Mumakore achangopfuura, kupenya kwechisikigo kwesimbi yemamiriro ekunze kwave kuwedzera kukurumbira sezvo mavara ayo eorenji uye mashava anozadzisa imwe nzira yechisikigo yekugadzira nyika uye kuveza kwebindu. Zvichida muenzaniso unonyanya kuzivikanwa ndeweAntony Gormley's Ngirozi yeKumaodzanyemba kuGateshead, kunyangwe ichishandiswa zvakanyanya mune dzakawanda zvishoma grandiose Settings dzakadai seyakavanzika uye yeruzhinji magadheni, mapaki uye maturu.
Iyi patina inoumbwa neiyo oxidation yesimbi, ichiita jira rakanaka rehutu. Simbi yakapfava yakapfava inoita chiedza uye brittle rust layer inochengeta mwando uye inobvumira oxygen kuti isvike pasimbi isina kuora, saka ngura inoenderera kusvika simbi yacho yaita ngura zvachose.
Iyi layer ine deser nekuda kweiyo alloying kuumbwa kwesimbi yemamiriro ekunze uye inoita semhinganidzo kuokisijeni uye mwando kubva mukuora.
Mamiriro ekunze esimbi anowanzo kupihwa uye kuiswa pamberi pekutanga kweiyo oxidation process uye kazhinji ine yakasviba grey kupera. Mushure mekuiswa, kuratidzwa kumvura, oksijeni, chiedza chezuva uye kusvibiswa kwemhepo kunotanga kuita ngura.
Zvese izvi zvinhu zvinokanganisa kumhanya kwekuwana inodzivirira oxide firimu uye kunyangwe kutaridzika kweiyo oxide firimu. MuNorthern Hemisphere, nzvimbo dzakatarisa kumaodzanyemba kana kumadokero dzinowanzopisa nekuomeswa nezuva kakawanda, zvichiita kuti pave nenzvimbo dzakapfava, dzakafanana pane dzakatarisa kuchamhembe nekumavirira, dzinokura zvishoma nezvishoma uye dzichiva dzakakura.
Maguta nenzvimbo dzemaindasitiri kazhinji dzine kusvibiswa kwemhepo kwakawanda, kunyanya sarufa, izvo zvinozotungamira kune oxidation yakadzika kupfuura kumaruwa.
Zvinosuruvarisa, kunyange iyo yakaisvonaka yakavharidzirwa pamusoro pesimbi inopisa inogona kusvibisa mvura inoyerera, uye iyo inofadza kune simbi, inogona kukurumidza kukuvadza matombo uye kongiri pavements. Zvisinei, kune nzira dzekudzivirira kuti izvi zvisaitike.
Kana corten steel drill yakaiswa padivi penzira, mhinduro yakajairika ndeyekusiya mukaha wesamende we5 kusvika 10 mm pakati pechibooreso uye pavement. Kana yakaiswa pane pedestal platform system, iyo gasket ichava nemhedzisiro yakafanana. Izvi zvinobvumira chero mwando kuti umhanye pasi pepasi rakapera (FFL) uye kutenderedza paving.
Kana nokuda kwechikonzero chipi nechipi mukaha usingakwanisike, muganho wakadzika, wakaoma unogona kufamba nechokunze kwemadziro ekudyara. Ichi chinhu chinoyevedza chinobatsira nekudonhedza mvura uye chinogonawo kuzadza nzvimbo nematombo.
Ikoko chigadzirwa chesimbi chinorembera pamusoro pemugwagwa, paAHLtinogona kupfekedza pasi uye zvishongedzo zvechigadzirwa nehupfu kuti zviite sesimbi yemamiriro ekunze, asi pasina oxidation inotungamirira kumarara asina kunaka.
