The influence of the sodium salt of N-lauroyl sarcosine (NLS) on corrosion of a manganese steel was studied in aerated, nearly neutral saline solutions at room temperature and under various hydrodynamic conditions. The inhibitive efficiency of NLS was examined using gravimetric tests, polarization curves, and electrochemical impedance spectroscopy (EIS). The additive slowed the corrosion phenomena, either generalized or localized, that occurred on steel, but only at the high rotation speed of the rotating cylinder electrode (RCE). The mechanism of action was anodic and probably resulted from precipitation of an insoluble product on the anodic areas.
