Methionine as Corrosion Inhibitor of Brass in O2-Free 1M NaOH Solution
Methionine (MET) as a corrosion inhibitor for brass in O2-free 1M NaOH solution was investigated using weight loss, polarization curves, electrochemical impedance spectroscopy(EIS). The surface morphology after corrosion test was observed by scanning electron microscopy (SEM). Results indicate that MET is a cathodic inhibitor, and the inhibition efficiency increases with MET concentration.
