SESG6034 Surface Engineering

Module Overview

This module covers the aspects of surface engineering, to develop fundamental understanding and the role of materials to allow surface selection for mechanical contacts and their surrounding environmental conditions. The module will explore a range of surface treatments and advanced coatings that are designed minimise wear, friction and surface oxidation / corrosion. Applications and economics of surface treatments will be addressed by means of industrial case studies.

Aims and Objectives

Module Aims

Give the student an insight into stresses at surfaces, electrochemical activity so that suitable surface treatments that can be used to enhance performance of components and extend equipment life.

Syllabus

In this module, the emphasis will be on the performance of surface engineered materials and matching these to service conditions. Topics to be covered will include: • Tribologically induced stress, Hertz, dynamic Hertz, residual stresses, etc. • Stress field and wear interactions. • Measurement of surface / coating properties. • Wear mechanisms, including lubricated wear, wear-corrosion and erosion. Surface engineering processes. (1) Erosion resistant coatings deposited by Chemical Vapour Deposition, Physical Vapour Deposition, High Velocity Oxy-Fuel (thermal spray), and weld overlay. (2) Plating and nano-composite coatings/surfaces. (3) Corrosion resistant surfaces/high temperature. (4) Surface modification: induction hardening, ion- implantation, carburising, carbo-nitriding, nitriding and nitro-carburising. The lectures will draw on examples from applications within the marine, oil and gas, power generation, aerospace and biomedical sectors. Emphasis will be placed on gaining sustainability through correct surface engineering technology. Engineering assessment of each failure problem is described and the associated micromechanical failure modes. The economics of surface selection will be discussed for various examples, e.g. machine tool coatings, thermal barrier coatings and hard chromium replacement for aerospace.

Learning and Teaching

Teaching and learning methods

The teaching methods to be employed in the delivery of this module include: • 36 lectures (three 45 minute sessions per week) which develop the themes described in this module. Skeleton notes are given out at the start of the course, which means you only have to note down the key points during the lecture, but still have a full set of notes to work from. These will also be made available on Blackboard. • Additional research review papers are provided to give an overview of the themes of the course. • Formative online quizzes on Blackboard. • Solutions to assigned problems • Demonstrations and video materials where and when appropriate. The learning activities include: • Individual reading of background materials and course texts, plus work on examples. • Example sheets and solutions.
