Neodymium hlau nplaum, raws li ib qho ntawm cov khoom siv hlau nplaum zoo tshaj plaws nyob rau hauv cov ntsiab lus ntawm cov khoom sib nqus, tau muab faib ua ntau hom nrog cov yam ntxwv sib txawv vim qhov sib txawv ntawm cov khoom sib txawv thiab cov txheej txheem tsim khoom. Raws li cov tshuaj lom neeg muaj pes tsawg leeg thiab kev ua haujlwm tseem ceeb, kev lag luam feem ntau faib lawv ua ntau pawg loj: cov pa, siab coercivity, siab -kub resistant, thiab qis- hnyav hnyav ntiaj teb hom. Txhua pawg muaj nws tus yam ntxwv ntawm cov khoom sib nqus, yoog raws li kev thov ib puag ncig, thiab cov qauv tsim nqi, ua tau raws li qhov xav tau ntawm ntau yam xwm txheej.
Cov hlau nplaum neodymium yog raws li neodymium, hlau, thiab boron. Lawv muaj cov khoom siv hluav taws xob sib nqus siab thiab muaj qhov sib npaug ntawm qhov sib npaug thiab kev sib koom tes, ua rau lawv tsim nyog rau feem ntau cov khoom lag luam thiab cov pej xeem hauv qhov kub thiab txias, xws li motors, sensors, thiab audio devices. Cov khoom no muaj cov txheej txheem tsim khoom lag luam thiab kev ua haujlwm ruaj khov, ua rau lawv siv ntau hom kev lag luam tam sim no.
High -coercivity neodymium hlau nplaum sib txuas cov nqi tsim nyog ntawm cov khoom hnyav hauv ntiaj teb xws li dysprosium thiab terbium hauv lawv cov qauv, txhim kho cov khoom tiv thaiv rau demagnetization. Lawv muaj peev xwm tswj tau qhov sib nqus ruaj khov nyob rau hauv ib puag ncig uas muaj zog rov qab magnetic teb los yog kub hloov. Cov khoom no feem ntau yog siv nyob rau hauv siab -cov cuab yeej precision, aerospace Cheebtsam, thiab siab- kev ntseeg siab tsav cov cuab yeej, ua tau zoo nyob rau hauv siab - kub los yog muaj zog electromagnetic cuam tshuam tej yam kev mob.
High-kub resistant neodymium hlau nplaum, los ntawm kev hloov kho rau qhov sib piv ntawm alloy thiab optimization los ntawm kev kho cua sov, txhim kho Curie kub thiab thermal stability, tso cai rau ntev -lub sij hawm ua hauj lwm ntawm kub ntawm 150℃mus rau 200℃los yog ntau dua. Lawv tau dav siv nyob rau hauv tsheb cav peripheral Cheebtsam, cov khoom siv rau hauv lub tshuab soj ntsuam, thiab cov khoom siv hluav taws xob ua haujlwm nyob rau hauv siab - qhov kub thiab txias, ntsuas kev ua tau zoo thiab kav ntev.
Tsawg- hnyav tsis tshua muaj - lub ntiaj teb neodymium hlau nplaum, tsim los rau kev siv cov peev txheej ruaj khov, txo qhov hnyav tsawg- lub ntiaj teb cov ntsiab lus los ntawm cov txheej txheem xws li cov ciam teb diffusion thiab grain refinement. Qhov no tuav cov khoom sib nqus zoo thaum txo cov nqi raw khoom thiab kev cuam tshuam ib puag ncig, ua rau lawv tsim nyog rau tus nqi - cov ntawv thov kev tsim khoom loj nrog cov kev xav tau nruab nrab, xws li dav dav - lub hom phiaj motors, cov khoom siv hauv tsev, thiab qee cov khoom siv hluav taws xob.
Tsis tas li ntawd, raws li cov duab thiab cov txheej txheem ua, lawv tuaj yeem muab faib ua sintered neodymium hlau nplaum, sib txuas neodymium hlau nplaum, thiab kub- nias neodymium hlau nplaum. Sintered neodymium hlau nplaum muaj qhov ntom ntom thiab pom cov khoom sib nqus zoo; bonded neodymium hlau nplaum yog yooj yim molded rau hauv complex qauv, haum rau miniaturization thiab ntau yam designs; kub- cov hlau nplaum neodymium nias ua ke nrog cov khoom sib nqus siab nrog qee qhov kev ua kom tawv tawv, thiab feem ntau siv rau hauv cov ntawv thov nrog cov khoom siv tshwj xeeb.
Ntau hom neodymium hlau nplaum sib xyaw ua ke ntawm kev ua tau zoo, tus nqi, thiab daim ntawv thov, muab kev lag luam kev lag luam nrog cov kev xaiv yooj yim kom tau raws li ntau yam kev xav tau. Nrog rau kev txhim kho thev naus laus zis thiab kev nkag siab ntawm cov tswv yim tsim ntsuab ntsuab, ntxiv segmentation thiab kev ua kom zoo dua qub yuav ua rau muaj kev txhim kho siab -kev txhim kho zoo ntawm kev lag luam neodymium hlau nplaum.
