Electroplating hluav taws xob cua sov tube lub zog tus neeg sawv cev

Nyob rau hauv lub ci nickel-hlau alloy plating tov, lub zog tus neeg sawv cev ntawm Fe2 ntxiv yog ib qho tseem ceeb heev. Qhov no yog vim Fe2 ntxiv rau hauv cov tshuaj plating yog yooj yim oxidized rau Fe3 ntxiv rau ntawm lub anode nyob rau hauv cov huab cua los yog thaum lub sij hawm electroplating txheej txheem. Thaum PH tshaj 2.5, nag lossis daus yuav tsim. Ntawm qhov tod tes, thaum muaj qhov loj tam sim no yog monopolized, nag lossis daus ntawm Fe (OH) 3 txawm tshwm sim hauv qee qhov chaw uas nyob ib sab ntawm lub cathode nto vim qhov paug ntawm me me ntawm hydrogen ions, thiab yog adsorbed rau cathode nto. . Xws li pinholes, burrs thiab brittleness. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum koom nrog qee qhov ntawm Fe2 ntxiv rau tus neeg saib xyuas lub zog thiab cov nyiaj seem ntawm tus neeg sawv cev tsis zoo hauv cov tshuaj plating, txhawm rau tswj lub zog ntawm cov tshuaj plating.

Lub zog ntawm cov txheej txheem plating yog hais txog: kom ntseeg tau tias cov txheej txheem ntawm cov xim dawb tuaj yeem tau txais los ntawm kev tsim khoom, tiv thaiv kev tsim ntawm ferric hydroxide, ductility, leveling, uniformity, toughness, adhesion, corrosion resistance, hardness, thickness ntawm txheej. . Kev siv dav dav yuav tsum ua raws li qhov ntsuas.

Txhawm rau kom ua tiav tib lub hom phiaj zoo li ci ntsa iab npib tsib xee, Hangzhou Huifeng Surface Technology Research Institute tau ua ib qho me me ntawm kev tshawb fawb ntawm cov tshuaj ntxiv ntawm nickel-hlau plating, thiab tau txais ntau yam kev sib xyaw ua ke nrog kev ua haujlwm zoo kom tau raws li cov lus hais saum toj no. . Ib qho txawv txav ntawm cov tshuaj sib xyaw ua ke no yog tias lawv txav mus rau qhov kev sib xyaw ua ke ntawm cov neeg ua haujlwm nyuaj thiab cov neeg ua haujlwm muaj zog, cov neeg ua kom pom kev zoo thiab cov neeg ua haujlwm qib.
