Samarium Cobalt Magnets Kev ruaj ntseg loj
Qhov kev ruaj ntseg editor
1. SmCo hlau nplaum yog ib qho yooj yim rau tev. Thaum kev soj ntsuam nrog lawv, koj yuav tsum hnav cov iav.
2. Muab cov hlau nplaum sib dhos ua ke yuav ua rau cov hlau nplaum nplawm, uas ua rau muaj kev phom sij.
3. SmCo yog tsim los ntawm cov txheej txheem sintering, thiab tag nrho cov ntaub ntawv sintered thiab muaj feem ntau yuav tsim cov kab nrib sab hauv. Lub hlau nplaum tsis muaj qhov sib xyaw kom zoo nkauj thiab tsuas yog muaj nuj nqi ntawm kev npaj hlau magnetic. Yog li ntawd, nws yog tsim nyog los tsim ib qho kev kho tshwj xeeb ntawm txhua tus neeg los muab tag nrho lub cev txaus txhua yam kev cia siab.
Ntau lawm thiab ua editor
Samarium cobalt magnet ntau txheej txheem: cov khoom xyaw → melting ingot → milling → siab → sintering tempering paub → sib nqus detection paub → sib tsoo ua tiav → txiav → cov khoom tiav.
Cov kev sib txuam no feem ntau yog ua tiav hauv ib lub xeev uas tsis yog-ntuav. Txiav nrog nplua nplua (dej-txias) thiab cov pob zeb diamond. Cov txheej txheem no yog xav tau yog tias qhov drilling qhov los yog lwm yam nta. Qhov sib tsoo ntawm qhov sib tsoo yuav tsum tsis txhob qhuav, vim hais tias tus kabcov cobalt muaj ib qho kev sib tsoo tsawg. Ib lub txim taws me me, xws li cov hluav taws xob muaj zog, muaj peev xwm kub hnyiab. Qhov kub ntawm qhov hluav taws kub yuav kub thiab nyuaj los tswj.

2012 Nyiv lub tuam txhab Toshiba tsim muaj lub siab ceev cav nrog samarium cobalt hlau nplaum, qhov no magnet tsis muaj tag nrho cov khoom tsis tshua muaj dysprosium, tab sis qhov sib zog nqus dag zog yog tam sim no dav siv tshaj li cov hlau nplaum uas tsis muaj zog neodymium.
Tus tshiab tsim high-hlau concentration of samarium cobalt hlau nplaum uas siv Toshiba txoj kev tshawb nrhiav kev lag luam thiab kev tsim kho thev naus laus zis, yog li ntawd cov hluav taws xob uas muaj hlau nplaum li ntawm 100 degrees Celsius nyob rau hauv lub cheeb tsam muaj cua daj cua dub uas tsis muaj zog neodymium hlau nplaum muaj zog quab yuam. Yuav ua kom cov hlau nplaum dag ntxiv, R cov neeg ua hauj lwm yuav yog hlau los ntawm thawj 15% mus rau 20% mus rau 25%, thiab hauv kev sintering ntawm kub, lub sij hawm, siab mus cuag qhov zoo tshaj plaws kev mob, ua li cas txo cov hlau tsis sib haum nce qhov oxidation Thiab lwm yam. Npaj muab cov paj ntoo tshiab no tso rau hauv kev ua lag luam los ntawm xyoo 2012.
Samarium cobalt hlau nplaum (2:17) thiab NdFeB hlau nplaum:
(1) Cov khoom xyaw: NdFeB Hlau: Tsis tshua muaj hlau lub cev hlau 29% -32.5% Hlau hlau hlau 63.95-68.65% Cov khoom ntim tsis muaj pliag 1.1-1.2% Ntxiv me me ntawm dysprosium 0.6-1.2% Niobium 0.3-0.5% Aluminium 0.3-0.5 % Copper 0.05-0.15% thiab lwm yam ntsiab lus.
Samarium cobalt hlau nplaum 2:17: tsis tshua muaj av hlau samarium Sm: 23-28% lub ntiaj teb tsis tshua muaj hlau cobalt Co: 48-52% hlau hlau hlau Fe: 14-17% hlau tooj tooj liab Cu: 5-7% ib tug me me ntawm zirconium Zr: 2- 3 (2) kev ua tau zoo kuj txawv txav, qhov kev ua tiav ntawm kev siv tshuaj samarium cobalt magnet dua NdFeB tsis muaj zog!
Qhov yooj yim tshaj plaws los ntawm kev pom los ntawm cov tsos ntawm ferrite xoob thiab tsis muaj metallic luster, samarium cobalt muaj ib lo lus sib dhos thiab ntom, neodymium hlau boron yeej muaj ib txheej electroplated los yog nws yog ib qho yooj yim xeb. Tab sis cov saum toj no yog rau cov kws kho mob thiab tsis muaj cov khoom siv, txoj kev xav ntawm tus sau los yog thawj kab ntawm txoj kev yooj yim tshaj plaws, kev siv xwb.
