Qhov tseeb, ob lub hlau nplaum no yog ob qho tib si neodymium hlau boron, thiab lawv txawv ntawm lawv cov txheej txheem ntau lawm. Bonded NdFeB hlau nplaum yog tiag tiag ua los ntawm kev txhaj tshuaj molding, thaum sintered NdFeB hlau nplaum yog tsim los ntawm kev siv tawm thiab cua sov rau lawv thaum kub kub. Txij li cov hlau nplaum NdFeB sib raug zoo yog txhaj tshuaj molded, lawv muaj cov nplaum thiab lawv qhov ntom yog feem ntau tsuas yog 80% ntawm qhov kev xav. Sintered NdFeB hlau nplaum tau dhau los ntawm cov txheej txheem kub-kub, yog li ntawm cov hlau nplaum, qhov attenuation ntawm bonded NdFeB hlau nplaum txheeb ze rau sintered NdFeB hlau nplaum yog li 30%.
Sintered NdFeB hlau nplaum yog anisotropic hlau nplaum tsim los ntawm hmoov sintering. Feem ntau, tsuas yog cov blanks tuaj yeem tsim los ntawm sintering, uas tom qab ntawd ua tiav rau hauv cov hlau nplaum ntawm ntau yam duab los ntawm kev siv tshuab (xws li hlau txiav, txiav, sib tsoo, thiab lwm yam). Sintered NdFeB yog cov khoom siv tawv thiab nkig uas nyuaj rau kev ua haujlwm. Nws cov txheej txheem poob yog qhov loj, tus nqi siab, qhov tseeb qhov tseeb yog qhov tsis zoo, corrosion kuj tsis zoo, thiab qhov saum npoo yuav tsum tau kho electroplating. Tab sis qhov zoo dua yog kev ua haujlwm siab, uas tau mus txog ntau dua 50M.
Bonded NdFeB hlau nplaum, tsim los ntawm Nd2Fe14B, yog cov hlau nplaum hluavtaws. Bonded NdFeB hlau nplaum yog cov hlau nplaum ua los ntawm cov hlau nplaum NdFeB sib nqus hmoov ceev ceev thiab khi los ntawm "compression molding" lossis "injection molding". Bonded NdFeB hlau nplaum muaj qhov tseeb qhov tseeb thiab tuaj yeem ua rau hauv cov khoom sib nqus nrog cov duab sib txawv. Lawv muaj cov yam ntxwv ntawm ib-lub sij hawm molding thiab multi-ncej orientation. Bonded NdFeB hlau nplaum muaj lub zog txhua yam thiab tuaj yeem tsim ib txhij nrog lwm cov kev txhawb nqa thaum molding.
Piv nrog sintered NdFeB hlau nplaum, bonded NdFeB hlau nplaum yog tsim nyob rau hauv ib kauj ruam yam tsis muaj lwm yam kev ua, thiab yuav ua tau rau hauv complex hlau nplaum ntawm ntau yam duab, uas yog unmatched los ntawm sintered hlau nplaum. Nrog kev pab los ntawm bonded NdFeB hlau nplaum, ib tug yuav txo tau qhov loj thiab hnyav ntawm motors.
