Sintered NdFeB hlau nplaum, piv txwv li sintered neodymium hlau boron hlau nplaum, yog cov khoom siv hlau nplaum ruaj khov raws li Nd-Fe-B tetragonal siv lead ua qauv. Sintered NdFeB hlau nplaum yog tsim los ntawm M. Sagawa pab neeg nyob rau hauv thaum ntxov 1980s, lawv yog tsim los ntawm ib tug hmoov metallurgy txheej txheem.
Sintered NdFeB hlau nplaum muaj peb yam tseem ceeb neodymium, hlau thiab boron. Lub caij neodymium tuaj yeem hloov tau los ntawm ib feem ntawm lwm yam tsis tshua muaj hauv ntiaj teb xws li praseodymium, dysprosium, terbium, cerium, thiab lwm yam. Cov khoom hlau tuaj yeem hloov tau los ntawm ib feem ntawm cobalt caij kom cov hlau nplaum 'Curie kub Tc, thermal stability thiab corrosion. tsis kam. Txhawm rau tswj cov microstructure thiab microchemistry kom ua tau raws li qhov yuav tsum tau ua, nws kuj ntxiv qee cov khoom siv doping xws li txhuas, tooj liab, niobium, gallium, thiab lwm yam. Rau kev cai NdFeB hlau nplaum sintered, tswj cov qauv yog txoj hauv kev kom tau txais cov hlau nplaum uas yuav tsum tau muaj. qib.
Vim lawv cov khoom sib nqus zoo heev (high remanence Br 1.1-1.5 T, nruab nrab siab coercivity Hcj 800-3000 kA/m^3 thiab siab tshaj plaws zog khoom (BH) max 220-430 kJ / m^3) ua ke nrog cov nqi sib tw, sintered NdFeB hlau nplaum yog dav siv hauv DC motors, servo motors, stepper / stepping motors, synchronous motors, linear motors, suab coil motors (VCMs), cua turbines thiab generators, magnetic resonance imaging ( MRI), hluav taws xob fais fab kauj (EPS), sib nqus sib nqus, thiab lwm yam.
