Steel pob plating txheej txheem

Electroplating yog txheej txheem electrochemical tshwm sim ntawm qhov sib txuas ntawm cov hlau thiab electrolyte. Pom tseeb, txhawm rau kom ntseeg tau tias cov khoom siv electroplating zoo, hauv kev tsim cov khoom lag luam yuav tsum nruj me ntsis xyuas kom meej tias cov electrolyte thiab plating nto ib txwm tswj kev sib cuag zoo, yog tias kev sib cuag ntawm lawv tsis zoo, cov tshuaj tiv thaiv electrochemical tsis tuaj yeem nqa tawm. Vim yog cov txheej txheem pretreatment lossis kev ua haujlwm tsis raug cai, cov roj, xeb thiab oxide daim tawv nqaij txuas rau saum npoo ntawm cov hlau plating cuam tshuam qhov kev sib cuag ncaj qha ntawm electrolyte thiab plating qhov chaw. Lawv yog sandwiched ntawm txheej txheej, yuav ua rau qhov zoo ntawm cov khoom tsis zoo, yog li cov hlau plating nto huv si thiab cov txheej txheem saum npoo yog thawj tus mob kom tau txais cov txheej txheem zoo. Rau lub sijhawm ntev, feem ntau ntawm cov xwm txheej zoo hauv kev tsim khoom tsis yog vim cov txheej txheem plating nws tus kheej, tab sis feem ntau yog vim kev kho tsis raug ua ntej plating. Yog li ntawd, cov txheej txheem smoothness, adhesion, corrosion kuj thiab lwm yam khoom muaj feem xyuam nrog kev kho ua ntej plating.
