Özet

We study the inhibition effect of 2-thiobarbituric acid on the corrosion performance of low-carbon steel in a 0.5 M HCl solution by the methods of potentiodynamic polarization, electrochemical impedance spectroscopy, and long-term measurements of hydrogen release and variations of the corrosion potential depending on the time of immersion. The potentiodynamic polarization curves are used to determine the activation energy of corrosion within the temperature range 298-328 degrees K. It is shown that 2-thiobarbituric acid inhibits the process of corrosion of steel in solutions of hydrochloric acid. The efficiency of inhibition is proportional to the concentration of the inhibitor.
