Course content
Electrochemical basis of corrosion: Thermodynamics, potential-pH diagram. Kinetics of corrosion reactions: Polarisation curves, mixed potential theory, passivity, effect of mass transfer. Types, causes and propagation of corrosion. Effect of metallurgical, mechanical, microbiological and environmental factors. Quantitative estimation of corrosion rates. Description of mechanisms for types of corrosion for different metal and environment combinations. Corrosion protection: Electrochemical methods, inhibitors, surface treatment, effect of material properties, materials selection, design. Corrosion properties of important construction materials. Test methods. Measurement and monitoring of corrosion.
Learning outcome
The course gives background for understanding various corrosion processes, protection methods and materials selection with practical examples. Based on the basic theory, the student shall learn to evaluate if corrosion can occur under specific operating conditions in a given equipment or construction. In cases where corrosion can occur, the student shall be able to determine the probable corrosion type, estimate the corrosion rate and propose the most reasonable protection method as regards safety, price and environmental considerations. The student shall be able to propose the correct materials, design and operation conditions to reduce the likelihood of corrosion in new equipment and constructions. The student shall also be able to propose necessary laboratory and field tests and take part in research programs to solve specific corrosion problems. The course also gives adequate engineering background for performing troubleshooting and corrosion monitoring. The course provides extensive teaching in corrosion theory and properties of important construction materials in the presence of corrosive environment. Students are trained in the application of the theoretical principles by solving research-based and applied problem sets, performing a laboratory project and writing a semester report on corrosion case studies.
Learning methods and activities
Lectures, group projects, problem sets, laboratory work. Solutions to selected problem sets and assignments have to be found satisfactory to qualify for the final examination. If the teaching is given in English the examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.
Compulsory assignments
- Problem sets
Further on evaluation
If there is a re-sit examination, the examination form may be changed from written to oral.
Recommended previous knowledge
Basic courses in chemistry, thermodynamics, physics and materials technology.
