Abstract

Sodium anthranilate (SA), sodium phenyl anthranilate (SPA), and benzotriazole (BTA) were tested as inhibitors of the early depassivation stages of Л70 α-brass in neutral chloride electrolytes. Although SA and SPA were found to initiate pitting corrosion at α-brass, the antagonism between SA (or SPA) and Cl− ions can result, at a certain ratio of their concentrations, in the inhibition of the pitting corrosion of α-brass. α-Brass was best protected from pitting by BTA.
