1 MODULE DESCRIPTOR TITLE Degradation and Surface Engineering SI MODULE CODE S CREDITS 10 LEVEL 6 JACS CODE H100 SUBJECT GROUP Materials Engineering DEPARTMET Engineering & Mathematics MODULE LEADER M.D.Bramhall OTIOAL STUD HOURS B TPE Tutor-led Tutordirected Selfdirected Total Hours MODULE AIM(S) (i) (ii) (iii) (iv) To enable the student to develop a systematic approach to the description of surfaces of common engineering metallic alloys, polymers, concrete and wood. To develop further understanding of the processes of of materials under ambient atmospheric conditions, exposure to aqueous environments, gaseous environments and in the case of polymers exposure to UV radiation or high temperature. To develop understanding of the modes of failure exhibited by material subject to adverse demand and physical environments. To appreciate the methods by which the performance of engineering components can be enhanced using surface engineering processes. MODULE LEARIG OUTCOMES By engaging successfully with this module a student will be able to: (i) (ii) (iii) (iv) (v) Describe the physical and chemical condition of engineering surfaces and the modification to material microstructures by surface treatments or. Identify the mechanism of wear and relate these to the properties of the material being considered. Appraise the suitability of materials for use in elevated temperature and aqueous environments, and in-service monitoring techniques. Appraise the various surface hardening processes and to analyse the mechanism of each in terms of structural change and relevant transfer process. To appraise the properties, technical and economic factors, that affect the use, choice and performance of coatings and methods used to apply them.

2 IDICATIVE COTET A. Degradation. Study of the following types of material process. Surface Integrity, Surface Removal, Residual Stress, Topography, Wear Mechanisms and the interaction of physical wear, microwelding and erosion. Aqueous (wet) corrosion in terms of Electrode potentials. The ernst Equation, Electrochemical cells and inhibitors. The effects of stress, and corrosion in terms of stress corrosion, corrosion fatigue, hydrogen assisted cracking. Prevention techniques such as cathodic protection and paint systems will be included. Atmospheric corrosion in terms of humidity, pollution (SO 2, O 2 ) and film formation. The effects of high temperature dry oxidation on oxide film volume, and protectiveness. The corrosion of steel in reinforced concrete and its manifestation and avoidance. The weathering on non metals, cracking of polymers, and of stone and ceramics will be studied. B. Surface Engineering Thermal treatments, surface hardening of alloys, carburising, nitriding and carbo-nitriding, metallic coatings. Processes such as induction hardening, laser hardening, CVD, PVD, will be discussed. The diffusion processes involved in chemical treatment. Wet processes such as electroless, electroplating and anodising will be studied. Organic coatings such as paints, PTFE, PVC. LEARIG AD TEACHIG METHODS Students will be supported in their learning, to achieve the above outcomes, in the following ways: Teaching will be by means of lectures, tutorials and practicals. Guest lecturers will be used where appropriate to bring in current research expertise. Students will keep a weekly reflective journal of lectures and supporting activities, whilst working on a group case study. ASSESSMET STRATEG AD METHODS Tas k o.
