Course content, instructors and details subject to change. This listing was last updated on March 1, 2013.

Date/Time: Sunday, May 5, 2013, starting at 8:00 a.m. For details, see course agenda

Course Chair & Instructor: Tom Glasgow, ASM International Instructor

Course Description: Curious about corrosion?  You should be. Corrosion destroys about 400 billion dollars of value in the U.S. each year and a proportionate amount in all other countries. It is costly, dangerous, wasteful, and often unsightly. It is at work in your business, your home, your auto, and your yacht.  Environments in which corrosion occurs range from moist air to salt water , from pipe lines to airlines, and possibly within the concrete of the bridges in your daily commute.

In this short course you will learn about the major forms of corrosion and the driving forces behind corrosion. Understanding the driving forces is the beginning to limiting or even avoiding the damage and danger corrosion presents. You will become familiar with the terminology needed to employ the provided textbook, allowing you to solve problems well beyond those covered in class.

Instructor Biography: Mr. Glasgow served most of his professional career as a research scientist and manager in materials science at NASA’s John Glenn Research Center. He is author of more than 40 technical papers in the field of materials science with interests in powder metallurgy, solidification processing, corrosion, and technology transfer. . He is a Fellow of the American Society for Metals International and teaches some of their professional development classes, for which he has been recognized via the Cleveland Chapter’s “Technical Educator of the Year” award. He is a recipient of an I-R 100 award for the development of oxide dispersion strengthened superalloys and is an inventor of the new material of choice for hydrogen cooled rocket engine thrust chambers as well as a new technology for characterizing three-dimensional fluid flows.

Introduction: overview of the course day.

Corrosion as an Electrochemical Phenomenon: Aqueous corrosion occurs by two simultaneous reactions, one an oxidation, the other a reduction. Appreciating that the two are connected by transfer of electrons is the basis of corrosion control.

General or Uniform Corrosion: The most costly but least dangerous form of corrosion. Like all other forms, one may protect against general corrosion. Unlike other forms, it is relatively simple to plan for its attack.

Pitting Corrosion: Often observed on corrosion resistant alloys. These alloys have a special protection mechanism, passivation. Unfortunately local ruptures lead to localized severe problems.

Concentration Cell Corrosion: A surprising change in the electrolyte chemistry in occluded regions causes flanges to leak.

Galvanic Corrosion: As familiar as your flashlight battery, this form of corrosion could destroy your auto engine in the absence of corrosion inhibitors.

Stress Corrosion Cracking: Materials may exhibit rapid failure, fracturing in just a few hours, when exposed to specific environments.

Erosion Corrosion: Most commonly observed in rapid liquid flows, subtle electrochemical means have been shown to offer protection.

Intergranular Corrosion: Metals are crystalline, each crystal meeting others at grain boundaries. The boundaries may be significantly different in composition than the grain interiors, setting the stage for destruction.

Dealloying: Because corrosion is an atomic scale phenomenon, the corrosion process may remove one species of atom preferentially, leaving a leaking porous pipe behind.
