Cov tshuaj tiv thaiv technology ntawmNdfeb Neodymium MagnetFeem ntau suav nrog electroplating thiab electroless plating ntawm cov hlau txheej, kev hloov zaj duab xis ntawm ceramic coatings thiab txau thiab electrophoresis ntawm cov organic coatings.Hauv kev tsim khoom, feem ntau yog siv los npaj cov hlau tiv thaiv txheej rau saum npoo ntawm NdFeb hlau nplaum los ntawm cov txheej txheem electroplating.Electroplating yog txheej txheem uas cov hlau nplaum ua haujlwm yog siv los ua cov cathode thiab cov hlau cation hauv cov tshuaj electroplating yog txo rau saum npoo ntawm cov hlau nplaum los ntawm kev siv cov hluav taws xob sab nraud los tsim cov hlau txheej.Kev tiv thaiv electroplating ntawmSintered Neodymium Magnetsyog tsuas yog los txhim kho corrosion kuj ntawm cov hlau nplaum, nrog rau txhim kho cov khoom siv kho kom zoo nkauj thiab kho kom zoo nkauj.
Tom qab ntau xyoo ntawm kev tsim thiab siv, qhov tsis xws luag ntawm NdFeb hlau nplaum electroplating tiv thaiv txheej kuj tseem pom tseeb: Lub porosity ntawm txheej yog loj, txheej tsis ntom, thiab nws muaj qhov ua siab ntev.Lub ces kaum ntawm lub workpiece yuav thickened vim lub concentration ntawm lub hwj chim kab nyob rau hauv cov txheej txheem electroplating, yog li lub ces kaum ntawm lubRare Earth Permanent Magnetyuav tsum tau chamfered, thiab qhov sib sib zog nqus qhov qauv tsis tuaj yeem plated.Electroplating txheej txheem muaj kev puas tsuaj rau cov hlau nplaum matrix.Hauv qee lub sijhawm hnyav, tom qab siv cov txheej txheem electroplating rau lub sijhawm ntev, cov txheej txheem yuav tshwm sim tawg, tev tawm, yooj yim poob thiab lwm yam teeb meem, thiab kev tiv thaiv kev ua haujlwm yuav txo qis.Nrog rau kev txhim kho ntawm ib puag ncig kev paub, qhov kev faib ua feem ntawm tag nrho cov nqi ntawm electroplating peb pov tseg kev kho mob nce sharply.
Neodymium electromagnetnickel plating tshuab yog hais txog REDOX cov tshuaj tiv thaiv ntawm cov hlau ntsev thiab txo tus neeg sawv cev hauv chav da dej yam tsis muaj qhov sib ntxiv ntawm cov ntawv thov tam sim no.Nyob rau hauv qhov kev txiav txim catalytic ntawm lub workpiece nto, cov txheej txheem ntawm hlau ion txo deposition.Piv nrog electroplating, cov txheej txheem electroless plating yog qhov yooj yim, tsis xav tau lub zog thiab cov khoom siv hluav taws xob, txheej tuab yog zoo ib yam, tshwj xeeb tshaj yog tsim rau cov duab ntawm cov khoom ua haujlwm nyuaj, qhov sib sib zog nqus qhov, cov yeeb nkab sab hauv phab ntsa plating, qhov ntom thiab hardness ntawm txheej. yog siab dua.Electroless plating kuj muaj qee qhov tsis txaus, txheej txheej thickness tsis nce, tuaj yeem plated ntau yam tsis muaj ntau, cov txheej txheem yuav tsum muaj siab, kev tu da dej yog ntau txoj hauv kev.Chemical plating feem ntau yog npib tsib xee plating, tooj liab plating thiab nyiaj plating.
Tsis tas li ntawd, cov txheej txheem ntawmSintered Neodymium Magnetsyog nquag rau micro qhov, xoob qauv, ntxhib nto thiab lwm yam tsis xws luag, thiab NdFeb mus tas li hlau nplaum nyob rau hauv daim ntawv thov ntawm qhov chaw ua hauj lwm yog feem ntau kub, high humidity.Cov teeb meem no muab cov kev mob yooj yim rau NdFeb hlau nplaum corrosion nyob rau hauv qhov kub thiab txias ib puag ncig.Nyob rau tib lub sijhawm, cov txheej txheem tsim khoom ntawm NdFeB yog ib qho yooj yim kom muaj O, H, Cl thiab lwm yam impurities thiab lawv cov tebchaw, cov nyhuv corrosive yog O thiab Cl cov ntsiab lus, hlau nplaum thiab O oxidation corrosion, thiab Cl thiab nws cov tebchaw yuav ua kom cov oxidation. txheej txheem ntawm cov hlau nplaum.Cov laj thawj rau qhov yooj yim corrosion ntawm NdFeb hlau nplaum feem ntau yog vim li no: ib puag ncig ua haujlwm, cov khoom siv thiab cov tshuab tsim khoom.Kev tshawb fawb qhia tau hais tias qhov corrosion ntawm NdFeB hlau nplaum feem ntau tshwm sim nyob rau hauv peb qhov chaw hauv qab no: ib puag ncig sov thiab ntub, ib puag ncig electrochemical, lub sijhawm ntev kub kub ib puag ncig hauv qhov chaw qhuav, thaum kub qis dua 150 ℃, oxidation tus nqi ntawm NdFeb hlau nplaum yog heev. qeeb.
