Izinzuzo kanye nokubi Sm2Co17 kanye SmCo5 unomphela magnetic materials

Uma kuqhathaniswa ne-SmCo5, iI-Sm2Co17inezinzuzo ezilandelayo:

1. Okuqukethwe kwe-cobalt ne-samarium kufomula ye-Sm2Co17 impahla kazibuthe unomphela iphansi kunaleyo ye-SmCo5 yezinto ezibonakalayo ezinozibuthe ezihlala njalo, ezisindisa kakhulu izindleko zezinto zokusetshenziswa.Ngenxa yokuthi i-samarium ne-cobalt izinto zokusetshenziswa ziyizinsimbi ezingavamile ezibiza kakhulu, ngakho-ke intengo ye-Sm2Co17 yezinto ezibonakalayo zikazibuthe unomphela iphansi kunaleyo ye-SmCo5;

2. I-coefficient yamagnetic yokungeniswa kwezinga lokushisa ye-Sm2Co17 impahla kazibuthe unomphela icishe ibe -0.02%/℃, ingasebenza ebangeni elingu -60~350℃, elingenakuqhathaniswa ne-SmCo5 impahla kazibuthe unomphela;

3.Izinga lokushisa le-Curie liphezulu.Iphoyinti le-Curie le-Sm2Co17 impahla licishe libe ngu-840 ~ 870 ℃, kanti iphoyinti le-Curie le-SmCo5 impahla ingu-750 ℃.Lokhu kusho ukuthi i-Sm2Co17 imelana kakhulu namazinga okushisa aphezulu kune-SmCo5.Nokho, uma kuqhathaniswa SmCo5 unomphela kazibuthe, inqubo yokukhiqiza Sm2Co17 iyinkimbinkimbi kakhulu.Ukuze kuthuthukiswe ukuphoqelelwa, kufanele kube indala izikhathi eziningi, futhi izindleko zenqubo ziphakeme kunalezo ze-SmCo5.Kuzibuthe unomphela, i-Sm2Co17 impahla kazibuthe iwuhlobo lukazibuthe oluhlala njalo olunamandla okushisa esevisi ephezulu.

Ngenxa yesidingo esandayo somazibuthe baphakade abasetshenziswa ngaphezu kuka-400 ℃ ezimbonini ze-aerospace nezimboni ze-elekthronikhi, izinto ezisetshenziswa kazibuthe ezihlala unomphela ezinezinga lokushisa eliphezulu lesevisi nokusebenza okuhle kakhulu okubanzi kwamukelekile emphakathini.Nakuba izinga lokushisa elisebenzayo likazibuthe we-Alnico unomphela lingaphezu kuka-500℃, ukuphoqelelwa kwayo kwangaphakathi kuphansi kakhulu ukuze kuhlangatshezwane nezidingo zokusetshenziswa okungokoqobo.I-NdFeb engavamile emhlabeni unomphela uzibuthe umzimba unokuphoqelela okuphezulu nokusebenza okuhle okuphelele, kodwa izinga lokushisa lokusetshenziswa alikwazi ukuhlangabezana nezidingo ezingenhla, ngenxa yokushisa okuphansi kwe-Curie kanye ne-coefficient yokushisa enkulu.Ngenxa yokusebenza kwayo okuhle kakhulu, i-Sm2Co17 impahla kazibuthe ehlala njalo isetshenziswe kakhulu emshinini, ithuluzi lokunemba, idivayisi ye-microwave, inzwa, umtshina kanye nezinye izinkambu zobuchwepheshe obuphezulu.
