The scientific and applied corrosion literature has been reviewed in order to establish the state of the art knowledge on the general corrosion of copper. Based on the evaluation of electrochemical fundamentals of corrosion processes and the chemical composition of solid corrosion byproducts on internal pipe surfaces, major parameters that influence the general corrosion of copper are presented. The current mechanistic understanding and the existing approaches for mathematical modelling are also discussed. General corrosion of copper is a well studied topic, where major parameters have been identified. Future research should concentrate on secondary effects, such as the interaction of organic and inorganic water constituents, and how water treatment influences the physicochemical processes at the solid/liquid boundary.

Based on a literature study and experiments the copper corrosion mechanism is subdivided into three processes: copper oxidation, deposition of corrosion by-products, and establishment of a solubility equilibrium. This approach is applied to explain the results of a study on the influence of temperature on copper dissolution and deposition of copper corrosion by-products. Changes in water quality are monitored by regular sampling, qualitative and quantitative changes of surface layers are studied using computer-supported light microscopy and scanning electron microscopy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
