Emva kwesheet steel stainlessiyazoba ngocingo, igcina ukuxhathisa umhlwa kunye neziphumo zokuthintela umhlwa.Nangona kunjalo, xa kuthelekiswa namaphepha ensimbi angenasici angakhange athathe umzobo wocingo, ukusebenza kunokuncipha kancinci.
Okwangoku, olona nyango luqhelekileyo lomphezulu lwamaphepha ensimbi engenasici ngumgangatho oqaqambileyo kunye nomphezulu we-matte.Amaphepha entsimbi angenasici, emva konyango lomzobo wocingo, axhathise kakhulu ukunxitywa kunamashiti entsimbi aqaqambileyo aqhelekileyo.Nangona kunjalo, ukuxhathisa umhlwa kunye nokusebenza kokuthintela umhlwa kwamaphepha ensimbi engenasici emva konyango lomzobo wocingo kunokuncipha.Ukugcinwa okungafanelekanga ekuhambeni kwexesha kunokukhokelela kumhlwa kwangaphambili xa kuthelekiswa nomphezulu oqaqambileyoamashiti ensimbi engenasici.
Yenziwe ngentsimbi eshayinayoyenye yeentsimbi ze austenitic stainless, ikakhulu yenziwe ngezinto ezifana carbon, nickel, kunye chromium.I-Chromium inokwenza ifilimu ekhuselayo ecebileyo ngechromium kumphezulu wamaphepha ensimbi engenasici, ukuthintela i-oxidation eyongezelelweyo kunye nokubola.Unyango lomzobo wocingo lungonakalisa ifilimu ekhuselayo ene-chromium phezu komhlaba, ekhokelela ekunciphiseni ukuxhatshazwa kwe-corrosion kunye nokusebenza kokuthintela umhlwa kwiishiti zensimbi ezingenasici.Kwiimeko ezingqongileyo ezirhabaxa ezinokuchanabeka emoyeni, elangeni, nasemvuleni, umhlwa nomhlwa zinokwenzeka lula.
Ngaphambi kokwenza unyango lokuzoba ngocingo kumaphepha entsimbi, kubalulekile ukusebenzisa unyango lokuthintela umhlwa.Unyango lwe-Passivation lusekelwe kwithiyori yefilimu ebhityileyo, ebonisa ukuba ukugqithisa kwenzeka xa isinyithi sisebenzisana ne-medium, okukhokelela ekubunjweni kwefilimu enqabileyo kakhulu, exineneyo, egqunywe kakuhle kwi-metal surface.Le filimu isebenza njengesithintelo, ukuthintela ukudibanisa ngokuthe ngqo phakathi kwesinyithi kunye ne-corrosive medium kunye nokukhusela isinyithi kwi-corrosion.
