Galvanic Series of Metals

Galvanic corrosion is a natural phenomenon that occurs when two different types of metal are in contact with each other.


Basic Theory of Metallic Corrosion

Why do metals corrode and is there anything that can be done to prevent this from happening? Learn more about this natural phenomenon and the methods used to protect valuable metal structures.


Basic Theory of Electricity

Understanding electricity is a prerequisite for understanding how and why metals corrode. Learn more about the basics of electricity, voltage, current, and resistance.


Impressed Current Cathodic Protection

What is the difference between a Sacrificial Anode and Impressed Current Cathodic Protection system? Learn about when an Impressed Current Cathodic Protection system is needed and the types of structures it can protect from corrosion.


Sacrificial Anode Cathodic Protection

Galvanic corrosion occurs when one metal causes corrosion in another metal because of differing potential voltages. Learn more about how a Sacrificial Anode Cathodic Protection system takes advantage of this natural phenomenon to prevent corrosion in valuable metal structures.
