Course content

Corrosion, wear and friction are central mechanisms for damaging a surface and thereby the integrity of a structure or a component. Tribology is the science of interacting surfaces in relative motion. This course deals with the most central topics within surface protection and tribology.
The course deals with basic tribological mechanisms of component and construction failure. The knowledge gained in this course will help you in understanding how to achieve desired lifetime of a component or construction by application of basic tribological calculations (surface roughness, friction and lubrication), coatings, surface modification, wear phenomena and lubricants. Testing and inspection methods will be introduced and discussed, as well as the economical aspects of coating technologies.
The goal of the course is to give the students knowledge and skills in wear, friction, lubrication, lubricants, corrosion and surface engineering for meeting the needs of the industry in their future professional careers.

Learning outcome

Knowledge:
- phenomena happening when two surfaces come together into contact (friction, wear, elastic/plastic deformation, surface roughness).
- the most important surface degradation mechanisms (corrosion and wear).
- implications of surface degradation mechanisms for materials lifetime.
- the most important types of coatings and surface modifications for protection of surfaces against corrosion and wear.
- selection of surface treatments/coatings according to surface degradation mechanisms.
- Selection of lubricants and lubrication processes according to system function.

Skills:
- prepare a requirement specification for modification of a surface with the aim to avoid surface degradation or achieve the required surface finish.
- select the most optimal solution including description of requirement to surface preparation, application and pre-treatment.
- Understand the causes for surface failure when relative motion has been involved in a system.
- Understand the causes for surface failure when lubrication has been used in a system.
- Propose materials solutions for controlling wear and friction.

General competence:
- Understand how to chose surface protection depending on the environment where the construction/component is exposed, visual appearance, desired lifetime and other properties.
- Understand what tribology is, including what parameters that affect the tribological properties of a surface and how these can be improved.

Learning methods and activities

Lectures, teamwork and demonstrations. Students need a number of approved calculation and research exercises to access examination. The lectures and exercises are in English. The examination papers will be given in English only. Students are free to choose Norwegian or English for answering the exam.

Compulsory assignments

• Exercises

Further on evaluation

If there is a re-sit examination, the examination form may be changed from written to oral.

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