Journal Article
Daure, J., Voisey, K., Shipway, P., & Stewart, D. (2017). The effect of coating architecture and defects on the corrosion behaviour of a PVD multilayer Inconel 625/Cr coating. Surface and Coatings Technology, 324, https://doi.org/10.1016/j.surfcoat.2017.06.009

This paper investigates the effect of substrate surface finish and deposition conditions of PVD multilayer Inconel 625/Cr coatings on their ability to act as a corrosion-barrier. The corrosion-barrier performance of the coatings was characterized by...

Application of high speed filming techniques to the study of rearwards melt ejection in laser drilling (2017)
Journal Article
Jones, C., Hann, D. B., Voisey, K., & Aitken, S. (in press). Application of high speed filming techniques to the study of rearwards melt ejection in laser drilling. Journal of Laser Applications, 29(2), Article 022204. https://doi.org/10.2351/1.4983269

Melt ejection is the dominant material removal mechanism in long, ms, pulse laser drilling of metals, a process with applications such as the drilling of cooling holes in turbine blades. Droplets of molten material are ejected through the entrance ho... Read More about Application of high speed filming techniques to the study of rearwards melt ejection in laser drilling.

Application of ray-tracing to interpreting beam prints from fibre laser cutting (2017)
Journal Article
Alotaibi, M., Atiyah, H., MacKenzie, R., & Voisey, K. (2017). Application of ray-tracing to interpreting beam prints from fibre laser cutting. Lasers in Engineering, 39(1-2),

2D ray-tracing has been used to investigate the influence of inclined cutting front and the cutting edge on the exiting, surplus, laser beam while cutting 6 mm mild steel with a fibre laser, wavelength = 1070 nm. The ray-tracing model, which assumed... Read More about Application of ray-tracing to interpreting beam prints from fibre laser cutting.

Role of oxides and porosity on high temperature oxidation of liquid fuelled HVOF thermal sprayed Ni50Cr coatings (2017)
Journal Article
Song, B., Bai, M., Voisey, K. T., & Hussain, T. (2017). Role of oxides and porosity on high temperature oxidation of liquid fuelled HVOF thermal sprayed Ni50Cr coatings. Journal of Thermal Spray Technology, 26(3), 554-568. https://doi.org/10.1007/s11666-017-0531-z

High chromium content in Ni50Cr thermally sprayed coatings can generate a dense and protective scale at the surface of coating. Thus, the Ni50Cr coating is widely used in high temperature oxidation and corrosion applications. A commercially available...

Evolution of damage in MoS2-based dry film lubricants (DFLs) in fretting wear – the effect of DFL thickness and contact geometry (2017)
Journal Article
Barman, K., Shipway, P., Voisey, K., & Pattinson, G. (2017). Evolution of damage in MoS2-based dry film lubricants (DFLs) in fretting wear – the effect of DFL thickness and contact geometry. Progress in Organic Coatings, 105, https://doi.org/10.1016/j.porgcoat.2016.12.022

Dry film lubricant (DFL) coatings are widely used to reduce coefficients of friction and damage in highly loaded contacts. This work investigates the behaviour of a commercially available MoS2-based DFL in a cylinder-on-flat contact geometry with a f...
