Corrosion Inhibition Effect of Pyridine-2-Thiol for Brass in An Acidic Environment.

In this study, the inhibitive performance of pyridine-2-thiol added to a corrosive solution was investigated for brass using potentiodynamic polarization, electrochemical impedance spectroscopy, and X-ray photoelectron spectroscopy. Electrochemical experiments were performed with different inhibitor concentrations in 0.5 M HSO as the corrosive medium.
