Abstract
In this work the study of the behaviour AISI 1018 in a buffered solution like NACETM177 with and without hydrocarbon. Polarisation curves indicated slopes changing with the hydrocarbon presence enhancing the reduction reaction and inhibiting oxidation. EIS technique shows high activity of steel in the solution at low frequencies, establishing that interaction of the ions in solution with the metal is enhanced by hydrocarbon, where the adsorption processes are governing the corrosion mechanism. The adsorption of corrosive agents prevents the formation and growth of a passive layer, even in the presence of hydrocarbon and the corrosion rate is high.
