When two different metals are in contact and exposed to moisture containing salts or pollutants, one of the metals can experience accelerated corrosion while the other remains protected. This type of accelerated corrosion between dissimilar metals negatively impacts the overall corrosion protection of the project and is referred to as galvanic corrosion, bi-metallic corrosion, or dissimilar metal corrosion. It can be prevented by utilizing compatible metals and/or favorable surface area ratios, providing barriers to break electrical contact between metals, or isolating the metals from the environment.
