After the course the student is able to,|
1. Explain / describe the basics of friction and wear of dry and lubricated systems.
2. Select the materials in contact as a function of the operational conditions.
3. Select dry and lubricated contacts for high tech systems.
4. Predict friction and load carrying capacity of (lubricated) contacts
5. Evaluate if a construction, from a tribological point of view, is properly designed.
The overall course aim is to apply some basics of mechanics, fluid dynamics and material science to the field of tribology (friction, wear and lubrication).
The course Tribology gives a general overview of tribology for dry and lubricated systems. The basic friction laws for the dry contact situation are explained as well as the four main wear mechanisms (fatigue, adhesive-, abrasive- and corrosive-wear). Next, the two lubrication mechanisms (hydrodynamic and hydrostatic) are discussed with respect to film formation and load carrying capacity. Thermodynamics of Tribology is also introduced. Most contents of the lectures are as given in the book J.A. Williams, “Engineering Tribology”, Cambridge University Press, 2005|
The lectures close with an assignment which results in a report that has to be defended during the oral exam.
