Kwiminyaka yakutshanje, ukukhazimla kwendalo yentsimbi yemozulu iye yanda kakhulu njengoko i-orenji yayo emdaka kunye nemibala emdaka ihambelana nendlela yendalo yokujonga umhlaba kunye nomzobo wegadi. Mhlawumbi umzekelo odumileyo nguAntony Gormley's Angel of the North eGateshead, nangona isetyenziswa ngokubanzi kwiSettings ezininzi ezincinci ezifana neegadi zabucala kunye nezikawonke-wonke, iipaki kunye neeterraces.
Le patina yenziwe nge-oxidation yensimbi, yenza uluhlu oluhle lokugqwala. Intsimbi eqhelekileyo ethambileyo yenza i-rust light and brittle rust layer egcina ukufuma kwaye ivumela ioksijini ukuba ifikelele kwintsimbi engagqwaliswanga, ngoko ke i-corrosion iya kuqhubeka de intsimbi iphele.
Olu luhlu luxinene ngenxa yokwakhiwa kwe-alloying yensimbi yemozulu kwaye isebenza njengesithintelo kwi-oksijini kunye nomswakama ovela kwinkqubo yokubola.
I-Weathering steel idla ngokubonelelwa kwaye ifakwe ngaphambi kokuqala kwenkqubo ye-oxidation kwaye ngokuqhelekileyo inokugqiba okungwevu. Emva kofakelo, ukuvezwa kwamanzi, ioksijini, ukukhanya kwelanga kunye nongcoliseko lomoya kuqala inkqubo yokurusa.
Zonke ezi zinto zichaphazela isantya sokufumana ifilimu ye-oxide ekhuselayo kunye nokubonakala kwefilimu ye-oxide. KuMntla weIkhweyitha, iindawo ezijonge emazantsi okanye entshona zikholisa ukuba shushu kwaye zomiswe lilanga rhoqo, nto leyo ekhokelela ekubeni umphezulu ogudileyo, umphezulu ofanayo nalowo ujonge emantla nasentshona, othi uphuhle ngokucothayo kwaye ube yigranular.
Izixeko kunye nemimandla yemizi-mveliso idla ngokuba nongcoliseko lomoya ngakumbi, ngakumbi isulphur, nto leyo eya kukhokelela kubunzulu beoksijini kunasezilalini.
Ngelishwa, nokuba i-rust ecolekileyo yokugqoka kwintsimbi ye-weathering ingangcolisa amanzi ahambayo, kwaye ngelixa ikhangeleka kwintsimbi, inokonakalisa ngokukhawuleza i-pavements yamatye kunye nekhonkrithi. Nangona kunjalo, kukho iindlela zokuthintela oku kungenzeki.
Ukuba i-corten steel drill ifakwe ecaleni kwendlela, isisombululo esiqhelekileyo kukushiya ikhefu le-samente le-5 ukuya kwi-10 mm phakathi kwe-drill kunye ne-pavement. Ukuba ifakwe kwi-platform ye-pedestal system, i-gasket iya kuba nesiphumo esifanayo. Oku kuvumela naluphi na ukufuma ukubaleka ngaphantsi komgangatho ogqityiweyo (FFL) kunye nokujikeleza i-paving.
Ukuba ngenxa yaso nasiphi na isizathu umsantsa awunakwenzeka, umda onzulu, onegrabile unokuhamba ecaleni komphetho wodonga lokutyala. Olu luphawu olukhangayo olunceda ukukhupha amanzi kwaye lunokuthi luzalise indawo ngegrabile.
Apho imveliso yentsimbi yemozulu ijinga phezu kwendlela, eAHLsinokugubungela i-underside kunye nezixhobo zemveliso kunye nomgubo ukuze kubonakale ngathi yintsimbi yesimo sezulu, kodwa ngaphandle kwe-oxidation ekhokelela kwiimpawu ezingabonakaliyo.
