Abstract

The present study is aiming to study the effect of sulfuric acid diamide (SAD) on corrosion of bronze CuSn8. In order to determine the optimal corrosion inhibiting effect, SAD was tested at different concentrations. The inhibiting effect of the SAD was investigated by electrochemical methods, in a 0.2 g / L Na₂SO₄ + 0.2 g / L NaHCO₃ (pH = 5) solution simulating acid rain. The results show that SAD exerts a good protection in case of CuSn8.
