1. Mfundo yofunika.Chifukwa nthaka sisintha mosavuta mu mpweya wouma, ndipo mu mpweya chinyezi, pamwamba akhoza kupanga wandiweyani kwambiri filimu ya zinki carbonate, amene angathe kuteteza mkatikati kuti dzimbiri.Ndipo pamene chophimbacho chawonongeka pazifukwa zina ndipo masanjidwewo sali aakulu kwambiri, matrix a zinki ndi zitsulo amapanga selo yaying'ono, kotero kuti masanjidwewo a fastener amakhala cathode ndipo amatetezedwa.Amagwiritsidwa ntchito kwambiri pamayendedwe apagalimoto ndi m'mafakitale ena, koma chomwe chimafunika ndi trivalent chromium passivation wosanjikiza, zinki faifi tambala aloyi plating chatsekedwa ❖ kuyanika, kuchepetsa wosanjikiza zoipa ndi poizoni wa hexavalent chromium passivation.
2, magwiridwe antchito.Zinc ❖ kuyanika ndi wandiweyani, bwino crystallization, yunifolomu ndipo palibe pores, zabwino dzimbiri kukana;Ndi woyera, nthaka plating wosanjikiza mu asidi, dzimbiri zamchere pang'onopang'ono, monga chifunga Eng bwino kuteteza zolimba mchenga-kukonza masanjidwewo, kanasonkhezereka wosanjikiza aumbike pambuyo chromate passivation, mtundu woyera, asilikali wobiriwira, wokongola ndi zosavuta, ndi ena kudzikongoletsa kugonana, chifukwa wosanjikiza kanasonkhezereka ali ductility zabwino, choncho akhoza kuthamangira, kugudubuza, ozizira kupinda ndi kupanga osati kuwononga ❖ kuyanika.
3. Kuchuluka kwa ntchito.Electrogalvanizing imaphatikizapo minda yowonjezereka, zopangira zomangira zakhala zikugwiritsidwa ntchito kwambiri popanga makina, zamagetsi, zida zolondola, makampani opanga mankhwala, zoyendera, zamlengalenga ndi zina zotero mu chuma cha dziko ndizofunika kwambiri.
