We are reliant on metallic structures to support our everyday activities, be it getting to work, transporting goods around the world, or storing and preserving food. Metals are everywhere.
However, from the moment most metals come into contact with water, they are subject to sustained and continuous attack which can lead to the metal corroding and failing to do its job.
It is therefore important to understand when corrosion will occur, how fast it will proceed and what can be done to slow down or stop it. Whether or not corrosion occurs at all is dependent on thermodynamics and is covered in the The Nernst Equation and Pourbaix Diagrams.
How to predict and control the rate of corrosion is covered in this TLP.
