Mushure mesimbi isina tsvina pepainodhirowa waya, inoramba ichiramba ichiramba kuita ngura uye kudzivirira ngura.Nekudaro, zvichienzaniswa nesimbi isina simbi mashizha asina kudhirowa waya, kuita kunogona kuderera zvishoma.
Parizvino, kurapwa kwakajairika kwepamusoro kwesimbi isina simbi mashiti inopenya pamusoro uye matte pamusoro.Matte pamusoro pesimbi isina tsvina masheets, mushure mekudhirowa kwewaya, anoshingirira kupfeka kupfuura anogara akajeka pamusoro pemapepa esimbi asina tsvina.Nekudaro, iyo corrosion kuramba uye ngura yekudzivirira kuita kwesimbi isina tsvina mashiti mushure mekudhirowa kwewaya kurapwa kunogona kudzikira.Kusachengetedzwa kwakashata nekufamba kwenguva kunogona kutungamira kune yekutanga ngura kana ichienzaniswa nekupenya kwepamusoromachira esimbi asina tsvina.
Simbi isina ngurandeimwe yeaustenitic simbi isina tsvina, inonyanya kuumbwa nezvinhu zvakaita sekabhoni, nickel, uye chromium.Chromium inogona kuumba chromium-rich inodzivirira firimu pamusoro pemashizha esimbi isina tsvina, kudzivirira imwe oxidation uye corrosion.Iyo yekudhirowa kwewaya kurapwa inogona kukuvadza chromium-yakapfuma yekudzivirira firimu pamusoro, zvichitungamira kudzikira mukudzikira kwekuora uye kuita ngura kwekudzivirira kuita kwesimbi isina tsvina.Munzvimbo dzakaoma dzine mhepo, zuva, nemvura, ngura uye ngura zvinogona kuitika zviri nyore.
Usati waita waya yekudhirowa kurapwa pamapepa esimbi asina tsvina, zvakakosha kuisa passivation ngura yekudzivirira kurapwa.Passivation kurapwa kunobva pane yakaonda firimu dzidziso, zvichiratidza kuti passivation kunoitika kana simbi ichipindirana nepakati, zvichikonzera kuumbwa kweakaonda kwazvo, akaonda, akavhara zvakanaka passivation firimu pamusoro pesimbi.Iyi firimu inoshanda sechipinganidzo, ichidzivirira kusangana kwakananga pakati pesimbi uye inoparadza svikiro uye kudzivirira simbi kubva mukuora.
