Course Description

Understand the fundamental mechanisms of wear, friction and lubrication.

Be able to make predictions of the risk of wear of two surfaces in contact.

Be able to suggest suitable materials and lubricants for different applications.

Have obtained a first experience of solving tribological problems.

Course Objectives

Tribological losses due to wear, friction and bad lubrication cause enormous costs every year.

1. This course will make engineers aware of these problems and learn how to avoid

     them in an early stage.

2. The following content will be covered:

• Wear processes

• Friction

• Lubricants

• Lubrication

• Machine component tribology

• Surface roughness

• Tribo testing

3. Surface Coatings to minimize  the wear of the tools

4. Crystallographic effect on the wear mechanisms

Course Learning Outcomes

At the end of this course, students will have a complete understanding of the following fundamental topics in engineering:

I. Explain the different wear processes in contacts between metallic, ceramic and

polymeric surfaces

II.Explain the processes of lubrication in all regimes

III. Explain the friction phenomena

IV. Select a suitable lubricant for a specific application

V. Select a suitable material combination for tribological contacts

VI. Determine the risk of wear by using simple analyses

VII. Suggest an explanation to the cause of a tribological failure

VIII. Design a wear & friction test

IX. Obtain further experience of teamwork, writing reports and oral presentations
