AlNiCo Magnets Tsis tshua muaj ntiaj teb hlau nplaum
Samarium cobalt hlau nplaum
Lub samarium cobalt hlau nplaum yog ib hom qoob loo uas tsis tshua muaj lub ntiaj teb, uas yog tsim los ntawm samarium, cobalt thiab lwm cov ntaub ntawv tsis tshua muaj hauv av. Samarium cobalt hlau nplaum tau nyob rau plaub caug xyoo thiab nws tau siv dav, xws li siv hauv aerospace, kev tiv thaiv kev lag luam, lub cev muaj zog, hlau nplaum thiab lwm yam. Nyob rau hauv daim ntawv thov tib lub sij hawm, peb yuav tsum them nyiaj rau cov kab mob cobalt cobalt cobalt, raws li nram no:
1. SmCo hlau nplaum yog yooj yim los chais. Thaum kev soj ntsuam nrog lawv, koj yuav tsum hnav cov iav.
2. Qhov cuam tshuam ntawm cov hlau nplaum yuav ua rau cov hlau nplaum yuav raug tsoo, 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. Rau ntau tus neeg, cov hlau nplaum yog cov hlau nplaum Bale, li cas muaj samarium cobalt hlau, samarium cobalt hlau yog dab tsi? Samarium cobalt hlau nplaum, yog ib lub ntiaj teb tsis tshua muaj hlau nplaum, yog ua los ntawm samarium, cobalt thiab lwm yam khoom siv hauv ntiaj teb los ntawm qhov sib piv, yaj rau cov hlau, los ntawm crushing, siab hom, sintered tom qab cov khoom siv hlau nplaum. Nws muaj ntau lub zog, nws cov khoom sib zog ntau yam sib nqus zog (BHmax), coercivity (coercivity) thiab kub thiab stability stability thiab ntau dua NdFeB cov khoom magnet mus tas li. SmCo cov hlau nplaum muaj cov tshuaj tiv thaiv thiab oxidation tsis ua hauj lwm, samarium cobalt hlau nplaum siv ntau qhov chaw, xws li aerospace, defense and other fields.
Qhov tshwm sim sib nqus ntawm cov ntaub ntawv cob qhia cov cob coos tau muaj qhov kub ntxhov uas tshwm sim ntawm qhov ntsuas kub. Rau ferromagnetism thiab samarium cobalt magnetic tshuaj, qhov kub no tseem hu ua Curie kub; rau pyromagnetism, qhov kub thiab txias yog hu ua Neil kub. Yog li cas koj tiv thaiv cov magnetism ntawm cov hlau nplaum samarium siv? Nws yog qhov tseeb ntawm qhov kub thiab txias.
1. Txheej txheem
Feem ntau coated nrog ib co organic organic, cov roj silicone los yog ib co rwb thaiv tsev cov ntaub ntawv pov thawj. Vim yog cov ntaub ntawv uas yuav tsum tau coated nrog hnyav, qhov hnyav rau volatilize, tawm hauv ntau qhov pores ntawm txheej txheej. Qee cov txheej txheem nws yog hydrophilic, perennial, dej rau hauv infiltration, ua rau cov oxidation NdFeB damp, thiaj li hais tias nws cov kev ua tau poob.
2. Nanotechnology:
High density, cov khoom yuav luag tsis muaj channel capillary, thiab tuaj yeem ua rau cov khoom siv kev loj hlob. Yog li ntawd, nws yog qhov zoo tagnrho rau ntawm ya raws, cov txheej txheem los tiv thaiv oxidation. Hloov cov duab ntawm cov khoom loj, nrog txoj kev txheej txheem thiab plating txoj kev samarium cobalt hlau nplaum thiab NdFeB muaj zog cov khoom siv hlau nplaum muaj ib co thickness ntawm nto, nrog kev ntsuam xyuas txhua yam, xws li nrog ib txhiab daim card, koj yuav ntsuas tus ntxiv thickness ; Nanotechnology txujci, ntsuas tsis tau qhov nce ntawm qhov tuab ntawm cov khoom NdFeB. Kev ua ntawm cov khoom, kev ntseeg siab, kev pab lub neej ntev. Cov txheej txheem thiab cov khoom siv electroplating, kev siv lub sijhawm ntev, yuav tsim cov phenomenon ntawm daim tawv nqaij, qhov khoom yog raug huab cua, nws yuav ua rau cov khoom lag luam tsis zoo. Thiab nanotechnology yuav zoo heev txo cov xwm txheej ntawm qhov teeb meem no.
