Iyo yakanakisa corrosion resistance yesimbi isina tsvina inokonzerwa nekuumbwa kwefirimu isingaoneki ye oxide pamusoro pesimbi, zvichiita kuti irege.Iyi firimu yepasi inoumbwa semugumisiro wesimbi inopindirana neokisijeni kana yaiswa mumhepo, kana semugumisiro wekusangana nedzimwe nzvimbo dzine oxygen.Kana iyo passivation firimu yakaparadzwa, simbi isina tsvina icharamba ichiora.Muzviitiko zvakawanda, iyo passivation firimu inongoparadzwa pamusoro pesimbi uye munzvimbo dzemunharaunda, uye mhedzisiro yekuora ndeyekugadzira makomba madiki kana makomba, zvichikonzera kugovaniswa zvisina kufanira gomba-kufanana ngura pamusoro pechinhu.
Kuitika kwekuora kwegomba kunogona kunge kuri nekuda kwekuvapo kweiyo chloride ion yakasanganiswa ne depolarizer.Kuora kwegomba kwesimbi dzinoita sesimbi isina tsvina kunowanzo kukonzerwa nekukuvadzwa kwenzvimbo kwemamwe maanioni ane hukasha kune firimu rekuita, kudzivirira nzvimbo yekusagadzikana nekusagadzikana kwakanyanya.Kazhinji nharaunda yeoxidizing inodiwa, asi iyi ndiyo chaiyo mamiriro epasi panoitika gomba.Iyo yepakati yepitting corrosion kuvapo kweiyo heavy metal ions yakadai seFE3+, Cu2+, Hg2+ muC1-, Br-, I-, Cl04-solutions kana chloride mhinduro dzeNa+, Ca2+ alkali uye alkaline pasi simbi ions ine H2O2, O2, etc.
Mutengo wegomba unowedzera nekuwedzera tembiricha.Semuenzaniso, mune imwe sarudzo ine mutsara we4% -10% sodium chloride, iyo yakanyanya kurasikirwa uremu nekuda kwegomba corrosion inosvika pa90 ° C;nokuda kweimwe dilute solution, iyo yakawanda inoitika pakupisa kwepamusoro.
