My research focuses on surfaces, interfaces and coatings technologies. I am particularly interested in the understanding of novel materials processing techniques, especially thermal spray and cold gas dynamic spray. Process-microstructure-properties relationship is at the heart of my research. My latest research focus is in suspension and solution precursor thermal spraying to manufacture functional coatings from sub-micron to nanometer range feedstock particles. We are currently working with axial and radial injection high velocity oxy-fuel (HVOF) thermal spray, axial injection suspension plasma spray, high pressure cold spray and low pressure cold spray technologies.
We have recently developed comprehensive environmental test facilities to evaluate the performance of various coatings in type I and II hot corrosion, superheated steam oxidation, erosion-corrosion test, thermal cycling and high velocity steam impact. Our bespoke test facilities also include room temperature to 1000 C sliding wear test rigs. I am part of the Advanced Materials Research Group.
I received a PhD in Materials Manufacturing from the University of Nottingham, which was followed by an MSc in Manufacturing Engineering. In my doctoral research, I investigated the high strain-rate deformation of titanium alloys using a novel cold gas dynamic spraying (a near net shape/additive manufacturing) technique. The process is still at its early stages and has the potential to be established as a high deposition rate additive manufacturing technique. My contribution to the scientific community was to propose a novel bonding mechanisms in the solid-state particle deformation. I am also a graduate in Mechanical Engineering.
Following my doctoral research, I worked as a research fellow (academic) at the Cranfield University, where my research was focused on high temperature performance of advanced materials and coatings for low carbon power generation technologies. I was involved in developing high velocity oxy-fuel coatings, plasma spraying coatings, laser deposited coatings, as well as diffusion slurry coatings for ultra supercritical power plants and biomass fired boilers. I designed a programme of research for two large TSB funded projects and implemented the research plan on a large EU FP7 funded project . I was the course director for MSc in Offshore and Ocean Technology with Materials Engineering.
PhD studentships and Postdoctoral Fellowships
I welcome enquiries from prospective PhD students and postdocs. Studentships and postdocs tend to be funded through specific grants in the UK, so these will be advertised at https://www.jobs.ac.uk whenever they get approved for funding.
Students with an excellent academic record (1st class undergraduate degree or a distinction in a relevant Masters level course) might be eligible for an Faculty fo Engineering PhD studentship. Contact me if you would like to develop a project together.
I also welcome enquiries from overseas students and postdocs who have identified potential funding routes.
Current postdocs interested in applying for independent research fellowships (see https://www.nottingham.ac.uk/research/researchwithus/fellowships/fellowships.aspx) are encouraged to contact me if you are interested in conducting materials research at Nottingham. Our research group had several successful fellowship applications in recent years, and I would be happy to work with you in developing a competitive internal or external fellowship application. These fellowships typically require an outstanding publication track-record.

Suspension and Solution precursor thermal spraying: We have commissioned the UK's first direct injection suspension and solution precursor HVOF thermal spray in 2015. We are studying the process- microstructure- properties relationship of various ceramic materials, which are prepared from sub-micrometre to nanometre sized powder feedstock dispersed in water and alcohol. The research is focused on functional materials for energy applications to provide step changing technological solutions.
High Velocity Oxy-Fuel spraying: Work continues on the development of coatings using High Velocity Oxy Fuel (HVOF) spraying for power generation industry to combat aggressive fireside corrosion in the pulversied fuel and the fluidised bed boilers. We are developing novel multi-layered coatings for ultra supercritical power plants, which operate at higher temperatures (and pressures) thus increasing efficiency and reducing CO2 footprint. Process-property-performance of HVOF sprayed coatings in fossil fuel fired and co-fired (biomass/ waste) boilers are of great interest to us.
Cold Gas Dynamic Spraying: The work concerns the process development of cold gas dynamic spraying (CGDS) as a surface engineering tool, as well as a near net shape manufacturing technique. The work is supported by high speed laser particle image velocimetry (PIV), mercury intrusion porosimetry, pycnometry, ASTM pull-off adhesion tests and a state-of-the art material characterisation laboratory. Current research focuses on cold spraying of copper, aluminium, titanium and nickel based alloys. I am interested in understanding the bonding mechanisms in the high strain rate deformation process in cold-spraying. We are currently developing a micro cold spraying system for direct writing and additive manufacturing.
Laser cladding: As part of the significant research interest in the laser manufacturing processes at the school of engineering, my interests lie in the microstructure- performance relationship of the laser claddings for the heat exchangers (superheaters/ reheaters) in power plants. Current projects are developing high temperature corrosion resistant laser claddings for biomass fired boilers. I also have a keen interested in laser surface treatment of thermal sprayed coatings.
