SmCo Magnet 1:5 futhi 2:17

Incazelo emfushane:

I-SmCo uzibuthe iwuhlobo lukazibuthe womhlaba ongavamile, onguzibuthe owenziwe nge-samarium, i-cobalt nezinye izinto zensimbi ezingavamile zomhlaba.Ithuthukiswe ngo-1970, omazibuthe be-SmCo ingeyesibili enamandla, eyesibili kuphela kozibuthe be-NdFeB, enomkhiqizo omkhulu wamandla (BHmax osukela ku-9MGOe kuya ku-31 MGOe) kanye nokuphoqelela okuphezulu.Kunezilinganiso ezimbili zokwakheka kozibuthe be-SmCo, okuyi-SmCo5 ne-Sm2Co17.Okuqukethwe kwe-amarium alloy cishe ku-25% -36% ngesisindo futhi kuyasiza kakhulu ekusebenzeni okunokushisa okuphezulu futhi kungasetshenziswa ezinhlelweni zokushisa eziphezulu.Izinga lokushisa Curie of SmCo uzibuthe kuyinto 600-710 ℃, futhi izinga lokushisa ukusebenza kuyinto 250-550 ℃.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Ngaphandle kwalokho, omagnethi be-SmCo banezinye izici:
Ukusebenza okuthembekile: Ozibuthe be-SmCo bamelana ngokwedlulele nokukhishwa kazibuthe okubenza bathembeke ezindaweni eziningi.
Ukumelana nokugqwala kanye ne-oxidation: Ngenxa yokuqukethwe kwensimbi ephansi ezintweni eziyinhlanganisela, omagnethi be-SmCo banokumelana nokugqwala okuhle kakhulu.Ngokungafani ne-NdFeB, omagnethi be-SmCo abadingi i-electroplating.
Ukuqina kwezinga lokushisa: I-SmCo ingagcina amandla ayo kazibuthe emazingeni okushisa aphezulu (249-300 ℃) namazinga okushisa aphansi kakhulu (-232 ℃).
Izinto zokwakha ezinqamukayo: Lapho i-sintering, impahla ingase ibe brittle, ngenxa yokuthi i-brittle futhi kulula ukuqhekeka, ukucubungula kunemikhawulo, lapho izindlela zokucubungula zendabuko zingasebenzi.Noma kunjalo, ingagaywa, kodwa kuphela uma kusetshenziswa inani elikhulu lokupholisa.Lokho kungenxa yokuthi okokupholisa kunganciphisa ingozi yomlilo kusukela ekuqhekekeni okushisayo nothuli olugaywe nge-oxidized.

Izicelo:
1. Izinjini ze-PM ezisezingeni eliphezulu.Amamotho ajwayelekile e-PM ajwayele ukusebenzisa omagnethi be-ferrite noma omagnet be-NdFeB.Kodwa ezindaweni lapho izinga lokushisa lidlula ama-200 ℃ noma i-torque yetafula inkulu, yizinjini ze-SmCo PM kuphela ezinekhono.
2. Imishini ye-Electroacoustic kumasistimu wesipikha esikhuluma phezulu.
3. Uhlelo lwensimbi oluthembeke kakhulu.Izinsimbi eziningi ezisetshenziswa ku-aerospace, ezondiza, ezokwelashwa neminye imikhakha kumele zisebenzise omazibuthe abangapheli be-SmCo ukuze kuqinisekiswe ukwethembeka okuphezulu nokuphepha okuphelele.
4. Ezinhlelweni ze-radar nezokuxhumana ezibaluleke kakhulu, kusetshenziswa inani elikhulu lamashubhu amagagasi ahambayo, omagnetron, amashubhu ajahayo, amashubhu ajaha amagagasi, ama-gyrotron namanye amadivaysi kagesi evacuum asetshenziswa, kanti omazibuthe be-SmCo benza imishayo yama-electron ekuhambeni ngendlela enqunyiwe.
5. I-SmCo extractors kazibuthe emithonjeni ejulile engaphansi kwamamitha angu-3000, kanye ne-SmCo magnetic drive (ipompo) endaweni yokushisa ephezulu engu-200 ℃.
6. Ikhanda lokumunca kazibuthe, isihlukanisi kazibuthe, i-magnetic bearing, i-NMR, njll.
