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). NLS slowed the corrosion phenomena, either generalized or localized, that occured on steel, but only at high rotation speed of the rotating cylinder electrode (RCE). The mechanism of action eas anodic and probably resulted from the precipitation of an insoluble product on the anodic areas.

Abstract

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). NLS slowed the corrosion phenomena, either generalized or localized, that occured on steel, but only at high rotation speed of the rotating cylinder electrode (RCE). The mechanism of action eas anodic and probably resulted from the precipitation of an insoluble product on the anodic areas.
