Corrosion is the most common form of metal degradation leading to product failure. Understanding how corrosion occurs and how to prevent it from occurring is critical to designing products that function as required over their entire life.

You should take this course if you make design decisions involving metal corrosion or need to be able to identify specific corrosion mechanisms when corrosion occurs.


Approximately 6 hours of instruction divided into 10 easily manageable modules.

Participants can access the course 24/7 from any computer with an internet connection.
