Electroplating yuav tsum muaj hluav taws xob tsawg-voltage siab tam sim no rau lub tank electroplating thiab cov khoom siv hluav taws xob uas muaj cov tshuaj electroplating, cov khoom yuav tsum tau plated (cathode) thiab anode. Cov tshuaj muaj pes tsawg leeg ntawm cov tshuaj electroplating sib txawv raws li cov txheej txheem, tab sis nws muaj cov ntsev tseem ceeb uas muab cov hlau ions, tus neeg sawv cev ua kom yooj yim uas tuaj yeem ua rau cov hlau ions hauv cov ntsev tseem ceeb los ua ib qho nyuaj, thiab tsis muaj qhov tsis zoo rau stabilizing pH. daws.
Anode activator thiab tshwj xeeb additives. Electroplating yog txheej txheem uas cov hlau ions hauv cov tshuaj plating raug txo rau cov hlau atoms los ntawm cov tshuaj tiv thaiv electrode nyob rau hauv qhov kev txiav txim ntawm sab nraud hluav taws xob teb, thiab cov hlau tso rau ntawm cathode. Yog li, qhov no yog cov txheej txheem hlau electrodeposition nrog rau cov kua theem loj hloov, cov tshuaj tiv thaiv electrochemical thiab electrocrystalization.
Nyob rau hauv lub plating da dej uas muaj cov plating tov, cov ntxuav thiab tshwj xeeb pretreated qhov chaw yuav tsum tau plated yog siv raws li cathode, thiab cov anode yog ua los ntawm plated hlau. Ob tug ncej txuas nrog rau qhov zoo thiab qhov tsis zoo ntawm DC fais fab mov. Cov tshuaj electroplating yog tsim los ntawm cov tshuaj aqueous uas muaj cov khoom sib txuas ntawm cov hlau plated, conductive ntsev, buffers, pH regulators, additives, thiab lwm yam.
