Corrosion Inhibition of Strictosamide on Brass in Presence of Chlorides for their Conservation

Abstract

By means of the technique of Electrochemical Impedance Spectroscopy, the protective effect of Paraloid as coating and with the addition of strictosamide as corrosion inhibitor was analyzed. At a concentration of 50 mg/m2, a 69% of efficiency was reached, being the best concentration to protect the metallic surface. However, when the strictosamide was applied in concentrations of 20 mg/m², it was observed that the corrosion was promoted, even more than when the Paraloid was not applied.
