Xinfeng hlau nplaum nrhiav txoj hauv kev tshiab los txhim kho magnetic coercivity thiab Curie kub

Xinfeng hlau nplaum pom nyob rau hauv lub chav kuaj, lubrare ntiaj teb hlau nplaumalloy hlau nplaum feem ntau tuaj yeem cuam tshuam los ntawm ntau yam, ntau xyoo tau sim, kev tshawb fawb thiab kev loj hlob mus rau ib lub tshuab tshiab los txhim kho lubNdFeb cov hlau nplaum ruaj khovcoercive quab yuam thiab Curie kub, yog li ntawd los txhim kho stability ntawm muaj zog NdFeb tsis tshua muaj lub ntiaj teb hlau nplaum nyob rau hauv ib txwm kub los yog kub kub, qhov kev ua tau zoo hloov dua siab tshiab rau lub zog NdFeb hlau nplaum kev lag luam muaj qhov tseem ceeb heev.Muaj ob txoj hauv kev los kawm txog kev txhim kho kev coercivity ntawm lub ntiaj teb tsis tshua muaj cov hlau nplaum ruaj khov: ib qho yog txhawm rau nrhiav kev sib raug zoo ntawm kev coercivity thiab lub cev los yog geometric tsis nyob rau theem alloy raws li ib qho qauv ntawm lub cev thiab los ntawm kev kho lej tsim nyog.Lwm tus tuaj yeem saib ncaj qha kev sib raug zoo ntawm microstructure ntawm cov hlau los yog cov theem tsis thiab coercivity los ntawm kev sim.

Xinfeng magnet tuam txhab pom tias cobalt, txhuas nrog kev siv neodymium hlau boron alloy, ntxiv 10% cobalt, alloy coercivity ncov ntawm 4% txhuas;Thaum ntxiv 16% cobalt, lub ncov coercivity ntawm cov hlau yog 2% txhuas.Qhov sib ntxiv ntawm aluminium tsub kom lub coercivity ntawm cov alloy thiab cobalt tsub kom Curie kub ntawm cov alloy.Kev sib xyaw ua ke ntawm ob, ob qho tib si txhim kho neodymium hlau boron coercivity, thiab tuaj yeem txhim kho Curie kub ntawm Neodymium hlau boron.Xinfeng kuj pom tias yog ntxiv qhov tsim nyog ntawm niobium, Neodymium hlau boronhlau nplaum ruaj khovalloy tuaj yeem txhim kho qhov kub ntawm Curie tib lub sijhawm, kev sib koom ua ke yuav zoo heev.Kev tshoov siab los ntawm kev sim cov txiaj ntsig, Xinfeng yuav txuas ntxiv kawm txog kev ruaj ntseg sib nqus ntawm lub ntiaj teb tsis tshua muaj hlau nplaum ruaj khov, thiab vam tias yuav siv nws rau kev tsim kho tshiab ntawm cov txheej txheem tsim khoom, kev tsim cov khoom sib nqus thiab kev tsim khoom sai li sai tau, txhawm rau txhim kho qhov zoo. ntawm cov khoom thiab txhim kho cov kev sib tw tseem ceeb ntawm Xinfeng cov khoom.
