Inhibition Pitting Corrosion of A-890-1B Stainless steel in NaCl Solution by 5-amino-1,3,4-thiadiazole-2-thiol

Guzman, M.; Lara R.

Abstract

The pitting potential of ASTM A-890-1B stainless steel at different sodium chloride activities and constant temperature was studied. As sodium chloride activity increases, the pitting potential decreases, favoring localized corrosion. In addition, the effect of different 5-amino-1,3,4-thiadiazole -2- thiol concentrations at a 3.5% NaCl concentration and constant temperature was assessed, showing that the greater the inhibitor concentration, the greater the pitting potential. In the same way, the pitting potential decreases as temperature increases in NaCl constant concentration.
