathwa njengemikhiqizo efanelekile.
Kafushane, amamagnethi ahlala njalo e-samarium cobalt, ikakhulukazi uchungechunge lwamandla kazibuthe aphezuluOzibuthe be-Sm2Co17, baziswa kakhulu ngenxa yezakhiwo zabo ezinhle kakhulu kazibuthe nokuzinza. Ikhono lazo lokumelana namazinga okushisa aphezulu kanye nezindawo ezinokhahlo lizenza zibe ukukhetha kokuqala kokufuna izicelo ezimbonini zonkana. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, isidingo samagnetic we-samarium-cobalt unomphela kulindeleke ukuthi sikhule, siqinise isikhundla sabo njengengxenye ebalulekile yezicelo zesimanje zezimboni nezentengiso.
