2. Electrochemical corrosion: Scratches kpatara site na kọntaktị na akụkụ carbon ígwè na nhazi nke batrị bụ isi na mgbasa ozi na-emebi emebi, na-akpata mmebi nke electrochemical; Mgbakwunye nke nchara na-adịkarị mfe bekee dị ka slag igbutu na splashing na corrosive ọkara na-etolite isi batrị, na-akpata electrochemical corrosion; Anụ ahụ ntụpọ (undercuts, pores, cracks, enweghị fusion, enweghị penetration, wdg) na kemịkalụ ntụpọ (oke mkpụrụ ọka, segregation, wdg) na ịgbado ọkụ ebe na-etolite a isi batrị na corrosive usoro, na-akpata electrochemical corrosion. .
