Taw qhia rau Electrochemical Corrosion

Qhov corrosion uas tshwm sim thaum hlau reacts electrochemically nrog electrolyte yog hu ua electrochemical corrosion. Thaum lub sij hawm tus txheej txheem ntawm electrochemical corrosion, ib tug tam sim no generated. Electrochemical corrosion yog ib qho kev nthuav dav heev ntawm corrosion. Piv txwv xws li atmospheric corrosion thiab av corrosion. Nws feem ntau tshwm sim los ntawm kev tsim ntawm ntau cov micro-galvanic hlwb ntawm cov hlau nto vim muaj cov kab tsis huv (xws li cov pa roj carbon thiab lwm yam hlau) thiab cov yeeb yaj kiab nyias ntawm cov tshuaj electrolyte. Yog hais tias lub hauv paus hlau yog ntau reactive tshaj cov impurities, lub hauv paus hlau yuav yaj thiab corroded. Thaum lub npoo ntawm cov yeeb nkab steel raug rau huab cua ntub, dej vapor condenses ntawm qhov chaw thaum tib lub sijhawm nqus cov pa roj carbon dioxide los ntawm huab cua, ua rau muaj qhov tshwm sim ntawm micro-galvanic cell phenomenon thiab ua rau electrochemical corrosion.
