| Summary: | In this study, the erosion-corrosion behaviour of Cu-10 % Ni copper-nickel alloy in artificial sea water has been investigated. The erosion-corrosion tests have been conducted using a cylindrical electrot rotating at different speeds. In the experiments, free corrosion potential tests, cycle polarization tests, electrochemical impedance spectrum (EIS) analysis, weight loss tests, and optic microscope observation were performed. The corrosion rate of Cu-10 % Ni copper-nickel alloy in artificial sea water increased with increasing rotation speed and time. It was also determined that the breakdown of the protective film began after 3 hours at the rotation speed of 1600 rpm, and 1 hour at the 2000 rpm, and grew with increasing time. |
