Coatings - Corrosion Theory and Protection
Overview
Corrosion is defined as the deterioration of a material,
usually a metal, because of a reaction with its environment and which requires
the presence of an anode, a cathode, an electrolyte, and an electrical current.
The annual cost of corrosion and corrosion protection in the U.S. is estimated
to be in the billions of dollars. Corrosion can be mitigated by five basic
methods: coatings, cathodic protection, materials selection, chemical
inhibitors, and environmental change. It is important that the engineer
understands the causes and forms of corrosion, as well as the available
protections, to ensure that the most cost effective corrosion mitigation method
is employed for each application.
In this course, the student will study the causes and forms
of corrosion and the methods available for providing corrosion protection. The course will cover Chapter
2, "Corrosion Theory and Protection" in
the US Army Corps of Engineers document EM 1110-2-3400, "Painting: New
Construction and Maintenance".
The student must take a multiple-choice quiz consisting of
ten questions at the end of
this course to obtain PDH credits.
