Abstract

Corrosion inhibition effect of NaNO2, monoethanolamine & their mixture on steel G105 & N80 in seawater medium from Vung Tau offshore were measured by electrochemical method. The inhibitor mixtures with various concentrations were investigated. The inhibition efficiency of the mixture is higher than 90% in comparison with approximetly 60% for MEA and 70-80% for NaNO2 at the same concentrations. Besides, sone kinetic aspects for corrosion process of these steels in sea water were also studied and discussed.
