The results showed that the corrosion resistance of the two stainless steels decread with the increa of Cl ? concentration. After 48?h of corrosion, when the Cl ? concentration was not less than 6?g·L ?1 , active sites where current density i信件格式

The lowest Cl ? concentration that caud the appearance of active sites on the surface of 2507 DSS was 20?g·L ?1 , with less surface corrosion products and lower degree of general corrosion.
