Description
The first objective of this work is to study the short and long term effects of chloride and dissolved inorganic carbon (DIC) on copper corrosion rates using simulated and real drinking waters. The effects of chloride and DIC were evaluated in the presence and absence of ortho-phosphate, a commonly used corrosion inhibitor, and free chlorine residual, at pH values 7 and 8.5. A comparison between the rate of leaching and the instantaneous corrosion rates (quantified by corrosion currents) is presented. X-ray diffraction studies were also carried out on the exposed coupons to further interpret the results of the polarization and leaching experiments. Another objective of the study is to evaluate the stability of an artificially synthesized Cu2O film, under the influence of a number of synthetic and real waters, using Electrochemical Impedance spectroscopy. The performance of the artificial film as an inhibitor was studied and compared to that of a naturally formed heterogeneous scale, under specific water quality conditions.
