Corrosion Inhibition on Mild Steel Using PFOA Additives

摘要：

　　In this paper, the anticorrosive properties of perfluorooctanoic acid (PFOA) on Q235 mild steel corrosion were estimated in simulated seawater.XRD and EDS results showed that PFOA could penetrate the rust layer and adsorb on the surface of steel and destroy rust layer.Our polarization measurements revealed that PFOA is a useful inhibitor, with a more pronounced anode effect, while impedance results also indicated successful adsorption of the PFOA species on the steel surface.Laser confocal scanning microscope studies give the evidence that corrosion resistance of the treated samples improved compared to the untreated samples.Molecular simulation technique was used to confirm the ability of PFOA to decrease corrosion.The 150 g/L concentration of PFOA showed the most significant improvement in the anticorrosive property.
