ETHYLENEDIAMINE AS A CORROSION INHIBITOR OF 304 AND 316 AUSTENITIC STAINLESS STEELS IN ACIDIC MEDIUM
Austenitic stainless steels are widely used in the industrial environment because of their good mechanical properties and their resistance to corrosion. However, in highly corrosive media, such as in the presence of chloride ions, these steels have a susceptibility to some corrosive processes, such as pitting and intergranular corrosion. Corrosion inhibitors are generally used to reduce corrosive processes. Organic compounds containing amino group, double bonding, aromatic ring or compounds with N, O and S commonly exhibit corrosion inhibiting capability. In this work, the application of ethylenediamine as corrosion inhibitor of steels 304 and 316 in acidic medium was evaluated. It was observed that the compound showed corrosion inhibition at all concentrations studied. Nevertheless, the highest corrosion efficiency was observed for the highest concentrations.
