Corrosion of copper is a significant issue in many industries, and understanding its mechanisms is crucial in mitigating its effects. In this study, we investigated the corrosion of copper on our campus by examining door plates, pipes, and fittings. Our findings indicate that cuprite is the initial corrosion product that forms on copper surfaces. Furthermore, we observed bluish-green products on the door plates, which confirm patination on the copper surface due to atmospheric exposure.

We also explored the occurrence of galvanic corrosion on a steel door at the screws and near the junction of the plate and the door. However, we found that the application of a barrier layer, such as paint or coating, can prevent and postpone galvanic corrosion. Additionally, we identified several types of corrosion that can occur in copper pipes, including erosion, crevice, and pitting. The fittings and joints were particularly susceptible areas to corrosion in copper pipes.

Overall, our study provides valuable insights into the corrosion of copper in various settings on our campus, and our findings could aid in the development of effective corrosion prevention strategies. By understanding the mechanisms and types of corrosion that can occur in copper, we can better protect and maintain the integrity of copper-based systems and infrastructure.
