Pourbaix Diagram for Copper: Understanding Corrosion Behavior
A Pourbaix diagram for copper depicts the stability regions of various copper species under varying pH and electrochemical potential conditions. It helps predict copper corrosion behavior by identifying areas where copper is immune, passive, or actively corroding. The diagram’s key features include stability regions for Cu metal, Cu2+ ions, and various copper oxides. By understanding these regions, engineers can assess the corrosiveness of different environments and develop strategies to prevent copper degradation, ensuring its longevity and performance in critical applications.
