Evaluation of Wash Inhibitors for Metals Exposed to Marine Environments

The effectiveness of wash inhibitors was evaluated using weight-loss method.The scanning electron microscopy(SEM) and X-ray energy dispersion spectroscopy(EDS) were employed to investigate the inhibition behaviors of inhibitor ADD5 for 907A and 921A steel.It was found that the inhibitors ADD4,ADD5 and ADD10 had good anti-corrosion property. Sticks were symmetrically formed on the surface of 907A and 921A steel and these sticks could suppress the corrosion reaction.
