Electroplating yog txheej txheem ntawm kev siv lub zog los hloov cov nickel cations rau hauv cov xim hlau nickel thiab tso nws mus rau lub anode.
1. Thickness uniformity
Uniform thickness thiab zoo plating muaj peev xwm yog cov yam ntxwv tseem ceeb ntawm electroless npib tsib xee plating, uas kuj yog ib qho laj thawj rau nws daim ntawv thov dav. Electroless npib tsib xee plating zam qhov tsis sib xws los ntawm qhov tsis sib xws tam sim no hauv txheej electroplating. Lub thickness ntawm electroplating txheej txawv heev nyob rau hauv tag nrho ib feem, tshwj xeeb tshaj yog rau qhov chaw nrog complex duab. Cov txheej yog thicker ntawm cov npoo thiab nyob ze ntawm lub anode ntawm ib feem, thaum lub txheej yog nyias nyob rau hauv lub puab nto los yog nyob deb ntawm lub anode, thiab txawm tsis tau plated. Siv electroless plating tuaj yeem zam qhov tsis txaus ntawm electroplating.
2. Tsis muaj teeb meem ntawm hydrogen embrittlement
Electroplating yog siv lub zog los hloov cov nickel cations rau hauv cov xim hlau nickel thiab tso nws rau ntawm lub anode. Cov txheej txheem ntawm kev txo cov tshuaj yog txo cov nickel cations rau hlau npib tsib xee thiab tso nws rau saum npoo ntawm cov hlau substrate. Cov kev sim tau pom tias kev suav nrog hydrogen hauv txheej txheej tsis cuam tshuam nrog cov tshuaj txo cov tshuaj tiv thaiv, tab sis yog ze ze rau cov txheej txheem electroplating. Feem ntau, cov ntsiab lus hydrogen nyob rau hauv cov txheej txheem nce nrog qhov nce ntawm qhov ceev tam sim no.
3. Kev ua haujlwm ntawm ntau cov ntaub ntawv thiab cov khoom siv, xws li corrosion resistance, high-temperature oxidation resistance, etc., yog reflected los ntawm txheej txheej ntawm cov ntaub ntawv thiab cov khoom. Feem ntau, qee cov txheej txheem nickel plated nrog cov haujlwm tshwj xeeb tuaj yeem siv los hloov cov ntaub ntawv uas tau npaj los ntawm lwm txoj hauv kev, los yog cov ntaub ntawv pheej yig substrate tuaj yeem siv los hloov cov khoom tsim los ntawm cov khoom tseem ceeb. Yog li ntawd, cov txiaj ntsig kev lag luam ntawm chemically plated npib tsib xee yog qhov tseem ceeb heev.
4. Nws tuaj yeem tso rau saum npoo ntawm ntau yam ntaub ntawv, xws li hlau npib tsib xee raws alloys, zinc raws alloys, iav, ceramics, yas, semiconductors, thiab lwm yam, tsim kom muaj kev txhim kho kev ua haujlwm ntawm cov ntaub ntawv no.
5. Nws tsis xav tau DC lub cev muaj zog lossis cov cuab yeej tswj hwm uas xav tau rau kev siv hluav taws xob dav dav, muaj kev kho cua sov tsawg, thiab tuaj yeem ua tiav qhov sib txawv corrosion thiab hnav tsis kam tom qab sib txawv rwb thaiv tsev lub sij hawm qis dua 400 degree. Yog li ntawd, nws tsis muaj teeb meem ntawm kev kho cua sov deformation, thiab tshwj xeeb tshaj yog haum rau kev ua cov khoom nrog cov duab complex thiab nto yuav tsum tau hnav thiab corrosion kuj.
6. Lub thickness ntawm cov tshuaj deposition txheej yog tswj tau, cov txheej txheem yog yooj yim, lub lag luam yog yooj yim, qhov kub thiab txias yog tsawg, thiab tus nqi qis dua lwm yam kev kho deg rau kev tiv thaiv. Nws yog tsim rau cov chaw tsim khoom me me thiab nruab nrab lossis me me.
