Professor of Surface and Interface Science

Background:

Gary has worked for º¬Ðß²ÝÊÓƵ since January 1987; initially as a member of the Surface Analysis Group of º¬Ðß²ÝÊÓƵ Consultants Ltd located within the Physics Department. In 1990 this group became the Institute of Surface Science and Technology (ISST) and was later integrated within the Institute of Polymer Technology and Materials Engineering (IPTME) now the Department of Materials. Gary is currently Professor of Surface and Interface Science, responsible for a number of major fundamental research projects and at any moment in time manages a number of industrial consultancies. He became Head of the Department of Materials in 2017 until July 2020.

Qualifications:

  • BSc, York
  • PhD, º¬Ðß²ÝÊÓƵ
  • FIMMM, FIMF

Key awards:

  • Corrosion Award 2002 from the Royal Society of Chemistry (RSC)
  • J.M.Rape Memorial Medal from the Institute of Metal Finishing (2009)
  • Canning Bi-Centenary Medal 2010 from the Institute of Metal Finishing, for his paper “Hot and cold cleaning methods: CO2 and Nd:YAG laser ablation, sodium hydride immersion and CO2 cryoblasting”

Outline of main research interests:

Gary’s research interests include the invention and development of novel surface processes and multifunctional materials which are aimed towards meeting the specific demands of industry. This research is multidisciplinary in nature, drawing from expertise in the fields of; materials, mechanical engineering, physics and chemistry.

Current studies are concerned with: the development of novel processes for optimised adhesion and corrosion resistance imparted to metals including aluminium alloys and steels and the modelling of joints to determine the lifetime of bonded structures taking into account complex loading and environmental considerations. Some prebond treatments, particularly those suitable for aerospace use have been upscaled for commercial use. Gary also has a large interest in polymer modification using nanoparticles to provide adhesives and coatings with advanced properties.

Grants and contracts:

  • Optimisation of Stress Transfer in Adhesively-bonded Armour - Dstl (UK) and DGA (France) - value £236k
  • Materials and Processes for the Production of Low Cost Turbojet Components - Microturbo (France) - value £109k
  • Study of Conducting Oxides - European Space Agency - value £178k
  • Strategies for Dismantleable Adhesion - Dstl-AWE - value £144k
  • HITEA: REACH Compliant Chrome Replacements for Corrosion Protection - EPSRC-TSB - value £2.2M
  • AMSCA: Accelerated Manufacturing with Chrome Free Sacrificial Coatings in Aerospace - TSB - value £2.1M

Commercialisation of research:

Inventor of patent GB 2421 959 A Anodising of Aluminium Alloy.
Commercialisation ongoing in collaboration with Bombardier Aerospace.

In a consultancy capacity Gary has authored over 500 confidential reports to industrial clients from all manufacturing sectors on topics including:

  • Thin film characterisation
  • Various aspects of surface engineering
  • Corrosion
  • Failure analysis and contamination identification

These have consultancies have led to an income of over £1M to date for º¬Ðß²ÝÊÓƵ.
