Corrosion Science and Engineering

At the end of this course, the students should be able to: 1. explain the basic concept of corrosion and socio-economic implication; 2. describe the fundamental causes of corrosion problem and failures; 3. explain the thermodynamics and kinetics of electrochemical reactions in corrosion of metals and alloys; 4. describe the various forms of corrosion (from uniform to localised to stress corrosion phenomena); 5. use Pourbaix and Evans diagrams as tools to predict corrosion; 6. discuss corrosion rate measurements using weight loss method and other methods; and 7. discuss the protection systems used to combat corrosion, including inhibitors, coatings and cathodic protection.

The course is aimed at investigating the underlying fundamental causes of corrosion problems and failures. Emphasis is placed on the electrochemical reactions occurring and the tools and knowledge necessary for predicting corrosion, measuring corrosion rates, and combining these with prevention and materials selection.
