Mechanism of copper patina formation in marine environments

Abstract

Data analysis of the initial superficial layers of copper patina formed in several marine environments, using X-ray diffraction and cathodic reduction techniques, are presented. It was observed that cuprite phase decreases and the paratacamite phase increases, as corrosion develops on the surface of copper. The data presented show good agreement with previously published eletrochemical reactions of copper corrosion in marine environments.
