SmCo Magnet 1:5 yaye 2:17

Inkcazelo emfutshane:

Imagnethi yeSmCo luhlobo lwemagnethi yomhlaba enqabileyo, eyimagnethi eyenziwe ngesamarium, cobalt kunye nezinye izinto zentsimbi ezinqabileyo zomhlaba.Iphuhliswe kwi-1970, iimagnethi ze-SmCo zesibini ezinamandla, okwesibini kuphela kwi-magnets ye-NdFeB, enemveliso ephezulu yamandla (BHmax ukusuka kwi-9MGOe ukuya kwi-31 MGOe) kunye nokunyanzeliswa okuphezulu.Kukho iireyishini ezimbini zokubunjwa kweemagnethi ze-SmCo, eziyi-SmCo5 kunye ne-Sm2Co17.Umxholo we-amarium alloy malunga ne-25% -36% ngobunzima kwaye iluncedo kakhulu kwimisebenzi yokushisa okuphezulu kwaye ingasetyenziselwa izicelo eziphezulu zokushisa.Iqondo lobushushu Curie of SmCo umazibuthe yi 600-710 ℃, kwaye ubushushu ukusebenza yi 250-550℃.

Iinkcukacha zeMveliso

Iithegi zeMveliso

Ngaphandle koko, iimagnethi ze-SmCo zinezinye iimpawu:
Ukusebenza okuthembekileyo: Iimagnethi ze-SmCo zixhathisa kakhulu kwi-demagnetization zibenza zithembeke kwiindawo ezininzi.
Ukungatya kunye nokumelana ne-oxidation: Ngenxa yomxholo wentsimbi ephantsi kwizinto ezihlanganisiweyo, iimagnethi ze-SmCo zinokumelana okugqwesileyo kokutya.Ngokungafaniyo ne-NdFeB, imagnethi ye-SmCo ayifuni i-electroplating.
Uzinzo lobushushu: SmCo unako ukugcina amandla ayo magnetic kumaqondo obushushu aphezulu (249-300 ℃) kunye namaqondo aphantsi kakhulu (-232 ℃).
Izinto ezinqabileyo: Xa i-sintering, izinto eziphathekayo zinokuba brittle, ngenxa yokuba i-brittle kwaye kulula ukuyiqhekeza, ukucubungula kunemida, apho iindlela zokucubungula zendabuko zingasebenzi.Nangona kunjalo, inokucolwa, kodwa kuphela ukuba kusetyenziswe isixa esikhulu sesipholisi.Kungenxa yokuba into epholileyo inokunciphisa umngcipheko womlilo ukusuka ekuqhekekeni kwe-thermal kunye nothuli lokusila oluxutywe nge-oxidized.

Usetyenziso:
1. Iinjini ze-PM eziphezulu.Iinjini ze-PM ngokubanzi zihlala zisebenzisa iimagnethi ze-ferrite okanye imagnethi ye-NdFeB.Kodwa kwiindawo apho ubushushu budlula i-200 ℃ okanye i-torque enkulu, kuphela ii-motor SmCo PM ezinobuchule.
2. Izixhobo ze-Electroacoustic kwiinkqubo zesandisi-lizwi eziphezulu.
3. Inkqubo yesixhobo ethembekileyo kakhulu.Izixhobo ezininzi ezisetyenziswa kwi-aerospace, i-aviation, ezonyango kunye nezinye iindawo kufuneka zisebenzise iimagnethi ezisisigxina ze-SmCo ukuqinisekisa ukuthembeka okuphezulu kunye nokhuseleko olugqibeleleyo.
4. Kwi-radar ebaluleke kakhulu kunye neenkqubo zonxibelelwano, inani elikhulu leetyhubhu ezihambayo ezihambayo, iimagnetron, iityhubhu ezileqayo, ukuleqa iityhubhu zamaza, iigyrotrons kunye nezinye izixhobo zokufunxa zombane zisetyenziswa, kunye neemagnethi ze-SmCo zenza imiqadi ye-electron ecaleni kwendlela emiselweyo.
5. I-SmCo extractors magnetic kumaqula anzulu angaphantsi kwe-3000 yeemitha, kunye ne-SmCo magnetic drive (ipompo) kwindawo yobushushu obuphezulu obungama-200 ℃.
6. Intloko yokufunxa imagnethi, isahluli samagnetic, i-magnetic bearing, i-NMR, njl.
