Journal Article
Carrington, M., Daure, J., Utada, S., Ratia-Hanby, V., Shipway, P., Stewart, D., & McCartney, D. (2024). The evolution of subsurface deformation and tribological degradation of a multiphase Fe-based hardfacing induced by sliding contact. Materials Science and Engineering: A, 892, Article 146023. https://doi.org/10.1016/j.msea.2023.146023

Multiphase Fe-based hardfacing alloys, for example Tristelle 5183 Fe-21%Cr-10%Ni-7.5%Nb-5%Si-2%C in wt.%, are extensively used for tribological applications, including valves, bearings and drive mechanisms, where two surfaces are unavoidably subjecte...

Experimental and numerical investigations of sliding wear behaviour of an Fe-based alloy for PWR wear resistance applications (2023)
Journal Article
Bastola, A., McCarron, R., Shipway, P., Stewart, D., & Dini, D. (2024). Experimental and numerical investigations of sliding wear behaviour of an Fe-based alloy for PWR wear resistance applications. Wear, 540–541, Article 205186. https://doi.org/10.1016/j.wear.2023.205186

The excellent wear and corrosion resistance of Co-based alloys make them desirable for tribological applications in the nuclear industry. However, neutron activation of the Co-based alloys leads to significant occupational radiation doses. An alterna...

Lifetime of MoS2 based DFL systems in fretting with and without a Cu-Ni-In under-layer: the dependence on the topography of the surface onto which the DFL is deposited (2023)
Journal Article
Laolu-Balogun, E., Owen, S., Booth, T., Pattinson, G., Shipway, P., & Voisey, K. (2023). Lifetime of MoS2 based DFL systems in fretting with and without a Cu-Ni-In under-layer: the dependence on the topography of the surface onto which the DFL is deposited. Tribology International, 188, Article 108863. https://doi.org/10.1016/j.triboint.2023.108863

The superior fretting performance of polymer-bonded MoS2-based dry film lubricant (DFL) coating on a plasma-sprayed Cu-Ni-In under-layer is well known. The Cu-Ni-In under-layer changes both the material and the topography of the sur...

Galling of stainless steels as a function of test conditions in an ASTM G196-type test setup – The role of temperature, rotational velocity, interrupted rotation and rotational distance (2023)
Journal Article
Daure, J. L., Kóti, D., Carrington, M. J., McCartney, D. G., Stewart, D. A., & Shipway, P. H. (2023). Galling of stainless steels as a function of test conditions in an ASTM G196-type test setup – The role of temperature, rotational velocity, interrupted rotation and rotational distance. Wear, 524-525, Article 204804. https://doi.org/10.1016/j.wear.2023.204804

Austenitic stainless steels have attractive properties for use in corrosive environments, but their use in components where motion under load is experienced (such as valves) is limited by their poor galling behaviour. Whilst stainless steels with imp...

Debris expulsion as a rate determining process in fretting – The effect of slip amplitude on debris expulsion behaviour and rates (2023)
Journal Article
Zhu, T., Bennett, C. J., & Shipway, P. H. (2023). Debris expulsion as a rate determining process in fretting – The effect of slip amplitude on debris expulsion behaviour and rates. Wear, 523, Article 204818. https://doi.org/10.1016/j.wear.2023.204818

In contrast to the well-established understanding of sliding wear, recent work has clearly demonstrated that the instantaneous wear rate in fretting of metals is dependent upon the contact size due to the fact that transport of species in and out of...
