Sažetak
Copper-based alloys, such as the copper nickels are often used as corrosion resistant materials within the sea environment in manufacturing of tubes, heat exchangers and condensers on ships, desalinization equipments, etc. In spite of their excellent corrosion resistance, these alloys are known to suffer accelerated corrosion when exposed to flowing electrolyte. The effect of the Ni content in the Cu-Ni alloys (from 10-40 at.%) and the surface Cu-diethyldithiocarbamate films on the corrosion resistance of the materials in synthetic seawater under stagnant and flow conditions were investigated using electrochemical impedance spectroscopy. The results are discussed in terms of segregation of Ni ions in the barrier Cu(I) oxide and the stability of the inhibitor film.
