Abstract

The electrochemical behaviour and inhibitor protection of 2�amino�5�ethyl�1,3,4�thiadiazole (TTD) on the pitting corrosion of austenitic stainless steel (type 304) in dilute sulphuric acid solution con� taminated with recrystallised sodium chloride was evaluated with the aid of potentiodynamic polarization method. TTD greatly reduced the corrosion rate of the steel with a corrosion inhibition efficiency ranging from 88.99–87.36%. The corrosion potential, pitting potential, repassivation potential, nucleation resis� tance, passivation range and repassivation capacity measurements and potentiodynamic studies were applied to assess the steel’s pitting resistance characteristics and behaviour in the acid chloride media. Results showed that pitting potential values increased with addition of TTD compound in conjunction with increase in the passivation range which strongly indicating increased electrochemical resistance to pitting corrosion
