Corten steel yog cov hlau alloy. Tom qab ob peb xyoos ntawm kev tawm sab nraum zoov, cov txheej txheem xeb kuj tuaj yeem tsim rau ntawm qhov chaw, yog li nws tsis tas yuav tsum tau pleev xim rau kev tiv thaiv. Lub npe nrov tshaj plaws ntawm weathering steel yog "cor-ten", uas yog lub ntsiab lus ntawm "corrosion resistance" thiab "tensile zog", yog li nws feem ntau hu ua "Corten steel" hauv lus Askiv. Tsis zoo li cov hlau tsis muaj steel, uas tuaj yeem ua kom tsis muaj xeb, huab cua tsuas yog oxidizes ntawm qhov chaw thiab tsis nkag mus rau sab hauv, yog li nws muaj cov khoom tiv thaiv corrosion siab.
Corten steel yog suav tias yog "nyob" cov ntaub ntawv vim nws txoj kev loj hlob tsis zoo / oxidation txheej txheem. Qhov ntxoov ntxoo thiab lub suab yuav hloov mus rau lub sijhawm, nyob ntawm qhov zoo ntawm cov khoom, qhov twg nws raug ntsia, thiab lub voj voog huab cua ntawm cov khoom mus dhau. Lub sijhawm ruaj khov ntawm oxidation mus rau kev loj hlob yog feem ntau 12-18 lub hlis. Cov nyhuv xeb hauv zos tsis nkag mus rau cov khoom siv, yog li cov hlau ib txwm tsim cov txheej txheem tiv thaiv kom tsis txhob xeb.
Corten steel yuav tsis xeb. Vim nws cov tshuaj lom neeg muaj pes tsawg leeg, nws muaj kev tiv thaiv siab dua rau atmospheric corrosion dua li cov hlau me me. Qhov saum npoo ntawm cov hlau yuav xeb, tsim cov txheej txheem tiv thaiv uas peb hu ua "patina."
Cov nyhuv corrosion inhibition ntawm verdigris yog tsim los ntawm cov kev faib tawm thiab cov concentration ntawm nws cov ntsiab lus alloying. Cov txheej tiv thaiv no yog khaws cia raws li patina txuas ntxiv txhim kho thiab rov tsim dua tshiab thaum raug huab cua. Yog li nws tuaj yeem siv tau ntev yam tsis muaj kev puas tsuaj yooj yim.
