Thaum nrhiav cov hlau nplaum ruaj khov rau cov ntawv thov kev lag luam, nkag siab qhovyam tsawg ntiaj teb hlau nplaum muaj yog qhov tseem ceeb rau kev txiav txim siab yuav khoom zoo. Tsis yog txhua cov hlau nplaum ua tib yam nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, ib puag ncig ib puag ncig, lossis kev ntxhov siab ntawm txhua yam. Rau cov kws tsim khoom thiab cov tsim khoom tsim khoom, xaiv hom hlau nplaum ncaj qha cuam tshuam rau cov khoom lag luam kev ntseeg siab, tus nqi, thiab kev ua haujlwm ntev -.

Ntsiab Cai

Ob Tsev Neeg Tseem Ceeb ntawm Rare Earth Magnets

Covyam tsawg ntiaj teb hlau nplaumsiv hauv kev lag luam kev lag luam poob rau hauv ob tsev neeg tseem ceeb: Neodymium-Iron-Boron (NdFeB) hlau nplaum thiab Samarium-Cobalt (SmCo) hlau nplaum . Txawm hais tias ob qho tib si muaj cov ntsiab lus tsis tshua muaj hauv ntiaj teb, lawv muaj cov yam ntxwv sib txawv uas haum rau kev siv sib txawv.

Neodymium hlau nplaum (NdFeB)

Neodymium hlau nplaum, feem ntau hu ua NdFeB hlau nplaum, yog cov khoom lag luam muaj zog tshaj plaws uas muaj cov hlau nplaum ruaj khov. Lawv muaj feem ntau ntawm neodymium, hlau, thiab boron, nrog rau cov ntsiab lus ntxiv xws li dysprosium lossis terbium ntxiv los txhim kho qhov kub thiab txias.

Sintered NdFeB Magnets

Sintered NdFeB hlau nplaum yog tsim los ntawm cov txheej txheem hmoov metallurgy. Lawv muab cov khoom siv hluav taws xob sib nqus siab tshaj plaws ntawm txhua hom hlau nplaum, nrog cov khoom siv hluav taws xob siab tshaj plaws ntawm 30 txog 59 MGOe. Txoj kev tsim khoom muaj xws li:

• Melting thiab alloying raw khoom

• Crushing thiab milling kom zoo hmoov

•Nias hauv qhov chaw sib nqus

•Sintering ntawm qhov kub thiab txias

•Machining mus rau qhov kawg qhov ntev

• Txheej rau kev tiv thaiv corrosion

Cov hlau nplaum no tau siv dav hauv cov tsheb fais fab, cua turbines, industrial automation, thiab cov khoom siv hluav taws xob.

Bonded NdFeB Magnets

Bonded NdFeB hlau nplaum yog tsim los ntawm kev sib xyaw cov hmoov sib nqus nrog cov khoom siv polymer. Thaum lawv muab lub zog sib nqus qis dua li cov hlau nplaum sintered, lawv tuaj yeem raug molded rau hauv cov duab nyuaj thiab raug nqi ntau dua -zoo rau ntau lawm . Lawv feem ntau siv nyob rau hauv precision electronic khoom xws li headphones, sensors, thiab hard disk drives.

NdFeB Kub Qib

NdFeB hlau nplaum muaj nyob rau hauv cov qib kub sib txawv, qhia los ntawm cov ntawv txuas ntxiv:

Samarium cobalt hlau nplaum (SmCo)

Samarium cobalt hlau nplaum tau tsim nyob rau xyoo 1960 thiab tseem yog ib qho kev xaiv tseem ceeb ntawm cov hom hlau nplaum hauv ntiaj teb uas tsis tshua muaj siab rau siab - kub thiab corrosive ib puag ncig . Lawv tuaj nyob rau hauv ob lub ntsiab alloy ntau yam:

SmCo 1:5 Series

Tus thawj samarium cobalt alloy, muaj kwv yees li 37% samarium thiab 63% cobalt, muaj cov khoom siv hluav taws xob ntawm 16 thiab 22 MGOe. Cov koob no muab kev tiv thaiv corrosion zoo heev vim nws tsis muaj hlau.

SmCo 2:17 Series

Qhov ntau thiab muaj zog SmCo alloy, muaj li ntawm 25% samarium, 5% tooj liab, 18% hlau, thiab me me ntawm hafnium los yog zirconium, nrog rau cov khoom siv hluav taws xob ntawm 24 thiab 32 MGOe. Cov koob no tuaj yeem ua haujlwm ntawm qhov kub txog li 350℃thiab muaj kev tiv thaiv corrosion zoo dua piv rau NdFeB.

Muab piv rau Hom Rare Earth Magnets

Manufacturing Process Variations

Tshaj li ob tsev neeg cov khoom siv tseem ceeb, hom hlau nplaum hauv ntiaj teb tsis tshua muaj qhov sib txawv los ntawm kev tsim khoom. Sintered hlau nplaum muab qhov zoo tshaj plaws sib nqus kev ua tau zoo tab sis raug txwv nyob rau hauv cov duab complexity. Bonded hlau nplaum tso cai rau intricate geometries thiab yog haum rau siab - ntim ntau lawm, tab sis nrog txo cov hlau nplaum tso zis . Rau kev thov kev lag luam uas xav tau lub zog siab tshaj plaws thiab kev ua haujlwm zoo ib yam, sintered hlau nplaum yog qhov kev xaiv tus qauv.

Xaiv hom Txoj Cai rau Koj Daim Ntawv Thov

Xaiv qhov sib txawv yam tsawg ntiaj teb hlau nplaum nyob ntawm ntau yam:

•Ua haujlwm kubfeem ntau yog thawj qhov kev txiav txim siab. Rau cov ntawv thov siab tshaj 150 degree, SmCo hlau nplaum feem ntau nyiam, thaum NdFeB hlau nplaum muab lub zog siab dua ntawm chav tsev kub.

•Ib puag ncig tej yam kev mobkuj tseem ceeb. NdFeB hlau nplaum yuav tsum tau tiv thaiv txheej nyob rau hauv cov av ntub los yog chemically aggressive ib puag ncig, thaum SmCo hlau nplaum muaj superior corrosion kuj tsis muaj txheej.

•Nqi thiab muajcuam ​​tshuam qhov kev txiav txim thiab. NdFeB hlau nplaum yog tus nqi ntau dua - siv tau thiab dav, thaum SmCo hlau nplaum hais kom tus nqi siab dua . Rau feem ntau cov ntawv thov kev lag luam, NdFeB muab qhov zoo tshaj plaws tus nqi, nrog SmCo tseg rau tshwj xeeb siab - kub lossis lub hom phiaj- cov ntawv thov tseem ceeb .
