Application of Anodes in Marine and Defense Industries

The outer components of marine and defense vessels are constantly being threatened by the surrounding water. Over time, corrosion can lead to a loss of integrity in the structure, hence the use of marine anodes.

Understanding Corrosion

Most metals immersed in water are subject to rust and disintegration caused by electrochemical corrosion. Marine anodes are designed to fight electrochemical corrosion by using the process of galvanic corrosion.

Essentially, galvanic corrosion is caused by placing less-active metals near highly active metals. The process requires the active metal to “sacrifice" itself, attracting the galvanic corrosion to it while protecting the critical components. In this instance, the sacrificial active metal acts as the anode, and the valuable metal the cathode.

Marine Anode Optimization

Anodes aren’t meant to last forever – their purpose is to absorb natural wear, thus protecting surrounding valuable metals from the threat of corrosion.
