Muaj cov yam ntxwv ntawm stainless hlau tshuaj nickel rau hluav taws xob cua sov raj

1. Thickness uniformity

Uniform thickness thiab zoo plating muaj peev xwm yog cov yam ntxwv tseem ceeb ntawm cov tshuaj nickel plating, uas kuj yog ib qho ntawm cov laj thawj rau nws daim ntawv thov dav. Cov tshuaj nickel plating zam qhov tsis sib xws los ntawm qhov tsis sib xws tam sim no hauv cov txheej txheej electroplating. Lub thickness ntawm electroplating txheej txawv heev nyob rau hauv tag nrho ib feem, tshwj xeeb tshaj yog nyob rau hauv qhov chaw nrog complex duab. Ntawm cov npoo thiab cov ces kaum ntawm ib feem thiab nyob ze ntawm lub anode, txheej txheej yog thicker, thaum lub txheej ntawm lub puab nto los yog nyob deb ntawm lub anode yog heev nyias, los yog txawm tsis tau plated, kev siv cov tshuaj plating yuav zam qhov no deficiency. electroplating. Thaum lub sij hawm chemical plating, ntev li ntev raws li qhov saum npoo ntawm ib feem los rau hauv kev sib cuag nrog cov tshuaj plating, cov khoom siv hauv cov tshuaj plating tuaj yeem rov ua kom tiav raws sijhawm, thiab cov txheej txheej thickness ntawm ib feem yog tib yam, txawm tias cov grooves. , qhov khoob, thiab qhov muag tsis pom qhov.

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 hauv cov hlau npib tsib xee thiab tso rau saum npoo ntawm cov hlau substrate. Cov kev sim tau pom tias kev suav nrog hydrogen hauv txheej txheej tsis cuam tshuam rau cov tshuaj txo cov tshuaj tiv thaiv, tab sis yog 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.

Hauv nickel electroplating tov, tshwj tsis yog rau ib feem me me ntawm hydrogen generated los ntawm cov tshuaj tiv thaiv ntawm NiSO4 thiab H2PO3, feem ntau hydrogen yog generated los ntawm hydrolysis los ntawm electrode cov tshuaj tiv thaiv thaum ob tug ncej yog electrified. Nyob rau hauv cov tshuaj tiv thaiv anode, ib tug loj npaum li cas ntawm hydrogen yog generated, thiab cov hydrogen ntawm lub cathode thiab cov hlau Ni-P alloy precipitate nyob rau tib lub sij hawm, tsim (Ni-P) H, uas adheres rau lub deposition txheej. Vim yog qhov tsim ntawm ntau dhau ntawm atomic hydrogen ntawm lub cathode nto, ib feem desorbs los tsim H2, Txawm li cas los xij, yog tias tsis muaj sij hawm tshem tawm, nws yuav nyob hauv txheej txheej. Ib feem ntawm cov hydrogen sab laug hauv txheej txheej yuav kis mus rau hauv lub hauv paus hlau, thaum lwm feem ntawm cov hydrogen yuav sib sau ua ke ntawm qhov tsis xws ntawm cov hlau hauv paus thiab txheej los tsim cov roj hydrogen. Cov pa roj no muaj kev kub siab, thiab nyob rau hauv siab, qhov tsis xws luag yuav ua rau tawg. Nyob rau hauv kev ntxhov siab, ib qho chaw tawg yuav raug tsim, ua rau hydrogen embrittlement puas. Hydrogen tsis tsuas yog nkag mus rau hauv lub hauv paus hlau, tab sis kuj mus rau hauv lub txheej. Nws tau tshaj tawm tias electroplating npib tsib xee yuav tsum muaj qhov kub ntawm 400 degree × 8h lossis 230 degree × Tom qab 48 teev ntawm kev kho cua sov, hydrogen tuaj yeem raug tshem tawm los ntawm txheej, yog li nws nyuaj rau tshem tawm hydrogen los ntawm electroplating npib tsib xee, thaum tshuaj lom neeg nickel plating. tsis xav tau hydrogen tshem tawm.

3. Kev ua haujlwm ntawm ntau cov ntaub ntawv thiab cov khoom siv, xws li corrosion resistance thiab high-temperature oxidation resistance, 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, lossis cov khoom siv hluav taws xob pheej yig 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 tas yuav tsum muaj DC lub cev muaj zog lossis cov khoom siv tswj kev xav tau rau kev siv hluav taws xob dav dav, thiab kev kho cua sov yog tsawg. Ntev npaum li nws dhau lub sijhawm rwb thaiv tsev sib txawv hauv qab 400 degree, sib txawv corrosion kuj thiab hnav tsis kam. 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 controllable, nrog rau cov txheej txheem yooj yim, yooj yim ua hauj lwm, tsis tshua muaj kub, thiab tus nqi qis dua piv rau lwm yam kev tiv thaiv nto. Nws yog tsim rau cov chaw tsim khoom me me thiab nruab nrab lossis me me.
