Plating yog txheej txheem ntawm plating ib txheej nyias ntawm lwm cov hlau los yog alloys ntawm qee qhov chaw hlau siv lub hauv paus ntsiab lus ntawm electrolysis, thiaj li tiv thaiv cov hlau oxidation (xws li xeb), txhim kho hnav tsis kam, hluav taws xob conductivity, reflection, corrosion kuj (tooj liab sulfate, thiab lwm yam) thiab txhim kho cov tsos thiab lwm yam.
Thaum electroplating, txheej hlau los yog lwm yam insoluble cov ntaub ntawv raws li lub anode, lub workpiece yuav tsum plated raws li cathode, txheej hlau cation yog txo los tsim ib txheej ntawm lub workpiece yuav plated. Txhawm rau tshem tawm qhov cuam tshuam ntawm lwm cov cations, thiab ua kom cov txheej txheej zoo li qub, ruaj khov, yuav tsum tau siv cov txheej txheem ntawm cov hlau cations uas muaj cov txheej txheem los ua cov tshuaj electroplating, txhawm rau kom cov concentration ntawm cov hlau cations ntawm txheej tsis hloov.
Lub hom phiaj ntawm electroplating yog hloov cov cuab yeej saum npoo av lossis qhov loj ntawm cov substrate los ntawm plating hlau txheej rau nws. Electroplating tuaj yeem txhim kho qhov kev tiv thaiv corrosion ntawm cov hlau (corrosion resistant hlau yog siv rau txheej hlau), nce hardness, tiv thaiv hnav, txhim kho hluav taws xob conductivity, smoothness, kub tsis kam thiab zoo nkauj nto.
Kub dip galvanizingFeem ntau yog siv rau hauv cov khoom lag luam, kub dip galvanizing txheej feem ntau yog siab tshaj 35μm, cov qauv yuav tsum muaj txog 80μm, qee qhov txawm tias siab li 200μm, muaj peev xwm muaj peev xwm zoo, tuab txheej, nyob rau hauv lub xyoo, lossi tiv thaiv sab hauv, feem ntau yog siv nyob rau hauv ntau yam kab accessories los yog cov khoom tseem ceeb ruaj khov. Electroplating txheej yog sib xws ntau tshaj li kub dip txheej, feem ntau thinner, los ntawm ob peb microns mus rau kaum ob ntawm microns. Los ntawm electroplating, muaj peev xwm ua tau nyob rau hauv cov khoom siv kho kom zoo nkauj thiab kev tiv thaiv ntawm ntau yam kev ua haujlwm saum npoo, tseem tuaj yeem kho qhov hnav thiab ua haujlwm yuam kev ntawm workpiece, hluav taws xob galvanized txheej yog thinner, feem ntau yog txhawm rau txhim kho corrosion kuj ntawm cov hlau (txheej hlau nrog corrosion resistant hlau), nce hardness, tiv thaiv hnav thiab tsim kua muag, txhim kho hluav taws xob conductivity, thermal stability thiab nto smoothness.
