Effect of cementite spheroidization on improving corrosion resistance of pearlitic steel under simulated bottom plate environment of cargo oil tank

The influence of cementite spheroidization on the corrosion resistance of a pearlitic steel used as cargo oil tank under the simulated bottom plate environment was investigated by employing microstructural characterizations, electrochemical measurements and gravimetric tests. The results indicate that for the as-forged pearlitic steel with the gradual accumulation of lamellar cementite on the surfaces, the galvanic effect between the anodic...
