| Abstract: | This paper describes a fundamental investigation of the corrosion behavior of copper-nickel alloy in cooling water environment, utilizing light optical, scanning electron microscopy and X-ray diffraction. The principal objectives of the research are to examine the fundamental mechanism of corrosion attack, and to study the effect of alloy composition and the water composition on the corrosion process.The work involves measurements of total weight loss and further information obtained by electrochemical monitoring.Finally,the measurements to prevent corrosion attack have been suggested. |
