Dhau li ntawd, SmCo hlau nplaum muaj lwm yam nta:
Txhim khu kev ua tau zoo: SmCo hlau nplaum tsis tshua muaj zog rau demagnetization ua rau lawv txhim khu kev qha hauv ntau qhov chaw.
Corrosion thiab oxidation tsis kam: Vim muaj cov ntsiab lus hlau tsawg hauv cov khoom sib xyaw, SmCo hlau nplaum muaj kev tiv thaiv zoo heev.Tsis zoo li NdFeB, SmCo hlau nplaum tsis xav tau electroplating.
Kev ruaj ntseg kub: SmCo tuaj yeem ua kom nws lub zog sib nqus ntawm qhov kub thiab txias (249-300 ℃) thiab kub tsis tshua muaj (-232 ℃).
Brittle cov ntaub ntawv: Thaum nyob rau hauv sintering, cov khoom tej zaum yuav nkig, vim nws yog nkig thiab yooj yim rau tawg, kev ua muaj kev txwv, uas cov tsoos txheej txheem yog tsis ua hauj lwm.Txawm li cas los xij, nws tuaj yeem ua tau hauv av, tab sis tsuas yog siv ntau npaum li cas ntawm cov coolant.Tias yog vim li cas lub coolant tuaj yeem txo qhov kev pheej hmoo ntawm hluav taws kub los ntawm thermal tawg thiab oxidized sib tsoo plua plav.
Daim ntawv thov:
1. High-end PM motors.General PM motors feem ntau siv cov hlau nplaum ferrite lossis NdFeB hlau nplaum.Tab sis nyob rau hauv qhov chaw uas qhov kub thiab txias tshaj 200 ℃ los yog lub tsev torque loj, tsuas yog SmCo PM motors muaj peev xwm.
2. Cov khoom siv hluav taws xob hauv cov tshuab ua suab nrov nrov.
3. Cov cuab yeej siv tau zoo heev.Ntau cov cuab yeej siv hauv aerospace, aviation, kev kho mob thiab lwm yam kev lag luam yuav tsum siv cov hlau nplaum ruaj khov SmCo kom ntseeg tau tias muaj kev ntseeg siab thiab zoo meej.
4. Nyob rau hauv cov radar thiab kev sib txuas lus tseem ceeb heev, muaj coob tus neeg mus ncig yoj raj, magnetrons, chasing tubes, chasing yoj raj, gyrotrons thiab lwm yam hluav taws xob nqus cov cuab yeej siv, thiab SmCo hlau nplaum ua electron beams nyob rau hauv lub tsiv raws txoj kev.
5. SmCo magnetic extractors nyob rau hauv qhov tob tob hauv qab 3000 meters, thiab SmCo magnetic tsav (tswj) nyob rau hauv kub kub ib puag ncig ntawm 200 ℃.
6. Sib nqus nqus taub hau, sib nqus sib nqus, sib nqus bearing, NMR, thiab lwm yam.
