Leerdoelen At the end of the course, the student is able to:
1) relate the surface and mechanical properties to the contact pressures and can explain its influence on the mechanisms of friction and wear of metals, polymers and ceramic materials.
2) solve problems related to the friction coefficient and wear rate under different lubricating conditions
3) explain various aspects of orthopedic, oral, ocular, skin and tactile tribology and relate them to diseases like arthritis, xerostomia, dry eyes and Sjögren's syndrome.
4) assemble and present information on a tribological or biotribological topic.
Omschrijving Tribology is the science of friction, wear and lubrication at a rubbing (articulating) interface between two surfaces. Proper lubrication can provide protection against high friction, which causes energy loss and wear, which causes material loss. The biological world specially the human body has solved both the problem of friction and wear with the help of unique tissues, fluids and anatomical design. Basic concepts of tribology will be understood using the knowledge from the field of engineering tribology and then the wonderful world of biotribology will be explored. Relation of biotribology to human dysfunction like arthritis, xerostomia and dry eyes will be elaborated.

This course will thus cover the following aspects
I. Engineering Tribology
1. Nature of engineering surfaces.
2. Strength and deformation of solids, adhesion and contact between non conformal surfaces.
3. Friction in dry and wet conditions.
4. Wear and wear mechanisms for ceramics, metals and polymers.
5. Lubricant properties and chemistry.
6. Hydrostatic, hydrodynamic lubrication.
7. Elastohydrodynamic and Boundary lubrication.
II. Biotribology
8. Natural articular joint tribology.
9. Artificial joint tribology.
10. Oral tribology and salivary lubrication.
11. Ocular tribology.
12. Skin and tactile tribology.
