Evaluation of Lutein Polyester Film as Corrosion Inhibitor in Steel AISI 1018

The effect of the application of lutein polyester film as a corrosion inhibitor in AISI 1018 carbon steel in a 3.5% NaCl solution at room temperature and without stirring was studied. The corrosion rate assessment of carbon steel was performed using electrochemical techniques such as potentiodynamic polarization. The results indicated a decrease in the corrosion rate of AISI 1018 carbon steel as the lutein concentration was increased from 0.053 mm/year without film to 0.0083 mm/year for a concentration of 0.04 g/mL. Lutein polyester showed properties to be used as corrosion inhibitor.
