Kurasa kure ndizvo chaizvo zvisiri kuitika ne Weathering Steel. Nekuda kwekuumbwa kwayo kwekemikari inoratidza kuramba kusvibiswa kwemhepo zvichienzaniswa nesimbi yakapfava.

Corten simbi inorwisa ngura layer.

Corten simbi dzimwe nguva inonzi yakakwira-simba yakaderera-alloy simbi, zvakare imhando yesimbi yakapfava iyo inogadzirwa kugadzira dense, yakagadzikana oxide layer inopa chengetedzo yakakwana. Iyo pachayo inoumba firimu rakatetepa re iron oxide pamusoro, iyo inoshanda seyakaputira kurwisa kuwedzera ngura.
Okisijeni iyi inogadzirwa nekuwedzera alloying zvinhu zvakaita semhangura, chromium, nickel uye phosphorus, uye inofananidzwa nepatina inowanikwa pane isina kuvharwa simbi yakakandwa yakavhurika kumhepo.

Anti-ngura layer inofanira kudziviswa


Kuti uite inodzivirira oxide layer:

◉Simbi yeCorten inoda kuita mitsetse yekunyorova nekuomesa.

◉Kuratidzwa kune chloride ions kunofanira kudzivirirwa, sezvo chloride ions ichidzivirira simbi kubva pakuchengetedzwa zvakakwana uye inotungamira kumazinga asingagamuchirwe ekuora.

◉Kana iyo nzvimbo ikaramba ichinyorova, hapana chekudzivirira chinoumba.

◉Zvichienderana nemamiriro ezvinhu, zvinogona kutora makore akati wandei kugadzira patina yakaomesesa uye yakagadzikana isati yawedzera ngura inogona kudzikiswa kusvika padanho rakaderera.

Upenyu hwebasa re corten simbi.

Nekuda kweiyo yepamusoro corrosion kuramba kwecorten simbi pachayo, pasi pemamiriro akanaka, hupenyu hwesevhisi hwezvinhu zvakagadzirwa nesimbi yekorten hunogona kusvika makumi emakore kana kunyange zana.
