| Course Description: | This course is designed to provide
an understanding of the principles and methods used to minimize and prevent
corrosion. Metals and alloys are emphasized because these are the materials
in which corrosion is the most prevalent. Aqueous environments are also
emphasized because these are common corrosion conditions.
In the first half of the course, the impact and electrochemical nature
of corrosion are described, and then the corrosion fundamentals (electrochemical
reactions, phase (pourbaix) diagrams, aqueous corrosion kinetics, passivity,
and high-temperature oxidation) are emphasized. The forms of corrosion
(galvanic, pitting and crevice, environmentally induced cracking) and
corrosion prevention (protection methods) are accentuated in the second
half. Corrosion in the human body (for example, surgical implants and
prosthetic devices) and in other selective environments (concrete, seawater,
and water solutions containing dissolved salts, sulfur, and bacteria)
are also described in the second half. |
