Corrosion Engineering

At the end of this course, the students should be able to: 1. explain in details what corrosion is; 2. discuss the socio-economic implications of corrosion and the need to prevent same in manufacturing processes, materials selection and surface finish; 3. describe the Pourbaix diagram and its application to corrosion prevention and control; and 4. develop the necessary skill on methods of corrosion control and prevention by inhibitors, surface coating and electroplating.

Two view points on corrosion: extractive metallurgy in reverse and electrochemical degradation of materials which is within the purview of physical metallurgy and electrochemistry; socio-economic implications of corrosion and need to prevent it; emphasis on the thermodynamics and kinetics of electrochemical corrosion of metals and alloys; description of metallurgical factors, effect of applied stress corrosion, cracking corrosion fatigue and passivity; methods of corrosion control and prevention including alloy selection, inhibitors, anodic and cathodic protection, coating and electroplating.
