Atmospheric Ib puag ncig
Nyob deb nroog Atmospheric Environment:
Alloy steel daim hlau feem ntau muaj qhov zoo corrosion kuj nyob rau hauv qhov chaw nyob deb nroog atmospheric. Muaj tsawg cov pa phem nyob rau hauv cov huab cua nyob deb nroog, thiab lub ntsiab corrosive yam yog cov av noo thiab oxygen. Yog tias cov hlau hlau phaj muaj qhov tsim nyog ntawm cov hlau alloy xws li chromium, oxide zaj duab xis tsim rau ntawm nws qhov chaw tuaj yeem tiv thaiv qhov chaw me me corrosive. Piv txwv li, ib lub phaj hlau hlau uas muaj 12% chromium tuaj yeem tiv thaiv kev yaig ntawm cov pa thiab cov dej me me nrog nws cov chromium oxide zaj duab xis rau ntawm qhov chaw nyob rau hauv ib puag ncig atmospheric nyob deb nroog thiab feem ntau tuaj yeem nyob tsis muaj kev cuam tshuam rau lub sijhawm ntev.
Nroog Atmospheric Ib puag ncig:
Cov huab cua hauv nroog muaj cov pa phem ntau dua, xws li sulfur dioxide, nitrogen oxides, thiab cov khoom me me. Cov pa phem no yuav ua kom lub zog ntawm cov hlau alloy steel phaj. Sulfur dioxide reacts nrog noo noo nyob rau hauv cov huab cua los tsim sulfurous acid, thiab sulfurous acid yog acidic thiab yuav muaj ib tug corrosive nyhuv nyob rau saum npoo ntawm alloy steel daim hlau. Cov hlau nyob rau hauv cov hlau hlau phaj yuav hnov mob nrog sulfurous acid los tsim ferrous sulfate, uas ua rau xeb ntawm lub phaj nto. Txawm li cas los xij, kev tiv thaiv corrosion ntawm cov hlau hlau hlau uas muaj npib tsib xee, molybdenum thiab lwm yam hlau alloy yuav raug txhim kho nyob rau hauv ib puag ncig no. Piv txwv li, nyob rau hauv lub atmospheric ib puag ncig nyob ze rau hauv nroog industrial cheeb tsam, hlau alloy hlau daim hlau uas muaj npib tsib xee thiab molybdenum corrode ntawm tus nqi qeeb qeeb dua li cov pa roj carbon zoo tib yam. Qhov no yog vim npib tsib xee tuaj yeem txhim kho cov tshuaj tiv thaiv corrosion ntawm cov hlau phaj, thiab molybdenum tuaj yeem txhim kho lub peev xwm ntawm cov phaj hlau los tiv thaiv corrosion ntawm acidic media.

Marine Atmospheric Ib puag ncig:
Marine atmospheric ib puag ncig yog nplua nuj nyob rau hauv ntsev, thiab cov chloride ion nyob rau hauv nws yog ib tug heev corrosive nruab nrab. Chloride ions tuaj yeem rhuav tshem cov yeeb yaj kiab tsis zoo rau ntawm cov hlau hlau hlau, ua rau cov hlau ua rau pitting thiab crevice corrosion. Txawm tias cov hlau hlau hlau uas muaj chromium, npib tsib xee thiab lwm yam hlau alloy muaj kev sib tw zoo corrosion nyob rau hauv marine atmospheric ib puag ncig. Piv txwv li, nyob rau hauv cov ntug dej hiav txwv, zoo tib yam alloy steel daim hlau tej zaum yuav pom tseeb corrosion me ntsis nyob rau hauv ob peb lub hlis, thaum lub corrosion kuj ntawm alloy steel daim hlau nrog tshwj xeeb kev tiv thaiv ntsuas (xws li galvanizing thiab txheej nrog ntsev - pos huab - resistant coatings) yuav zoo heev. txhim kho. Nyob rau hauv lub marine atmospheric ib puag ncig, zinc txheej ntawm galvanized alloy steel phaj yuav nyiam corroded los tsim zinc compound tiv thaiv zaj duab xis, yog li tiv thaiv cov hlau phaj matrix.
