    One of the first thing that comes to your mind after hearing the term “corrosion” is corrosion of a metal. Corrosion is a basically harmful phenomenon, but it can be useful in some cases. For instance, environment’s pollution with corrosion products and damage to the performance of a system are among its harmful effects, whereas electric energy generation in a battery and cathodic Cited by:

An intermittent impressed current cathodic protection technique using photovoltaic energy was evaluated to determine it`s ability to protect bridge concrete piles in marine environments against corrosion. The technique uses commercially available anode systems to deliver the cathodic protection current to the concrete and onto the reinforcing.

Takeaway: Commonly used to protect numerous structures such as pipelines, ships, tanks and offshore oil platforms, cathodic protection works by allowing a more reactive, sacrificial metal to corrode instead of the protected metal.
