Mukamagwira ntchito, pamsonkhanowu, kuwotcherera, kuyendera msoko, ndi madontho, ndi zodetsa, zodetsa, kupaka utoto, utoto umayambitsidwa. Zinthu izi zimakhudza chitsulo chosapanga dzimbiri, kuwononga filimu yake ya passtivation, ndikuchepetsa kuwonongeka kwa makanema omwe ali ndi media mu mankhwala osokoneza bongo omwe amasungidwa pambuyo pake.
Akasinja osapanga dzimbiri, chifukwa chonyamula mankhwala osiyanasiyana, ali ndi zofunikira zopewera kuipitsidwa kwa katundu. Popeza malo okhalamo osapanga dzimbiri amasamwa, ndiofala kuchita zamakina, mankhwala, kapenaKupukuta kwa ElectrolyticPa mbale, zida zachitsulo zosapanga dzimbiri, ndi zida musanayeretse, kunyamula, komanso kungokhala kupititsa patsogolo kukana kwa chitsulo chosapanga dzimbiri.
Kanema wa passtivation pa chitsulo chosapanga dzimbiri ali ndi mawonekedwe amphamvu ndipo sayenera kuonedwa kuti amasungunuka kwathunthu kuti ayambe kutuka koma m'malo mwake mapangidwe osanjikiza. Zimakhala zowonongeka pamaso pa opulumutsa (monga chloride manyezi) ndipo imatha kuteteza ndikukonza pamaso pa oxidants (monga mpweya).
Ngati chitsulo chosapanga dzimbiri chimawonekera pamlengalenga, mafomu a kanema wa oxide.
Komabe, katundu woteteza wa filimuyi sikokwanira. Kudzera pa acid, makulidwe a 10μm of theMalo osapanga dzimbiriimasungidwa, ndipo ntchito yamankhwala a acid imapangitsa kuti zisudzo zikhale zoperewera kuposa malo ena apamwamba. Chifukwa chake, kunyamula kumapangitsa kuti malo onse azikhala osagwirizana. Chofunika, kudzera pakusankha ndi pasipoti, chitsulo ndi malo ake osungunuka mosiyanasiyana poyerekeza ndi chromium ndi oxides, ndikuchotsa pamwamba ndi chromium. Pansi pa zochitika za ogula, kanema wokhazikika komanso wokhazikika amapangidwa, zomwe zingatheke bwino kwambiri pazachilengedwechi.
