Dab tsi yog Qhov Kev Ntsuas Tshuaj Tiv Thaiv Corrosion?

Dab tsi yog qhov kev ntsuam xyuas ntsev tsuag corrosion?
ntsev tsuag corrosion yog ib qho ntawm feem ntau thiab puas atmospheric corrosion. Lub corrosion ntawm ntsev tsuag rau saum npoo ntawm cov ntaub ntawv hlau yog tshwm sim los ntawm electrochemical cov tshuaj tiv thaiv ntawm cov tshuaj chloride ions thiab cov hlau puab los ntawm oxide txheej thiab txheej tiv thaiv ntawm cov hlau nto. Nyob rau tib lub sijhawm, chloride ion muaj qee lub zog hydration, uas yooj yim rau adsorbed hauv qhov pores thiab tawg ntawm cov hlau nto kom nyem tawm thiab hloov cov pa hauv txheej oxide, thiab hloov cov oxide insoluble mus rau hauv cov tshuaj chloride soluble, yog li ntawd. passivated nto los ua ib tug active nto.
