Carbon Steel
Tshuaj Reaction Aspect: Cov khoom tseem ceeb ntawm cov hlau yog hlau thiab carbon. Thaum lub sij hawm alkaline - kev ntxuav, raws li qhov kub thiab txias, cov tshuaj tiv thaiv ntawm cov tshuaj alkaline (xws li sodium hydroxide tov) thiab hlau nrawm. Piv txwv li, hlau reacts nrog hydroxide ions nyob rau hauv alkaline tov los tsim ferrous hydroxide. Vim tias cov ntsiab lus ntawm cov pa roj carbon tsawg hauv cov hlau, nws muaj qhov cuam tshuam me me ntawm cov tshuaj tiv thaiv no. Tsis pub dhau qhov kub thiab txias (xws li 40 - 60 degree), feem ntau cov roj thiab lwm yam impurities raug tshem tawm, thiab nws muaj kev cuam tshuam me ntsis ntawm qhov roughness. Txawm li cas los xij, thaum qhov kub thiab txias dhau lawm, ntau cov khoom siv corrosion xws li ferrous hydroxide yog tsim thiab yuav khaws cia rau ntawm cov pa roj carbon steel nto, hloov nws cov qauv microscopic thiab ua rau lub ntsej muag roughness.
Micro-structural Change Aspect: Cov qauv siv lead ua ntawm carbon steel yog qhov yooj yim. Raws li qhov kub nce siab, cov thermal txav ntawm atoms hauv cov pa roj carbon steel intensifies, thiab lattice defects nce. Nyob rau hauv ib puag ncig alkaline, tshuaj lom neeg muaj feem yuav tshwm sim ntawm cov chaw tsis xws luag. Piv txwv li, nyob rau hauv ib thaj tsam ntawm grain, vim yog qhov tsis sib xws ntawm cov atoms, raws li qhov kub thiab txias, cov tshuaj alkaline feem ntau yuav hnov ​​​​mob nrog cov hlau atoms ntawm cov haujlwm no, ua rau cov nplej - ciam teb corrosion thiab ntxiv rau qhov chaw roughness. Tsis tas li ntawd, cov khoom tsim tawm corrosion tuaj yeem sau cov pores me me ntawm cov pa roj carbon steel, ntxiv rau qhov cuam tshuam rau qhov chaw morphology.

Hlau alloy
Cov nyhuv ntawm Alloy Elements: Alloy steel muaj ntau yam hlau alloy, xws li chromium (Cr), npib tsib xee (Ni), molybdenum (Mo), thiab lwm yam. Siv chromium - muaj cov hlau alloy ua piv txwv, chromium tuaj yeem tsim cov chromium oxide tuab. () tiv thaiv zaj duab xis ntawm cov hlau nto. Ntawm qhov kub thiab txias, cov yeeb yaj kiab tiv thaiv no yog qhov ruaj khov thiab tuaj yeem tiv thaiv sab hauv ntawm cov hlau los ntawm corroded los ntawm cov tshuaj alkaline. Txawm li cas los xij, thaum kub nce, qhov xwm txheej hloov. Piv txwv li, ib yam nkaus - qhov kub thiab txias yuav ua rau kev ncaj ncees ntawm cov yeeb yaj kiab tiv thaiv no. Vim hais tias ntawm qhov kub thiab txias, cov tshuaj tiv thaiv ntawm cov yeeb yaj kiab tiv thaiv thiab cov tshuaj alkaline nrawm nrawm, uas tuaj yeem ua rau ib nrab tawg lossis tawg ntawm cov yeeb yaj kiab tiv thaiv. Thaum cov yeeb yaj kiab tiv thaiv puas lawm, cov tshuaj alkaline yuav hnov ​​​​mob nrog cov ntsiab lus xws li hlau hauv cov hlau, ua rau lub ntsej muag roughness.
Kev sib cuam tshuam ntawm cov ntsiab lus sib txawv: Cov ntsiab lus sib txawv hauv cov hlau alloy kuj cuam tshuam nrog ib leeg. Piv txwv li, npib tsib xee tuaj yeem txhim kho qhov toughness thiab corrosion kuj ntawm steel. Thaum kub hloov pauv, npib tsib xee koom tes nrog lwm cov ntsiab lus (xws li hlau thiab chromium) cuam tshuam rau corrosion kuj ntawm hlau. Thaum qhov kub thiab txias, npib tsib xee - uas muaj cov hlau alloy yuav tiv taus corrosion ntawm alkaline ntau dua cov pa roj carbon steel, vim tias npib tsib xee tuaj yeem hloov cov khoom siv hluav taws xob ntawm cov hlau nto, ua rau cov tshuaj tiv thaiv corrosion tsis tshua muaj tshwm sim. Txawm li cas los xij, yog tias qhov kub thiab txias dhau qhov kev txwv ntawm kev sib koom ua ke los tiv thaiv corrosion ntawm cov ntsiab lus ntawm cov hlau alloy, qhov roughness ntawm cov hlau hlau tseem yuav nce ntxiv, tab sis cov qib thiab cov txheej txheem ntawm kev nce yuav txawv ntawm cov pa roj carbon steel. Piv txwv li, alloy steel tej zaum yuav muaj complex compounds generated los ntawm cov tshuaj tiv thaiv ntawm cov ntsiab lus alloy nrog cov alkaline tov nyob rau saum npoo, es tsis yog cov khoom siv corrosion yooj yim xws li ferrous hydroxide xws li carbon steel.

Stainless hlau
Cov nyhuv ntawm Passivation Zaj duab xis: Muaj cov zaj duab xis passivation ntuj (lub ntsiab lus tseem ceeb yog chromium oxide) ntawm stainless - steel nto, thiab zaj duab xis no ua rau cov hlau tsis muaj corrosion kuj zoo. Ntawm qhov kub thiab txias, zaj duab xis passivation no tuaj yeem tiv taus qhov yaig ntawm cov tshuaj alkaline thaum alkaline - ntxuav. Txawm li cas los xij, thaum kub nce, qhov kev ruaj ntseg ntawm cov yeeb yaj kiab passivation yuav raug sib tw. Piv txwv li, nyob rau hauv ib tug high-kub alkaline tov, lub passivation zaj duab xis yuav undergo ib lub zos dissolution thiab kho txheej txheem. Yog hais tias tus nqi dissolution ntau tshaj qhov kho tus nqi, nws yuav ua rau kev puas tsuaj ntawm passivation zaj duab xis ntawm stainless - steel nto.
