Investigation and Solutions of Localized Corrosion of Copper Metallurgies in Industrial Recirculating Cooling SystemsCopper metallurgies are often chosen for heat exchanger material due to their improved heat transfer properties and nobility towards corrosion over a wide range of conditions. To prevent corrosion, it is the industrial standard to feed a nitrogen containing molecule typically featuring an azole group. This includes the use of benzotriazole and substituted benzotriazoles. Despite the addition of these film forming chemistries, there are environmental
