Course Description
The course will begin with emphasis on the importance of studying environmental degradation of materials. Fundamentals of environmental degradation of materials will be addressed beginning with thermodynamics and kinetics of electrochemical phenomena. Different forms of corrosion related to materials, environment and stress will be familiarized. Corrosion occurring in major environments will be treated. Experimental methods to assess and predict the rate of corrosion will be introduced. Fundamentals of high temperature oxidation of metals will be treated. This will be followed by principles and methodology of corrosion control. Degradation of various material classes such as polymers, composites and electronic materials will be discussed. In the end, future outlook in this important field of engineering will be presented.
