Ngesikhathi sokuphatha, umhlangano, ukufundwa kwe-welding, ukucubungula i-welding seam, kanye nokucutshungulwa kwamathangi ensimbi angaphakathi, ukungcola okuhlukahlukene okunjengamabala kawoyela, ukungcola okuqinile kwensimbi, ukupenda, kwethulwa i-splal. Lezi zinto zithinta ikhwalithi engaphezulu yensimbi engenasici, zilimaze ukuthukuthela kwayo, zinciphise ukumelana nokuqina komhlaba, futhi zenze zithambekele kwimithombo yezindaba ezilimazayo emikhiqizweni yamakhemikhali eyathuthwa kamuva, okuholela ekugcekeni kwenhliziyo, ngisho nokuqhekeka kokugqwala.
Amathangi ensimbi engagqwali, ngenxa yokuthwala amakhemikhali ahlukahlukene, anezidingo eziphakeme zokuvimbela ukungcoliswa kwemithwalo. Njengoba ikhwalithi engaphezulu yamapuleti ensimbi akhiqizwe ngaphambi komhluthuli ampofu, kuwumkhuba owejwayelekile ukwenza imishini, yamakhemikhali, nomaI-electrolytic polishingNgamapuleti ensimbi engagqwali, imishini, nezinto ezisekelwe ngaphambi kokuhlanza, ukugeza, kanye nokudlulela ekuthuthukiseni ukumelana nokugqwala kwensimbi engenasici.
Ifilimu yokudlula ngensimbi engenasici inezici ezinamandla futhi akufanele ibhekwe njengemihle ephelele ekugculiseni kodwa esikhundleni sokwakhiwa kongqimba oluvikelayo. Kuvame ukulimala phambi kokunciphisa ama-ejenti (njengama-chloride ion) futhi kungavikela futhi kulungiswe phambi kwama-oxidants (njengomoya).
Lapho insimbi engenasici ivezwa umoya, amafomu efilimu oxide.
Kodwa-ke, le ndawo evikelayo yefilimu akwanele. Ngokusebenzisa i-acid picling, ubukhulu obuphakathi kwe-10μm weIngaphezulu lensimbi engenasiciKuyamangaza, futhi umsebenzi wamakhemikhali we-acid wenza izinga lokuchithwa kwamasayithi aphezulu kunezinye izindawo eziphezulu. Ngakho-ke, ukukhetha kwenza wonke umhlaba uthambekele ekulinganiseni okufanayo. Okusemqoka, ngokuthathwa kanye nokuhamba, i-iron kanye no-oxides bawo okoxide bancibilika ngokuqhathaniswa ne-chromium kanye noxisi waso, ukususa ungqimba lwe-chromium-okuchithekile nokucebisa indawo nge-chromium. Ngaphansi kwesenzo sokudlula kwe-oxivants, kwakhiwa ifilimu ephelele futhi ekhonondele yefilimu, kanye nale filimu ye-Chromium-Rich Passion efinyelela + i-1.0V (SCE), eduze kwamandla amahle, athuthukise ukuqina kokuphikiswa.
