In the realm of infrastructure maintenance and management, corrosion stands out as a persistent and insidious adversary, capable of silently undermining the integrity of critical assets over time. The consequences of neglecting corrosion prevention can be severe, ranging from structural failures to economic losses and environmental impacts.

Galvanic corrosion occurs when two dissimilar metals come into contact with each other in the presence of an electrolyte. This type of corrosion is distinguished by the rapid corrosion of one metal while the other remains relatively unaffected.
