SURFACE AND INTERFACE ENGINEERING - 2020/1
Module code: ENGM295
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
A lecture and tutorial based module building upon previous materials engineering modules which provides greater depth in the specific area of important surface and interface related processes for engineers.
The initial part of the module will introduce/recap important fundamental knowledge regarding atomic structure, bonding, crystal structure and microstructure of materials. This will be followed by an introduction to the most important materials characterisation techniques to determine surface and sub-surface chemical composition, morphology and crystal structure.
The remaining parts of the module describe surface and interface based topics important for engineers, namely corrosion and oxidation, adhesion, organic coatings and wear. For each topic, the following will be addressed: (i) fundamental concepts; (ii) processes to modify the surface enabling reduced degradation, enhanced adhesion or surface functionalisation; (iii) chemical and mechanical test methods; (iv) case studies. There will be a 2 hour laboratory session to embed knowledge on the principles and operation of important materials characterisation techniques. There will also be 2 hours of lectures from industry experts, giving further case studies and underlining the importance of knowledge and understanding of corrosion, wear and adhesion in an industrial engineering context.

|Assessment type||Unit of assessment||Weighting|
The assessment strategy is designed to give students the opportunity to demonstrate:
The summative assessment for this module consists of:
• Assignment [learning outcomes 1 and 2]; 15 hours (25 %)
• Examination [learning outcomes 2, 3 and 4]; 2 hours (75 %)
Formative assessment and feedback
- • To build upon the year 3 modules on material selection and process-structure-property relationships of materials to provide in-depth knowledge and understanding of surface and interface related topics, namely corrosion, wear and adhesion important for engineering applications.
- • To explain the reasoning behind the selection of specific materials characterisation techniques for determination of chemical composition, surface morphology and (micro)structure of materials.
- • To describe the rationale underpinning the selection of materials, processes and methodologies to reduced wear and corrosion and enhance adhesion for different environments and applications.

Methods of Teaching / Learning
The learning and teaching strategy is designed to provide students with:
(i) an understanding of the capabilities of different materials characterisation techniques
(ii) knowledge of the fundamental principles underpinning corrosion, wear and adhesion processes
(iii) the ability to assess a mechanical system and select appropriate materials and processes to minimise wear and corrosion or maximise adhesion yielding enhanced performance and lifetime for specific engineering applications.
This is principally achieved through lecture and tutorial classes. In the initial 6 weeks, the degree of learning is evaluated through a summative assignment.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
