Course content

Corrosion, erosion, wear and fatigue are central mechanisms for damaging a surface and thereby the integrity of a structure. Tribology is the science of interacting surfaces in relative motion. This course deals with the most central topics within tribology and degradation mechanisms, and describe how to modify the surface and/or to use lubricants to achieve desired lifetime of a component. Focus will be set at different types of coating (organic, metallic, ceramic) and direct surface modification in addition to lubrication. Testing and inspection methods will be introduced and discussed, as well as the economical aspect.

Learning outcome

The students shall be able to prepare a requirement specification for modification of a surface with the aim to avoid degradation or achieve the required surface finish. Based on this requirement specification the students shall be able to select the most optimal solution including description of requirement to surface preparation, application and pre-treatment.
In addition the students need to understand what tribologi is including which elements and how these elements influence the tribological properities of a surface.

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 when students who do not speak Norwegian take the course. If there is a re-sit examination, the examination form may be changed from written to oral.
