Izinto ezilungileyo kunye nezingeloncedo ze-Sm2Co17 kunye ne-SmCo5 izixhobo ezisisigxina zemagneti

Xa kuthelekiswa ne-SmCo5, iSm2Co17inezi ncedo zilandelayo:

1. Umxholo we-cobalt kunye ne-samarium kwifomula ye-Sm2Co17 yezinto ezisisigxina zemagneti zingaphantsi kunezo ze-SmCo5 zezinto eziphathekayo ezisisigxina, ezigcina kakhulu iindleko zezinto eziluhlaza.Ngenxa yokuba i-samarium kunye ne-cobalt izinto eziluhlaza zibiza iintsimbi ezinqabileyo, ngoko ke ixabiso le-Sm2Co17 i-magnetic material esisigxina lingaphantsi kwe-SmCo5;

2. I-coefficient ye-magnetic induction yeqondo lokushisa le-Sm2Co17 ye-magnetic esisigxina malunga ne--0.02% / ℃, inokusebenza kuluhlu lwe--60 ~ 350℃, olungenakuthelekiswa ne-SmCo5 izinto ezisisigxina zemagneti;

3.Curie ubushushu buphezulu.Indawo yeCurie yezinto ze-Sm2Co17 imalunga ne-840 ~ 870 ℃, kunye ne-Curie point yezinto ze-SmCo5 yi-750 ℃.Oku kuthetha ukuba i-Sm2Co17 iyakwazi ukumelana nobushushu obuphezulu kune-SmCo5.Nangona kunjalo, xa kuthelekiswa ne-SmCo5 yezinto eziphathekayo ezisisigxina, inkqubo yokuvelisa i-Sm2Co17 inzima kakhulu.Ukuze kuphuculwe ukunyanzeliswa, kufuneka kube mdala ixesha elide, kwaye iindleko zenkqubo ziphezulu kunezo SmCo5.Kwimagnethi esisigxina, iSm2Co17 imathiriyeli kazibuthe luhlobo lwemagnethi esisigxina enobushushu benkonzo ephezulu.

Ngenxa yokunyuka kwemfuno yeemagnethi ezisisigxina ezisetyenziswe ngaphezulu kwe-400 ℃ kwimizi-mveliso ye-aerospace kunye ne-elektroniki, izixhobo zemagneti ezisisigxina ezinobushushu benkonzo ephezulu kunye nokusebenza okugqwesileyo okugqwesileyo kwamkelwe luluntu.Nangona ubushushu obusebenzayo bemagnethi esisigxina ye-Alnico ingaphezulu kwe-500 ℃, ukunyanzeliswa kwayo kwangaphakathi kuphantsi kakhulu ukuhlangabezana neemfuno zokusetyenziswa okubonakalayo.I-NdFeb enqabileyo yomhlaba osisigxina wemagnethi umzimba unokunyanzeliswa okuphezulu kunye nokusebenza kakuhle okubanzi, kodwa ubushushu bokusetyenziswa alikwazi ukuhlangabezana nezi mfuno zingasentla, ngenxa yobushushu obuphantsi beCurie kunye ne-coefficient yobushushu enkulu.Ngenxa yokusebenza kwayo okugqwesileyo, i-Sm2Co17 imathiriyeli yamagnetic esisigxina isetyenziswe ngokubanzi kwi-motor, isixhobo sokuchaneka, isixhobo se-microwave, inzwa, i-detector kunye nezinye iindawo zobuchwepheshe obuphezulu.
