Electrochemical corrosion yog dab tsi?

Electrochemical corrosion yog hais txog kev xeb uas tshwm sim vim kev cuam tshuam ntawm electrochemical ntawm cov hlau thiab electrolyte. 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 lub micro-galvanic hlwb ntawm cov hlau nto, uas yog cov kab mob tsis huv (xws li cov pa roj carbon thiab lwm yam hlau) thiab npog nrog cov zaj duab xis 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 yuav condense rau ntawm qhov chaw thaum nqus cov pa roj carbon dioxide los ntawm huab cua, tsim ib qho micro-galvanic cell phenomenon thiab ua rau electrochemical corrosion.
