Copper corrosion in distribution systems: evaluation of a homogeneous Cu2O film and a natural corrosion scale as corrosion inhibitors

The aim of this work is to assess the performance of different corrosion scales as effective copper corrosion inhibitors using synthetic waters and distribution system waters. The major objective of the study was to evaluate the stability of an artificially synthesized Cu2O film and naturally formed heterogeneous corrosion scales under the influence of a number of synthetic and real waters, using Electrochemical Impedance Spectroscopy (EIS)....
