MECH 5390M Tribology and Surface Engineering

This module is not approved as an Elective

Module summary

Tribology is the study of Friction, Lubrication, and Wear. But more importantly it is the study of how engineering materials interact at the surface. The success of engineered systems will often depend on these interactions. Cars need lubricated engines, prosthetic joints need to not wear out, aircraft need lubrication from the landing gear to the bearings in a jet engine.The module will provide a broad introduction to the fundamental concepts and study of tribology, introducing topics such as real surfaces, friction and friction models, wear and fretting, and lubrication.

Objectives

With a strong foundation delivered through in-person lectures and guest seminars the application of tribology and its current challenges will be introduced across the Mechanical, Medical (Biotribology), Automotive, and Aeronautical engineering disciplines.

Learning outcomes
1. Analyse and evaluate the key concepts of tribology: Friction, lubrication, and wear
2. Develop an appreciation for how real surfaces interact in engineered systems
3. Apply engineering theory to a range of real problems (Hertzian analysis, characterisation of surfaces, laws of friction, wear mechanisms, lubrication regimes)
4. Evaluate tribological challenges across multiple engineering disciplines
5. Measure key tribological parameters in a lab setting.

Upon successful completion of this module the following UK-SPEC learning outcome descriptors are satisfied:
A comprehensive understanding of the relevant scientific principles of the specialisation (SM1m, SM7M)
Knowledge and understanding of mathematical and statistical methods necessary to underpin their education in their engineering discipline
and to enable them to apply a range of mathematical and statistical methods, tools and notations proficiently and critically in the analysis and
solution of engineering problems (SM2m)
Awareness of developing technologies related to mechanical engineering (SM4m)
Understanding of engineering principles and the ability to apply them to undertake critical analysis of key engineering processes (EA1m)
Ability both to apply appropriate engineering analysis methods for solving complex problems in engineering and to assess their limitations
(EA6m, EA6M)
Awareness that engineers need to take account of the commercial and social contexts in which they operate (EL2, EL9M)
Advanced level knowledge and understanding of a wide range of engineering materials and components (P2m, P12M)
Understanding of the use of technical literature and other information sources (P4)
Apply their skills in problem solving, communication, information retrieval, working with others, and the effective use of general IT facilities (G1)

Methods of assessment

Coursework

Assessment type	Notes	% of formal assessment
In-course Assessment	MCQ Test Formative	0.00
In-course Assessment	MCQ Test Formative	0.00
Practical	Production and analysis of friction/wear data to be submitted as a report	40.00
Total percentage (Assessment Coursework)		40.00

10% of the practical marks are associated with having completed the laboratory, and 90% of the marks are allocated to the analysis of the results in the lab report. Resit students do not have to retake the laboratory if they’ve already done this and will only need to submit a new analysis report.

Exams

Exam type	Exam duration	% of formal assessment
Standard exam (closed essays, MCQs etc) (S1)	2 hr	60.00
Total percentage (Assessment Exams)		60.00

Normally resits will be assessed by the same methodology as the first attempt, unless otherwise stated
