Introduction to Cathodic Protection Design
Aleksander Andrzejewski, P.E.
Overview
The first use of a cathodic protection system
dates back to 1825 when Sir Humphry Davy used malleable iron in a series of
experiments to protect the copper clad ships of the Royal Navy. The iron served
as a sacrificial anode, thus protecting the copper cladding from deterioration.
Since that time, cathodic protection has remained the most effective method in
controlling corrosion and is commonly used on many types of structures, such as
pipelines, underground storage tanks, locks, and ship hulls. It reduces
corrosion by minimizing the difference in potential between anode and cathode.
This is achieved by applying a current to the structure to be protected from
some outside source.
This course introduces the student to the principles of both sacrificial and
impressed current anode systems. The merits of each type are described and
the process for designing each type of system is covered. Example problems
are provided which demonstrate how to design an anode system to solve "real
world" corrosion problems.
The student is required to
read and review the material contained in ARMY TM 5-811-7, Electrical Design,
Cathodic Protection.
The
student must take a multiple-choice quiz consisting of twenty (20) questions at the end of
this course to obtain PDH credits.
