Kutetezedwa kwa kupaka zinki pazitsulo zachitsulo kumakhala ndi mfundo ziwiri: kumbali imodzi, ngakhale nthaka imakhala yogwira ntchito komanso yosavuta kutulutsa oxidize kuposa chitsulo, koma filimu yake ya oxide si yotayirira komanso yophatikizika ngati iron oxide.Kuchuluka kwa okusayidi wosanjikiza komwe kumapangidwa pamwamba kumalepheretsa kuwonjezereka kwa zinki mkati.Makamaka pambuyo passivation wa kanasonkhezereka wosanjikiza pamwamba pa okusayidi wosanjikiza ndi wandiweyani ndi wandiweyani, palokha ali mkulu makutidwe ndi okosijeni kupewa.
Komano, pamene pamwamba pamalatawosanjikiza ndi kuonongeka, kuvumbulutsa mkati chitsulo masanjidwewo, chifukwa nthaka yogwira kuposa chitsulo, pa nthawi iyi, nthaka ali ndi udindo wa nsembe nthaka anode, nthaka adzakhala oxidized pamaso chitsulo, kuteteza wosanjikiza chitsulo sichidzawonongeka.
Orchard wapadera electroplating ndondomeko waya ndi kutentha kwa nthaka njira kumiza plating, liwiro kupanga, wandiweyani koma wosafanana ❖ kuyanika, msika amalola 1 otsika makulidwe 45 microns, mpaka 300 microns.Ndi mdima wandiweyani, umadya zitsulo zambiri za zinki, ndipo umapangika munsanjika ndi chitsulo choyambira, ndipo umalimbana bwino ndi dzimbiri.Kutentha kwa dip galvanizing kumatha kupitilira zaka zambiri m'malo akunja.
Orchard wapadera electroplating ndondomeko waya owala woyera,waya wamalatakutumizidwa mu malo owuma ndi mpweya wokwanira, sangatumizidwe kumalo onyowa.Waya kanasonkhezereka sangakhoze kuikidwa pamodzi ndi asidi ndi zamchere zinthu kuteteza zimachitikira mankhwala ndi dzimbiri wa kanasonkhezereka waya.Waya wamalata ayeneranso kuyikidwa lathyathyathya, kuteteza zigzag kuukira mapindikidwe.
