What’s next for spray-based coatings? Materials for nanocomposites and functional coatings
Suspension and solution precursor thermal spray coating technologies are now at a crossroads—innovations from universities can potentially make a significant impact in many high value engineering applications through appropriate materials design and engineering approach. This talk will cover key research highlights, underpinned by latest scientific understanding, on suspension and solution precursor thermal spray from the University of Nottingham over the last five years with a particular emphasis on combustion based technologies for nanocomposite and functional coatings. The talk will explore our journey in suspension HVOF thermal spray of a range of feedstock materials: alumina for ultra-low wear in hot section of the aeroengines, titania for photo catalytic applications, yttria-stabilised zirconia for thermal barrier coatings and ceria for hydrophobic surfaces. Key materials requirements for applications will be explored with a particular aim to produce nanocomposite coatings with graphene nano-platelets. Graphene is an exciting new material for the 21st century and its success will rely on cheap, large scale incorporation of graphene into ceramic or metallic matrix that can have a step-change improvement in performance. Solution precursor thermal spray is another emerging technology that enables us to design microstructure which was not possible through conventional particulate based thermal spray, this talk will explore aspects of solution precursor thermal spray and how far that philosophy can influence materials processing. Finally, it will cover latest highlights from our on-going work at the UK neutron diffraction facility on suspension and solution precursor sprayed coatings along with numerical modelling to understand these emerging processes.
Dr Tanvir Hussain is as Associate Professor in Materials Engineering (Coatings) at the Faculty of Engineering, University of Nottingham (UK), which is a research-led Russell Group university and it is internationally recognised for the research in advanced materials. Faculty of Engineering was ranked 3rd in terms of Research Power in the latest round of the national Research Assessment Exercise (REF).
Dr Hussain leads the Coating Materials for Energy team with 13 PhD students, 2 Postdoctoral Research Fellows and 3 visiting researchers under his direct supervision. He serves as an Associate Editor of the Journal of Thermal Spray Technology, Associate Editor of the Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology and a member of the BSI standards committee on STI/040 Thermal spraying and thermally sprayed coatings. He is a full member of the EPSRC (Engineering and Physical Sciences Research Council) peer review college. He has published 50+ peer reviewed journal papers, 35 peer reviewed conference papers and 2 book chapters on high velocity oxy-fuel thermal spray, cold spray and suspension spray. He has recently established the UK’s research base in suspension and solution precursor spray to produce nanostructured and nanocomposite coatings. He also holds a patent on a process to incorporate graphene into ceramic coatings through suspension thermal spray.
His current research portfolio of £1.4 m is funded by the UK research council, Innovate UK and industry. He has attracted major funding from industry including Rolls-Royce university technology centre (UTC) in Gas Turbine Transmission, UTC in Manufacturing, EON Technologies, Bombardier Transportation, Wallwork Heat Treatment, Monitor Coatings, and The Welding Institute.
