Electrochemical corrosion

Corrosion tshwm sim los ntawm cov kev cuam tshuam hauv tshuab hluav taws xob ntawm cov hlau thiab electrolytes yog ua tiav electrochemical corrosion. Thaum lub sij hawm cov txheej txheem ntawm electrochemical corrosion, hluav taws xob kom tsim tau. Electrochemical corrosion sawv cev rau ib qho kawg ntawm corrosion, encompassing tshwm sim xws li atmospheric corrosion thiab av corrosion. Hom corrosion no feem ntau tshwm sim los ntawm kev tsim cov roj ntau lub cev, piv txwv li ntawm cov kab hlau) thiab lwm yam xim hlau thiab lwm yam ntawm cov tshuaj ntsuab tov. Thaum cov hlau hauv paus yog ntau dua electrochemically nquag tshaj qhov impurities, cov hauv paus hlau undergoes thiab corrosion. Piv txwv li, thaum lub nplaim dej ntawm cov yeeb nkab steel yog nthuav tawm cov cua noo, dej vapor condenses ntawm cov npoo thiab ua kom muaj cov roj ntsha thiab ua rau hluav taws xob corrosion.
