Abstract

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.

Özet

Bu çalışmada yapay deniz suyunda Cu-10 % Ni bakır-nikel alaşımının erozyon-korozyon davranışı incelenmiştir. Erozyon-korozyon testleri farklı hızlarda dönen silindirik elektrot kullanılarak gerçekleştirilmiştir. Denemelerde serbest korozyon potansiyeli, anodik polarizasyon, elektrokimyasal impedans analizi, ağırlık kaybı testleri ve optik mikroskop incelemesi yapılmıştır. Dönme hızı ve zamanın artması ile yapay deniz suyundaki Cu-10 % Ni alaşımının korozyon hızı artmıştır. Koruyucu yüzey filmindeki hasarın, dönme hızı 1600 d/d olduğunda 3. saatten itibaren, 2000 d/d olduğunda ise 1. saatten itibaren başladığı ve giderek arttığı belirlenmiştir.
