The module will cover extreme environments for all materials classes such as extreme local atmospheres; localised stresses; extreme temperatures. Examples studied include friction and wear, irradiation (both UV and ionising) and gas-solid, liquid-solid, solid-solid reactions at extreme temperatures. Surfaces at the atom / molecule level and origins of frictionMechanisms of adhesive or abrasive wear and strategies for avoidance of both types of wear. Surface engineering, wear resistant coatings, implantation and coating technologies. Ion - material interactions related to radiation damage in nuclear and space applications. Moderators and strategies for mitigating ion damage. Gas-solid reactions: kinetics and thermodynamics. Strategies to mitigate corrosion damage. Very high temperature structural materials. These link to the 2017 QAA Materials subject benchmark statements:
Properties
iv mechanical behaviour - elastic and plastic deformation, creep and fatigue, fracture, strengthening, toughening and stiffening mechanisms
Application
xi materials design - compositional variation and processing to achieve required microstructures, and hence properties xii materials selection - consideration of all material types, materials processing methods, and product costs xiii degradation/durability of materials - effect of environment upon performance, corrosion, wear, and biodegradation
Learning Outcomes
At the end of this module students should be able to:
Explain the atomic nature of surfaces and the mechanisms of friction and wear in materials;
Describe and explain surface engineering techniques and coatings to mitigate wear and corrosion;
Explain ion-solid and gas-solid interactions using thermodynamics concepts
These link to the AHEP v4 learning outcomes

Apply knowledge of mathematics, statistics, natural science and engineering principles to the solution of complex problems. Some of the knowledge will be at the forefront of the particular subject of study (C1)
Analyse complex problems to reach substantiated conclusions using first principles of mathematics, statistics, natural science and engineering principles (C2)
Select and evaluate technical literature and other sources of information to address complex problems (C4)
Use a risk management process to identify, evaluate and mitigate risks (the effects of uncertainty) associated with a particular project or activity (C9/M9)
Use practical laboratory and workshop skills to investigate complex problems (C12/M12)
Select and apply appropriate materials, equipment, engineering technologies and processes, recognising their limitations (C13/M13)
Apply a comprehensive knowledge of mathematics, statistics, natural science and engineering principles to the solution of complex problems. Much of the knowledge will be at the forefront of the particular subject of study and informed by a critical awareness of new developments and the wider context of engineering (M1)
