NdFeB hlau nplaum, raws li ib qho tseem ceeb sib nqus tivthaiv hauv kev lag luam niaj hnub no, nyiam ntau daim ntawv thov nrog lawv lub zog sib nqus. Hauv ntau cov khoom siv hlau nplaum NdFeB, raws li qhov sib txawv ntawm kev tsim khoom thiab cov yam ntxwv ntawm lub cev, peb tuaj yeem faib lawv mus rau ntau pawg.
Ua ntej tshaj plaws, los ntawm qhov pom ntawm cov txheej txheem tsim, NdFeB hlau nplaum tuaj yeem muab faib ua ntau hom xws li sintering, kev sib txuas thiab kev txhaj tshuaj molding. Sintered NdFeB hlau nplaum yog tsim los ntawm sintering hmoov tsis tshua muaj lub ntiaj teb hlau nrog hlau-raws li alloys ntawm qhov kub thiab txias, uas muaj peev xwm tsim cov khoom uas muaj siab ceev thiab zoo uniformity. Hom kev sib txuas yog tsim cov duab uas xav tau los ntawm kev sib txuas cov granular lossis cov ntaub ntawv ua ke los ntawm cov nplaum, thiab tom qab ntawd kho kom tau cov khoom tiav. Tsis tas li ntawd, kev txhaj tshuaj molding NdFeB hlau nplaum siv kev txhaj tshuaj molding tshuab, ua rau cov qauv sab hauv thiab sab nraud ntawm cov khoom siv ntau dua thiab zoo.
Thib ob, raws li qhov ntsuas kev ua tau zoo sib txawv thiab daim ntawv thov scenarios, peb tuaj yeem sib txawv ntxiv rau hom NdFeB hlau nplaum. Piv txwv li, raws li lawv cov remanent magnetization, lawv tuaj yeem muab faib ua qib zoo tib yam, qib siab remanent thiab ultra-high remanent qib khoom. Ntawm lawv, qib zoo tib yam NdFeB hlau nplaum yog tsim rau lub sijhawm uas tsis tshua muaj hlau nplaum uas yuav tsum tau muaj, xws li qee qhov yooj yim electromagnets lossis tsav hlau nplaum hauv cov hais lus nrov. Cov qib siab remanent NdFeB hlau nplaum muaj qhov me me thiab qhov hnyav thaum tuav lub zog txaus, uas yog qhov tsim nyog siv rau hauv cov khoom siv uas xav tau lub teeb yuag thiab compact, xws li cov hlau nplaum me me hauv lub lens motor ntawm lub koob yees duab xov tooj ntawm tes. Raws li rau qib ultra-high remanent qib NdFeB hlau nplaum, nws ua tiav qhov zoo tshaj plaws kub ruaj khov thiab cov lus teb cov yam ntxwv ntawm lub hauv paus ntawm kev ua kom muaj zog sib nqus sib nqus, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv high-tech xws li radar systems.
Tsis tas li ntawd, nyob rau hauv kev pom ntawm qhov yuav tsum tau ntawm sab nraud kev cuam tshuam tsis kam, NdFeB hlau nplaum kuj tuaj yeem muab faib ua ntau qib ntawm cov khoom xws li qib siab coercivity thiab qib coercivity qis. High coercive Nd-Fe-B hlau nplaum tuaj yeem tiv thaiv kev cuam tshuam sab nraud kom ntseeg tau tias kev ua haujlwm ntawm cov cuab yeej tsis cuam tshuam; Txawm hais tias qhov qis qis qis ntawm NdFeB hlau nplaum muaj qhov zoo ntawm qhov hnyav dua thiab ntim me me, lawv yuav ua rau me ntsis qis dua ntawm kev cuam tshuam los ntawm kev cuam tshuam, thiab tsim nyog siv rau cov sijhawm uas cuam tshuam sab nraud tsis yog qhov tshwj xeeb.
