Neodymium Iron Boron (NdFeB) Magnets - Tsav Tsav Tsheb Tom Qab Technology Niaj Hnub No

#NdFeB hlau nplaum yog cov hlau nplaum uas muaj zog tshaj plaws uas paub txog tib neeg. Lawv yog cov tsav tsheb tom qab ntau cov thev naus laus zis niaj hnub no thiab siv ntau yam kev siv, los ntawm cov neeg siv khoom siv hluav taws xob mus rau aerospace thiab kev tiv thaiv. Cov hlau nplaum muaj zog no tseem hu ua cov hlau nplaum hauv ntiaj teb tsis tshua muaj vim muaj cov ntsiab lus tsis tshua muaj hauv ntiaj teb, xws li neodymium thiab dysprosium, siv hauv lawv cov muaj pes tsawg leeg.

Lub zog siab ceev thiab coercivity ntawm #NdFeB hlau nplaum ua rau lawv zoo tagnrho rau ntau yam kev siv. Lawv siv nyob rau hauv motors thiab generators los hloov hluav taws xob hluav taws xob rau hauv lub tshuab hluav taws xob, hauv cov neeg siv khoom siv hluav taws xob los tsim lub suab thiab kev co, thiab hauv cov khoom siv kho mob xws li MRI cov cav tov thiab cov khoom siv kho mob implantable. Lawv kuj tau siv rau hauv kev siv dav hlau thiab kev tiv thaiv, xws li cov kev taw qhia missile thiab dav hlau tswj qhov chaw.

Kev tsim cov hlau nplaum NdFeB yog cov txheej txheem nyuaj uas muaj kev sib xyaw ntawm neodymium, hlau, thiab boron hmoov hauv ib qho piv txwv. Cov sib tov yog ces compressed rau hauv cov duab uas xav tau thiab sintered ntawm high kub los tsim ib tug ntom, khoom hlau nplaum. Lub resulting hlau nplaum yog txiav los yog hauv av mus rau qhov xav tau thiab loj.

Txawm tias muaj ntau yam zoo, NdFeB hlau nplaum kuj nthuav qhia qee qhov kev sib tw. Lawv yog cov reactive heev thiab tuaj yeem yooj yim corrode, uas tuaj yeem ua rau poob ntawm cov khoom sib nqus. Lawv kuj nkig thiab tuaj yeem tawg lossis tawg hauv kev ntxhov siab.

Raws li thev naus laus zis txuas ntxiv mus, qhov kev thov rau NdFeB hlau nplaum yuav tsum nce ntxiv, tsav kev tshawb fawb ntxiv thiab kev loj hlob hauv daim teb no. Cov kws tshawb fawb tau ua haujlwm los tsim cov txheej txheem tshiab, muaj txiaj ntsig zoo ntawm kev tsim cov hlau nplaum NdFeB uas tsis tshua muaj kev cia siab rau lub ntiaj teb tsis tshua muaj cov ntsiab lus, nrog rau kev tshawb nrhiav txoj hauv kev los txhim kho lawv cov khoom sib nqus thiab kav ntev.

Hauv kev xaus, #NdFeB hlau nplaum yog ib qho tseem ceeb hauv ntau cov thev naus laus zis niaj hnub no thiab lawv qhov tseem ceeb tsuas yog tsim kom nce ntxiv. Raws li kev tshawb fawb txuas ntxiv hauv daim teb no, peb tuaj yeem cia siab tias yuav pom kev siv tshiab tshiab rau cov hlau nplaum muaj zog no yav tom ntej.
