Microstructure formation in the powder HIPed hardfacing alloy Tristelle 5183 (Fe-21%Cr-10%Ni-7.5%Nb-5%Si-2%C in wt%) (2021)
Journal Article

Tristelle 5183 (Fe-21%Cr-10%Ni-7%Nb-5%Si-2%C in wt%) is an alternative material to cobalt-based alloys for wear resistant hardfacing applications. In this work, gas atomised powder was consolidated by hot isostatic pressing (HIPing) at 1120 ± 10 oC w...

Understanding and modelling wear rates and mechanisms in fretting via the concept of rate-determining processes - Contact oxygenation, debris formation and debris ejection (2021)
Journal Article

A new framework which describes the role of three key processes in fretting wear of metals is proposed, with these three processes being: (i) oxygen transport into the contact; (ii) formation of oxide-based wear debris in the contact and (iii) ejecti...

Interaction of displacement amplitude and frequency effects in fretting wear of a high strength steel: Impact on debris bed formation and subsurface damage (2021)
Journal Article

In previous work, fretting frequency has been observed to have a significant impact not only on wear rates, but also on the nature of fretting debris and the development of subsurface damage; however, while the “frequency effect” has been shown in so...

Time-dependence and exposure-dependence of material removal rates in fretting (2021)
Journal Article

Fretting generally results in either material removal or fatigue, or a combination of both. Although the term is rarely used now, in the early literature addressing this subject, fretting that resulted in material removal was sometimes termed “fretti...

Contact size and debris ejection in fretting: The inappropriate use of Archard-type analysis of wear data and the development of alternative wear equations for commonly employed non-conforming specimen pair geometries (2021)
Journal Article

It has been long understood that fretting differs from sliding wear in that the relative displacement between the bodies is generally smaller than the size of the contact between them, with debris ejection from the contact thus playing an important r...

Measurement of friction in galling testing – An example of its use in characterising the galling behaviour of hardfacings at ambient and elevated temperature (2021)
Journal Article

© 2021 Elsevier B.V. Galling is a category of severe adhesive wear that is defined by surface damage arising between sliding solids, distinguished by macroscopic, usually localized, roughening and creation of protrusions above the original surface. T... Read More about Measurement of friction in galling testing – An example of its use in characterising the galling behaviour of hardfacings at ambient and elevated temperature.

Microstructural characterisation of subsurface deformation and the degradation of Stellite 6 induced by self-mated sliding contact in a simulated PWR environment (2021)
Journal Article

© 2021 Elsevier Ltd Stellite 6 (Co-29.5%Cr-5%W-1.2%C in wt%) is traditionally used as a hardfacing material in the primary circuit of pressurised water reactors (PWRs) due to its good corrosion and wear resistance in water at up to 300 °C. In this st... Read More about Microstructural characterisation of subsurface deformation and the degradation of Stellite 6 induced by self-mated sliding contact in a simulated PWR environment.
