Qhov kom zoo dua ntawm cov hlau nplaum neodymium yog tias lawv muaj zog sib nqus siab heev thiab quab yuam quab yuam. Piv nrog cov hlau nplaum ferrite ib txwm muaj, lawv cov hlau nplaum muaj zog ntau dua. Kev cia siab rau nws lub zog sib nqus, nws tuaj yeem muaj ntau yam kev siv, xws li ua lub luag haujlwm tseem ceeb hauv motors, generators, disk drives, thiab lwm yam. Tsis tas li ntawd, neodymium hlau nplaum muaj kev ruaj ntseg zoo heev thiab corrosion kuj thiab tuaj yeem tiv taus kub thiab tshuaj lom neeg. corrosion, uas yuav pab tau kom ntev lawv cov kev pab cuam lub neej thiab txuag cov txij nkawm thiab hloov cov nqi.
Neodymium hlau nplaum tam sim no yog cov hlau nplaum siv dav tshaj plaws thiab muaj ntau yam tshwj xeeb. Ua ntej tshaj plaws, cov hlau nplaum neodymium muaj zog sib nqus heev. Lub zog sib nqus ntawm neodymium hlau nplaum yog ntau tshaj kaum npaug ntawm cov hlau nplaum ferrite, thiab tuaj yeem ncav cuag qhov sib nqus induction ntawm 2.4 Tesla. Hauv kev siv tswv yim, lub zog sib nqus no muaj zog heev tuaj yeem ua cov hlau nplaum neodymium thawj cov khoom siv rau kev ua ntau yam sib nqus, xws li motors, generators, sensors, thiab lwm yam.
Thib ob, cov hlau nplaum neodymium muaj kev ruaj ntseg thiab corrosion kuj. Cov khoom ntawm neodymium hlau nplaum yog ruaj khov heev thiab tsis yooj yim oxidized, corroded los yog poob magnetization. Nyob rau tib lub sijhawm, cov khoom siv ntawm cov hlau nplaum neodymium kuj yog tawv heev thiab tuaj yeem tiv taus qhov cuam tshuam thiab extrusion. Qhov kev ruaj ntseg thiab toughness no yog ib qho ntawm cov laj thawj vim li cas neodymium hlau nplaum tau siv dav hauv ntau daim ntawv thov kev lag luam.
Tsis tas li ntawd, cov hlau nplaum neodymium kuj muaj cov yam ntxwv ntawm qhov me me thiab lub teeb yuag. Qhov loj thiab qhov hnyav ntawm cov hlau nplaum neodymium yog me me heev piv rau lwm cov hlau nplaum, tso cai rau cov khoom siv sib nqus me me, ua rau cov khoom siv tau yooj yim dua. Cov yam ntxwv no zoo heev rau kev siv hauv cov khoom siv hluav taws xob xws li xov tooj ntawm tes thiab khoos phis tawj, uas muaj cov kev xav tau siab heev ntawm qhov loj thiab qhov hnyav.
