What type of anodes are used to mitigate galvanic anode dissipation?

The use of ICCP (Impressed Current Cathodic Protection) anodes is particularly effective in mitigating galvanic anode dissipation because these anodes utilize a continuous current provided by an external power source to protect metal structures from corrosion. Unlike sacrificial anodes, which rely on the inherent galvanic action between dissimilar metals, ICCP systems can maintain a more consistent and controlled level of protection. This approach is advantageous in situations where environmental conditions can change, ensuring that sufficient protective current is delivered to combat corrosion more effectively.

In contrast, sacrificial anodes, which are commonly used in galvanic systems, can become exhausted over time and may not provide sufficient protection if the rate of corrosion is high. Inert and reactive anodes also have specific applications but do not effectively address the dissipation issues linked to galvanic anode systems in the same way as ICCP anodes do. Thus, the control and reliability offered by ICCP anodes highlight their suitability in mitigating galvanic anode dissipation.
