Basic formula ntawm electroplating tov rau hluav taws xob cua sov raj

Tus nqi deposition tsis tsuas yog qhia txog cov txheej txheem dynamic ntawm cov tshuaj deposition, tab sis kuj ncaj qha cuam tshuam rau kev ua tau zoo thiab zoo ntawm txheej [31]. Vim yog qhov nyuaj ntawm kev hloov pauv hauv cov khoom sib xyaw thiab cov txheej txheem plating tsis tau ntawm cov tshuaj deposition C-raws li alloy plating tov, nws cov deposition tus nqi yog cuam tshuam los ntawm ntau yam. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua qhov kev tshawb fawb tob txog cov tshuaj chemical deposition npaum li cas.

Basic formula ntawm plating tov

Cov qauv yooj yim ntawm cov tshuaj plating [s] yog: COC12.6H2011.7g/L; NiCl2 · 6H205.0g/L; NaBH, 0.6g/L; Na2C, H, O, · 2H2{{20}}65.0g/L; NH4CI 12.0g/L; ethylenediamine 1.2g / L; stabilizer 1.0g / L; 6600 C; pH13^14; Chaw thau khoom muaj peev xwm 0.8dm2 / L; Cov ntsiab lus tsis tshua muaj hauv ntiaj teb tau ntxiv rau hauv daim ntawv ntawm chlorides.

1.2 Cov txheej txheem sim

Cov qauv yog 20mm x 10mm x 0.03mm tooj liab ntawv. Vim qhov tsis muaj peev xwm ntawm tooj liab los ntawm kev pib plating, nws yog qhov tsim nyog los qhia plating. Thaum lub alloy pib deposit, nws spontaneously mus. Lub AS10200ADT ultrasonic generator siv (280W, 40 / 60kHz) muaj ob zaus: 40kHz thiab 60kHz, thiab lub zog tuaj yeem hloov kho ntawm 400o thiab 90 feem pua ​​​​ntawm lub zog siab tshaj plaws; Lub sij hawm plating yog 30 feeb; Lub FA2004N hluav taws xob analytical tshuav nyiaj li cas yog siv los xam tus nqi deposition ntawm tus qauv los ntawm qhov hnyav.

Raws li cov tshuaj deposition ntawm Co Ni B alloy, lub ntiaj teb tsis tshua muaj cov ntsiab lus tau ntxiv los npaj lub tais uas muaj txheej nrog cov khoom sib nqus zoo. Kev cuam tshuam ntawm lub ntiaj teb tsis tshua muaj cov ntsiab lus ntawm cov qauv thiab cov khoom ntawm txheej tau kawm. Kev tshawb fawb qhia tias txawm hais tias cov electrode muaj peev xwm ntawm lub ntiaj teb tsis tshua muaj cov ntsiab lus tsis zoo, lawv nyuaj rau ncaj qha los ntawm cov kev daws teeb meem aqueous. Txawm li cas los xij, nyob rau hauv induction ntawm tsim nyog complexing neeg ua hauj lwm thiab kev hloov pab pawg neeg cov ntsiab lus, lub electrode muaj peev xwm ntawm tsawg lub ntiaj teb hlau yuav ua tau zoo hloov, thaum lub electrode muaj peev xwm ntawm kev hloov pab pawg hlau tuaj yeem ua rau tsis zoo, yog li txhawb lawv cov electrode muaj peev xwm mus kom ze thiab ua tiav kev txo qis. deposition ntawm kev hloov pab pawg hlau thiab tsawg ntiaj teb hlau.
