Abstract

The behaviour of 70/30 Cu-Ni alloy in 3%NaCl medium, both pure and contaminated by 1 ppm S^2- ions, has been studied in the absence and in the presence of aminotriazole at a concentration of 10^-4M. Potentiodynamic and electrochemical impedance measurements showed that sulphides accelerate the corrosion of the alloy in 3%NaCl. The aminotriazole inhibited both anodic and cathodic corrosion processes. The inhibiting effect was higher when the solution contained the S^2- ion Analysis by scanning electron microscopy (SEM) showed that the inhibitor acts by establishing a very thin film on the metal surface. This film behaves as a barrier to the diffusion of dissolved oxygen and to the transport of the metal ions from the melt to the solution.

<EA>The behaviour of 70/30 Cu-Ni alloy in 3%NaCl medium, both pure and contaminated by 1 ppm S<sup>2-</sup>
 ions, has been studied in the absence and in the presence of aminotriazole at a concentration of 10<sup>-4</sup>
M. Potentiodynamic and electrochemical impedance measurements showed that sulphides accelerate the corrosion of the alloy in 3%NaCl. The aminotriazole inhibited both anodic and cathodic corrosion processes. The inhibiting effect was higher when the solution contained the S<sup>2-</sup>
 ion Analysis by scanning electron microscopy (SEM) showed that the inhibitor acts by establishing a very thin film on the metal surface. This film behaves as a barrier to the diffusion of dissolved oxygen and to the transport of the metal ions from the melt to the solution.</EA>
