Dab tsi yog qhov txawv ntawm Neodymium Iron Boron Magnets Thiab Samarium Cobalt Magnets?

Neodymium hlau boron hlau nplaum thiab samarium cobalt hlau nplaum yog cov khoom sib nqus muaj zog uas tau siv dav hauv kev lag luam, tub rog, thiab lwm yam. Txawm hais tias lawv yog cov hlau nplaum tag nrho, tseem muaj qee qhov sib txawv ntawm lawv.
Ua ntej, muaj qhov sib txawv tseem ceeb hauv cov khoom sib nqus ntawm neodymium hlau boron hlau nplaum thiab samarium cobalt hlau nplaum. Neodymium hlau boron hlau nplaum muaj cov khoom siv hluav taws xob zoo heev thiab cov hlau nplaum seem, uas tuaj yeem tsim cov hlau nplaum muaj zog heev. Yog li ntawd, lawv tau dav siv nyob rau hauv high-end motors, generators, thiab lwm yam teb. Cov khoom siv hluav taws xob sib nqus thiab cov hlau nplaum seem ntawm samarium cobalt hlau nplaum yog qis dua neodymium hlau boron hlau nplaum, tab sis lawv coercivity siab dua neodymium hlau boron hlau nplaum, yog li lawv qhov ruaj khov ntawm qhov kub thiab txias yog qhov zoo dua.
Qhov thib ob, kuj tseem muaj qee qhov sib txawv ntawm cov khoom sib xyaw ntawm neodymium hlau boron hlau nplaum thiab samarium cobalt hlau nplaum. Cov khoom tseem ceeb ntawm neodymium hlau boron hlau nplaum yog neodymium, hlau, boron, thiab lwm yam, thaum samarium cobalt hlau nplaum yog tsim los ntawm cov khoom xws li samarium thiab cobalt. Vim lawv cov khoom sib txawv, lawv kuj muaj cov yam ntxwv sib txawv hauv kev ua thiab thermal stability.
Thaum kawg, kuj tseem muaj qee tus nqi sib txawv ntawm neodymium hlau boron hlau nplaum thiab samarium cobalt hlau nplaum. Vim nws cov khoom siv hluav taws xob sib nqus ntau dua thiab kev ua kom zoo, neodymium hlau boron hlau nplaum kuj tseem kim. Samarium cobalt hlau nplaum kuj pheej yig dua.
Hauv cov ntsiab lus, neodymium hlau boron hlau nplaum thiab samarium cobalt hlau nplaum yog cov khoom siv hlau nplaum zoo heev uas tau siv dav hauv ntau daim ntawv thov. Rau cov neeg zoo tib yam, peb xav paub ntau ntxiv txog cov khawv koob thiab kev lom zem ntawm cov hlau nplaum, vam tias peb tuaj yeem nrhiav tau ntau yam nthuav dav los ntawm lub zog ntawm cov hlau nplaum.
