Electrochemical corrosion
Cov ntawv hlau tsis xeb yog khawb vim tiv tauj nrog cov pa roj carbon hlau, thiab tom qab ntawv tsim cov xov tooj cua galvanic nrog nruab nrab corrosive, uas yuav ua rau hluav taws xob hluav taws xob xeb. Yog tias qhov ua kom pickling passivation tsis zoo, zaj duab xis passivation ntawm cov phaj yuav tsis sib xws lossis nyias dhau, uas yuav yooj yim ua rau hluav taws xob xeb xeb, txiav slag, txaws thiab lwm yam tshuaj xeb kom ua raws lub phaj, thiab tom qab ntawv nrog corrosive media. Thawj lub roj teeb, uas tsim hluav taws xob hluav taws xob. Kev tsis huv pickling passivation ntxuav tau ua rau cov khoom siv tshuaj lom xeb ntawm cov khoom khaws cia seem uas seem thiab cov phaj, thiab tom qab ntawd electrochemical corrosion nrog phaj.
