What Are The Differences Between Chemical And Electrochemical Corrosion?
Chemical corrosion: It occurs dry state Local attack to metal by environment Chemical corrosion is self-controlled It follows adsorption mechanism Ex: formation of mild scale on iron surface Electrochemical corrosion: Wet state (i.e) presence in moisture Large number of cathodic and anodic areas It is continuous process It follows electrochemical reaction Ex: rusting of iron in moisture
