Electroplating hluav taws xob cua sov tube chim plating txheej txheem

Qhov ceev tam sim no sib txawv heev. Txawm hais tias cathode tam sim no ceev ntawm chim plating yog qhov loj, vim qhov sib txawv loj nyob rau hauv tam sim no ceev, feem ntau ntawm cov tam sim no tau noj ntawm lub workpiece nrog high tam sim no ceev, thiab qhov nruab nrab tam sim no ceev yog heev me me. Yog li ntawd, lub cathode tam sim no efficiency yog tsawg. Thickness yog qhov nyuaj rau lav.

Kuj tseem muaj tshuaj yaj yeeb yaj kiab thaum lub sij hawm plating txheej txheem. Thaum lub workpiece dov, qhov tam sim no yuav tsis sib tshuam, thiab lub thickening ntawm txheej yuav tsum tau ntev lub thoob txheej txheej. Txawm li cas los xij, nws tseem nyuaj rau thicken lub txheej hauv zos.

Kev cuam tshuam ntawm qhov xwm txheej ntawm electroplated hluav taws xob cua sov raj ntawm kev tiv thaiv

Cov tsos ntawm cov khoom siv hauv paus yog ib qho ntawm cov ntsiab lus tseem ceeb uas cuam tshuam rau lub peev xwm npog. Kev xyaum qhia tau hais tias thaum cov hlau yog electro-deposited ntawm cov khoom sib txawv substrate, lub peev xwm npog ntawm tib plating tov yog txawv thiab zoo heev. Piv txwv li, thaum chromic acid tov yog siv rau chrome plating, thaum hlau chrome accumulates ntawm tooj liab, npib tsib xee, tooj dag thiab hlau, cov kev pab them nqi ntawm cov tshuaj plating yuav txo qis sequentially. Qhov no yog vim hais tias thaum cov hlau ions rov qab los thiab sau rau ntawm cov khoom sib txawv matrix, qhov tseem ceeb ntawm lawv cov khoom muaj peev xwm sib txawv heev. Lub peev xwm poob nrog me me overpotential yog qhov zoo dua, thiab tus nqi ntawm nws lub peev xwm poob tuaj yeem ncav cuag txawm tias nyob rau hauv ib feem nrog qis dua tam sim no, yog li nws lub peev xwm npog qhov zoo dua. Kev cuam tshuam ntawm qhov chaw ntawm cov khoom siv matrix ntawm lub peev xwm npog ntsej muag yog qhov nyuaj dua.

Feem ntau hais lus, lub peev xwm npog ntawm tib lub plating tov rau ntawm qhov chaw ntawm lub substrate nrog siab smoothness yog zoo dua li ntawm qhov ntxhib nto. Vim hais tias ntawm thaj chaw loj, qhov tseeb, qhov ceev tam sim no yog qhov tsawg, thiab nws nyuaj rau ncav cuag qhov sib cais ntawm cov hlau, tab sis tsuas yog ntau cov hydrogen sib cais. Tsis tas li ntawd, yog tias qhov chaw ntawm lub substrate tsis raug kho kom zoo ua ntej plating, muaj cov roj yeeb yaj kiab uas tsis raug tshem tawm, ntau yam txheej txheej txheej txheej txheej los yog av, thiab lwm yam. npog peev xwm.
