NdFeB Magnets:

Neodymium hlau boron, yooj yim hais, yog ib hom hlau nplaum. Tsis zoo li cov hlau nplaum peb feem ntau pom, nws yog hu ua "magneto huab tais" vim nws cov khoom sib nqus zoo heev. Neodymium hlau boron muaj ntau lub ntiaj teb tsis tshua muaj cov ntsiab lus neodymium, hlau thiab boron, uas yog tawv thiab nkig.

Vim tias qhov chaw yooj yim oxidized thiab corroded, neodymium hlau boron yuav tsum tau coated nto. Surface chemical passivation yog ib qho kev daws teeb meem zoo.

Raws li ib yam ntawm cov khoom siv hlau nplaum tsis tshua muaj hauv ntiaj teb, NdFeB muaj cov khoom siv hluav taws xob sib nqus zoo heev thiab kev sib koom tes. Nyob rau tib lub sijhawm, qhov zoo ntawm lub zog siab ntom ntom ua rau NdFeB cov khoom siv hlau nplaum ruaj khov siv dav hauv kev lag luam niaj hnub thiab cov cuab yeej siv hluav taws xob, uas ua rau nws tuaj yeem ua rau me me, sib zog thiab nyias cov twj paj nruag, electroacoustic motors, sib nqus sib nqus thiab magnetization thiab lwm yam khoom siv.

NdFeB muaj qhov zoo ntawm cov nqi siab thiab cov khoom siv kho tshuab zoo; Qhov tsis zoo yog qhov ua haujlwm kub qis, qhov ntsuas kub tsis zoo, thiab nws yooj yim rau hmoov thiab corroded. Nws yuav tsum tau txhim kho los ntawm kev kho nws cov tshuaj muaj pes tsawg leeg thiab siv txoj kev kho saum npoo kom ua tau raws li qhov yuav tsum tau ua ntawm kev siv tswv yim.
Neodymium hlau boron magnetic cov ntaub ntawv, raws li qhov tseeb tshwm sim ntawm txoj kev loj hlob ntawm lub ntiaj teb tsis tshua muaj hlau nplaum cov ntaub ntawv, yog hu ua "magneto huab tais" vim hais tias ntawm lawv zoo heev magnetic zog. Neodymium hlau boron magnetic cov ntaub ntawv yog alloys ntawm praseodymium neodymium hlau, ferroboron, thiab lwm yam. Kuj hu ua magnetic steel.
