Course Objective

The overall aim of the tribology course is to provide students with a general and useful introduction to the main concept and principles of Tribology (friction, Lubrication and wear), with particular emphasis on lubricated systems. It is regognised that the field of Thibology is very large and multidisciplinary and that it is thus impossible to cover all aspects of the subject adequately. Instead the Tribology Course focuses on those areas of Tribology particularly relevant to the design and performance of lubricated machine components. The course covers the underlying principles and provid an extensive set of handout notes and references aimed at assisting students comprehend and address tribological problems that they may meet in their future engineering careers, even those outside the areas directly covered by the Course.

Learning Outcomes of the Course Unit

1   Discuss - making appropriate use of technical terminology the main laws and concepts of Tribology and their historical development;
2   Explain the origins and characteristics of the main lubrication regimes and the machine components and conditions in which each is likely to be prevalent
3   Describe the main materials used in plain bearings, rolling element bearings and gears and the reasons for the materials being used;
4   Discuss the composition, specification and performance of liquid lubricants;
5   Identify the main types of tribologically-induced surface damage;
6   Deacribe the mechanisms and origins of the main forms of tribological damage, and of current ways of predicting the onset or accumulation of such damage
