An Introduction to Cathodic Protection Principles

COURSE NO: E05-006
PDH CREDIT: 5
An Introduction to Cathodic Protection Principles
Course Highlights

This online engineering PDH course will provide you with an introduction to the principles of cathodic protection for underground and underwater structures.  You will be introduced to the physics and chemistry of the corrosion process and how to mitigate the corrosion using cathodic protection techniques.

 

Understanding the principles of cathodic protection systems is based upon understanding the nature of the corrosion process.  The corrosion of metals is an electrochemical process.  That is, it is an electrical circuit where the exchange of electrons (electricity) is conducted by chemical reactions in part of the circuit.  These chemical reactions occur at the surface of the metal exposed to the electrolyte.

 

Cathodic protection is the prevention of corrosion by making a metal, which would ordinarily behave like an anode and corrode, behave like a cathode and be free from corrosive attack. Essentially, cathodic protection is predetermining the anode in the corrosion cell, or making a large corrosion cell to overcome the other smaller corrosion cells.

 

This 5 PDH online course is intended for civil engineers, structural engineers, mechanical engineers and other design and construction professionals seeking an introduction to the principles of cathodic protection.
