Cov Ntaub Ntawv Tseem Ceeb Lub Koom Haum Tsim cov cheaper 3D luam tawm hlau nplaum
3D luam ntawv yog ib yam yees siv technology uas yuav siv tau rau txhua qhov kev lag luam uas koj tuaj yeem xav txog, los ntawm cov yas yooj yim los yog hlau ntshiab. Txawm li cas los xij, cov ntaub ntawv siv los ua cov khoom tshwj xeeb xws li hluav taws xob hluav taws xob thiab cov khoom sib nqus kuj tseem muaj txoj hauv kev mus ntev. Coob tus neeg tshawb nrhiav tau tsim cov hau kev sib txawv rau cov luam hlau 3D luam. Lub koom haum tshiab tsis tshua muaj koom nrog rau daim teb no yog lub US Department of Energy cov Ntaub Ntawv Kev Tshawb Fawb Txog Kev Tshawb Fawb (CMI) siv 3D lub tshuab luam ntawv laser hlau rau optimize cov ntaub ntawv magnet. Cov khoom siv no yuav yog ib qho kev siv nyiaj qis tshaj rau cov kim qis neodymium hlau boron (NdFeB) hlau nplaum rau qee yam kev siv. Cov hlau siv hauv CMI muaj cov niobium, ib qho pheej yig thiab tsis tshua muaj tsawg lub caij hauv ntiaj teb, nrog rau cobalt, hlau thiab tooj liab. Cov kws tshawb fawb 3D luam ntau yam kev kuaj pom uas muaj ntau yam khoom xyaw.
"Qhov no yog ib qho khoom siv hlau nplaum paub, tab sis peb xav kom rov qab saib dua thiab saib seb puas yog peb tuaj yeem nrhiav tau zoo dua qhov magnetism," said CMI tus kws tshawb fawb Ryan Ott. "Nrog rau plaub lub ntsiab lus, muaj ntau txoj haujlwm los xaiv. Siv tshuab luam ntawv 3D ceev ceev ua qhov kev tshawb nrhiav. "Nws tuaj yeem siv sij hawm ntau lub lis piam los tsim cov hlau nplaum uas siv cov tshuaj ntau ntau, tab sis 3D luam ntawv tsuas siv ob xuab moos. . Cov neeg soj ntsuam tshawb pom cov qauv cia siab tshaj plaws thiab tom qab ntawd ua ob qho qauv ntawm cov qauv siv cov kev cai nrawm thiab muab coj los piv rau cov kev kuaj pom thawj zaug kom pom qhov txawv ntawm lawv.
CMI tus kws tshawb fawb Ikenna Nlebedim tau hais tias: "Vim xav tau tsim cov kev tsim nyog microstructures, kev siv laser luam los txheeb xyuas cov magnet theem ntawm cov ntaub ntawv ntau heev yog nyuaj." Tab sis qhov kev tshawb fawb no qhia tau hais tias kev tsim khoom tsim muaj peev xwm ua tau ceev kev lag luam. Ib qho cuab yeej zoo rau kev tsim cov khoom txua hluav taws xob uas ruaj khov. "
Txoj kev tshawb no tau muab teev rau hauv daim ntawv hu ua "Kev Ntsuas Xyuas Ce-Co-Fe-Cu Systems rau Daim Ntawv Sau Niaj Hnub Tag Nrho" los ntawm F. Meng, RP Chaudhary, K. Ganhda, IC Nlebedim, A. Palasyuk, E. .Simek, MJKramer thiab RTOtt. "Cov qauv ntawm tej qhov uas muaj kev tswj hwm nrog kev tswj hwm yog tsim los ntawm laser engineering mesh forming (LENS) los ntawm kev ntxiv kev sib txawv ntawm hmoov hlau mus rau ib lub pas dej ua los ntawm ib lub laser," daim ntawv qhia txog. "Raws li qhov kev ntsuam xyuas tau sib nqus ntawm LENS luam tawm, cov kab muas thiab cov hmoov nplej muaj cov ncauj lus sib txawv ntawm Fe (5-20 at.%) Thiab Co (60-45 at.%) Tau npaj tseg thaum muaj qhov Ce (16 ntawm% thiab Cu (19%) Cov ntsiab lus microstructure thiab theem evolution ntawm cov tshuaj sib txawv ntawm ntau cov tshuaj thiab lawv cov khoom nyob hauv cov khoom sib nqus tau tshawb fawb rau hauv cov ntaub ntawv pov thawj thiab cov cua kub hnyiab. Hauv LENS luam ntawv thiab kos cov qauv, peb nrhiav tau cov ntaub ntawv zoo tshaj hlau. Nyob rau hauv lub ntsiab ib theem ntawm Ce (CoFeCu) 5 microstructure, siab coercivity (HC> 10kOe) tuaj yeem ua tiav tsis muaj qhov kev txuam tawm me me. "
Lub Koom Haum Lub Ntsiab yog lub Energy Innovation Center coj los ntawm US Department of Energy lub Ames Lab, tau txais kev txhawb los ntawm Lub Tsev Tsim Kho Chaw Tsim Ua Haujlwm ntawm Chaw Ua Haujlwm Kev Txim Kho Siab thiab Lub Yuam Tsev Kev Hloov Tshiab. CMI tshawb xyuas seb yuav ua li cas txo lossis tshem tawm kev nyob ntawm lub ntiaj teb tsis tshua muaj hlau thiab lwm cov ntaub ntawv uas tseem ceeb heev rau kev siv hluav taws xob.
