How do artists mitigate galvanic coupling when attaching aluminum plaques to cast iron animal sculptures?

Artists often face the challenge of galvanic coupling when attaching aluminum plaques to cast iron animal sculptures, as these dissimilar metals can cause corrosion over time. To mitigate this issue, several techniques are employed. One common method is using insulating materials like rubber or plastic gaskets to separate the metals, preventing direct contact. Another approach involves applying protective coatings, such as paint or powder coating, to both surfaces to reduce electrochemical reactions. Additionally, artists may opt for stainless steel fasteners instead of regular steel to minimize galvanic corrosion. Proper sealing and regular maintenance also play a crucial role in preserving the artwork. By implementing these strategies, artists ensure the longevity and aesthetic integrity of their metal sculptures.
