NdFeB hlau nplaum, raws li lub cim hlau thib peb ntawm lub ntiaj teb tsis muaj zog thiab siv cov nqi ntau yam thiab cov nqi tsim nyog. Tsis tshua muaj cov hlau nplaum ruaj khov cov khoom siv tsis muaj zog yog ua los ntawm cov khoom siv tsis tshua muaj feem thiab kev hloov pauv ntawm cov txheej txheem tshwj xeeb. Lawv muaj cov siab magnetocrystalline anisotropy thiab siab saturation magnetization. Lawv yog ib qho ntawm cov khoom siv hlau nplaum ruaj khov nrog cov khoom sib nqus uas zoo tshaj plaws Tshwj xeeb, ndfeb cov khoom lag luam ruaj khov raws li cov intermetallic sib xyaw ND2FE144B tau ntau zuj zus hauv kev lag luam tawm ntawm kev lag luam vim lawv cov khoom lag luam loj heev thiab lub zog quab yuam.
Kev tsim cov khoom lag luam ndfeb tuaj yeem muab faib ua sintering, kev sib koom tes, kub nias, thiab lwm hom raws li cov txheej txheem sib txawv. Ntawm lawv, sintered ndfeb tau dhau los ua cov kev xaiv tseem ceeb hauv kev ua lag luam vim nws qhov kev ua tau zoo thiab muaj nqi ntau-ua hauj lwm zoo. Raws li lub ntiaj teb xav tau rau cov khoom lag luam sib nqus ntawm cov khoom siv sib nqus hauv tsev, drones-txuag hluav taws xob hauv tsev, cua tshuab hluav taws xob, thiab lwm thaj teb tau nrawm nrawm.
Cov ncauj lus kom ntxaws piav qhia ntawm cov txheej txheem tsim khoom
1. Cov khoom siv cov khoom siv thiab smelting
Kev tsim khoom ntawm NDFEB hlau nplaum pib nrog cov khoom siv raw. Lub ntiaj teb tsis tshua muaj neeg neodymium, hlau, thiab boron yog lub ntsiab lus tseem ceeb, thiab me me ntawm dysprosium, thiab me me, tooj liab, thiab lwm cov ntsiab lus yuav raug ntxiv rau kev ua kom ua tiav. Cov ntaub ntawv no tau yoog nyob rau hauv lub rauv taws kub nyob rau hauv lub tshuab cua tshuab siab lossis tiv thaiv huab cua los ua ib qho tsis zoo li qub ingot. Tus txheej txheem no yuav tsum tau tswj hwm cov huab cua ntau yam thiab cov ntaub ntawv kub kom tsis txhob muaj kev sib txuam ntawm cov khoom tsis sib xws thiab cov oxidation ntawm cov khoom.
2. Hmoov tau hmoov
Cov alloy Ingoots yauv ntau dua cov kev kho mob txias thiab kho cua sov, ua raws li los ntawm hydrogen crushing kom hloov cov chunks loj ntawm cov hmoov zoo. Kauj ruam no yog qhov tseem ceeb rau qhov me me, cov duab, thiab kev sib xws ntawm cov hmoov. Thaum lub sij hawm cov hmoov nplej hmoov, cov ntsiab lus pa ntawm cov hmoov yuav tsum tau nruj me ntsis tswj hwm kom tiv thaiv cov oxidation ntawm lub ntiaj teb tsawg.
3. Kev tsim thiab sib nqus
Cov hmoov tau thauj khoom mus rau hauv lub stamping tuag, taw qhia thiab tau tsim nyob rau hauv lub cev sib nqus, thiab tom qab ntawd tsim rau hauv lub cev sib nqus los ntawm kev molding lossis khaub thuas yog tshuab raj tshuab hluav taws xob. Cov kauj ruam no txiav txim siab lub microstructure thiab kev taw qhia ntawm cov hlau nplaum thiab muaj qhov cuam tshuam tseem ceeb ntawm qhov kawg sib nqus cov khoom sib nqus.
4. Sintering thiab Tempering
Sintering yog ib kauj ruam tseem ceeb hauv kev txhim kho cov hluav taws xob ceev thiab cov khoom sib nqus. Thaum kub siab, hmoov particles diffuse thiab muab sib tov los ua cov hlau tuab. Tom qab sintering, cov hlau nplaum feem ntau yauv mus rau qhov ua kom zoo dua ntawm lawv cov microstructure rau kev ua kom zoo tshaj plaws cov khoom sib nqus.
5. Ua Txhua Yam
Cov hlau nplaum sintered yog machined raws li kev thov, suav nrog txiav, thiab lwm yam kom ua tiav qhov loj me thiab cov duab. Tev yuav tsum tau nruj me ntsis tswj tau thaum ua kom muaj kev sib xws thiab kev ntseeg tau ntawm cov hlau nplaum.
6. Nto Kho thiab Plating
Txij li ndfeb hlau nplaum yog rhiab rau corrosion, kev kho deg yog qhov tseem ceeb. Cov kev kho mob ib txwm muaj xws li galvanizing, thiab electrophoretic txheej los muab ib txheej ntxiv ntawm kev tiv thaiv thiab txhim kho cov tsos ntawm cov hlau nplaum. Cov txheej txheem electroplating yuav tsum tau kho kom meej ntawm cov kev sib xyaw ntawm cov kev daws teeb meem thiab plating cov kev sib txuam thiab cov khoom sib xyaw ntawm cov txheej.
7. Kev Soj Ntsuam Zoo thiab Kev Ntsuam Xyuas Kev Ua Tau Zoo
Thaum kawg, txhua lub Magnet yuav tsum tau raug tsim kho kom zoo, thiab lwm yam kev soj ntsuam kev ntsuas ntsuas, sib nqus, thiab siab kawg ntawm kev sib nqus khoom. Ib qho ntxiv, nws yog qhov ua tau rau kev ua tau kev ntsuas ua tau raws cov chaw tshwj xeeb, xws li cov cua sib nqus hauv qab kub, qis kub, lossis cov av noo huab cua.
Los ntawm cov txheej txheem txheej txheem saum toj no, NDFEtable tuaj yeem ncav cuag cov qauv kev ua tau zoo thiab ua kom tau raws li cov ntaub ntawv nruj ntawm kev lag luam niaj hnub no. Txhua yam hauv cov txheej txheem tsim khoom muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov khoom kawg, yog li cov yaum sij kom nruj yog cov yuam sij zoo tshaj plaws.
