Course content

This course is equal to TMT4255 Corrosion and Corrosion protection.

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 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. Corrosion Management including corrosion monitoring

Learning outcome

The candidate has knowledge about:
- The theoretical fundament for why corrosion initiates on metallic materials in water containing electrolytes including thermodynamic, electrode kinetic, mass transport and passivity.
- Different types of corrosion.
- Different methods to reduce the probability for initiation of corrosion.
- Corrosion Management including corrosion monitoring.

The candidate can:
- Construct a Pourbaix diagram and explain how to use it.
- Calculate corrosion rate for a metal under defined conditions.
- Differ between and describe characteristic features with different corrosion forms; uniform, galvanic, pitting, crevice and stress corrosion cracking.
- Propose different types of corrosion protective coatings for a structure.
- Calculate number of anodes to protect a structure.
- Select corrosion monitoring method(s) for defined applications

General competence:
The candidate can:
- Participate in a failure analysis group for a component with knowledge about corrosion.
- Propose alternative materials or alternative ways to prevent corrosion for a new component or a production unit.
- Knowledge about elements in a Corrosion management system.

Learning methods and activities

Lectures, problem sets, laboratory work and semester project. Solutions to selected problem sets and assignments have to be found satisfactory to qualify for the final examination. The lectures are normally given in English. If the course language is English the examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.

Compulsory assignments

  • Exercises

Further on evaluation

At postponed exam written exam can be replaced with oral examination.

For a re-take of an examination, all assessments during the course must be re-taken.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
