Dr Sue Impey is a
materials scientist with over 30 years expertise in surface characterisation
and thin oxide coatings for a range of applications. Examples include surface protection to
enhance corrosion resistance and novel applications in
Impey has conducted research in surface engineering into oxidation and
corrosion aspects building and industrial pipeline services, casting and
manufacturing industry, high temperature coatings for aerospace, and ceramics
thin film sensors for microelectronics, automotive and aerospace manufacturing sectors.
Dr Impey is the academic lead responsible for the management of analytical equipment for surface and materials characterisation at Cranfield University and all resources. She provides support to the University and a service to industry in materials characterisation and failure analysis using analytical methods. She instigated and delivered (March 2021) a significant investment in scanning electron microscopy for the University for the benefit of external clients, students and staff.
Appointed to the lecturing staff in 2003, and Senior Lecturer in 2009, she
undertakes teaching and academic activities. Dr Impey has developed and
directed Manufacturing Technology and Materials MSc courses since 2003 for the University supporting MSc programmes in
Aerospace Materials, Advanced Materials, Applied Nanotechnology, Microsystems
and Nanotechnology), Welding Engineering, Manufacturing Technology and
Management and the recent level 7 Apprenticeship (Mastership) in materials
process engineering. She currently directs the Aerospace Materials MSc.
Sue joined Cranfield from the chemical industry in 1995. She has a PhD in Metallurgical Engineering for work in aluminium alloy oxidation and recycling and MSc in Aerospace Materials.
Dr Impey seeks excellent PhD candidates who are eager to learn and carry out research in nanomaterials, surface engineering, thin films, coating manufacturing development and component lifetimes.
