UNIQUE NUMBER: 17970/18370 INSTRUCTOR: PROFESSOR HAROVEL G. WHEAT ETC 5.202, 512-471-1451, [email protected] TIME: MWF 11:00 A.M.-12:00 NOON PLACE: ETC 2.114 OFFICE HOURS: MW 1:30-4:30 P.M. IN ETC 5.202 (AND BY APPOINTMENT) OBJECTIVES: This course provides an introduction to the principles of electrochemistry as well as the essential elements of electrochemical corrosion. This introduction is followed by development of the thermodynamic and kinetic aspects of electrochemistry, including potential-pH (Pourbaix) diagrams, mixed potential theory, and the theory and application of passivity. The goal is to provide a foundation for understanding the forms of corrosion, the mechanisms of corrosion, electrochemical methods to study and measure corrosion, and the principles and methods leading to mitigation of corrosion problems that might occur in engineering practice. COURSE DESCRIPTION: Corrosion principles; electrochemical, environmental, and metallurgical effects; types of corrosion; corrosion testing and prevention; modern theories: principles and applications. PREREQUISITES: Major sequence or approval by instructor/Graduate standing. TEXTBOOK: D.A. Jones, Principles and Prevention of Corrosion, 2nd edition, Prentice Hall, 1996.
