Dual-alloy Technology Ntawm Sintered Neodymium Magnet

Tsis tu ncua sintered neodymium hlau nplaum yog tsim los ntawm ib qho kev siv thev naus laus zis, thiab qhov ntawd txhais tau tias cov tuam txhab tsuas yog xav tau yaj ib tus tswv hlau los ntawm qhov pib. Txhawm rau txhim kho cov khoom sib nqus ntawm cov hlau nplaum, qee cov ntsiab lus tseem ceeb yuav raug ntxiv rau cov tswv alloy. Qee yam ntawm cov ntsiab lus nkag mus rau theem tseem ceeb los tswj cov khoom sib nqus ntawm lub zog sib nqus, thiab lwm cov ntsiab lus yuav tau txais kev pabcuam los txhim kho cov qauv ciam teb.

Dual-alloy thev naus laus zis yuav tsum yaj ob tus tswv alloys los ua sintered neodymium hlau nplaum. Ob tug tswv alloys sib tov ua ke raws li ib qho kev faib ua feem tom qab crushed rau hauv coarse hmoov. Yog li ua raws li dav hlau milling, nias thiab sintering.

Kev faib tawm ntawm Dual-alloy Technology

Grain ciam diffusion technology.

Tib theem tseem ceeb thiab pab theem alloy. Lub auxiliary theem alloy yuav ua hauj lwm nyob rau hauv grain ciam theem los txhim kho cov kev ua tau zoo ntawm cov hlau nplaum.

Dual lub ntsiab theem alloy. Lub ntsiab dualphase neodymium hlau nplaum muaj ob hom sib txawv ntawm cov theem tseem ceeb, suav nrog NdFeB + NdFyFeB alloy thiab NdFeB + CeFeB alloy.

NdFeB + NdDyFeB dual theem tseem ceeb alloy yog feem ntau rau kev txhim kho ntawm intrinsic coercivity, thiab NdFeB + CeFeB alloy tuaj yeem pab cerium thiab lanthanum kom ua tiav kev siv tsim nyog. Ntau cov kev tshawb fawb qhia tias NdFeB + CeFeB dual theem tseem ceeb alloy tuaj yeem txo cov nqi khoom siv thaum tseem ua haujlwm zoo sib nqus.
