Microstructural characterisation of Tristelle 5183 (Fe-21%Cr-10%Ni-7.5%Nb-5%Si-2%C in wt%) alloy powder produced by gas atomisation (2018)
Journal Article

Nitrogen gas atomised powders of the hardfacing alloy Tristelle 5183 (Fe-21%Cr-10%Ni-7%Nb-5%Si-2%C in wt%) were sieved into different particle size ranges and their microstructures have been investigated. Powder particles larger than approximately 53... Read More about Microstructural characterisation of Tristelle 5183 (Fe-21%Cr-10%Ni-7.5%Nb-5%Si-2%C in wt%) alloy powder produced by gas atomisation.

The effect of temperature on sliding wear of self-mated HIPed Stellite 6 in a simulated PWR water environment (2018)
Journal Article

Cobalt-based Stellite alloys are widely used in the primary circuit of pressurized water reactors (PWR) to protect valve surfaces against wear and galling in a corrosive environment. In this study, self-mated sliding wear of HIP-consolidated (Hot Iso... Read More about The effect of temperature on sliding wear of self-mated HIPed Stellite 6 in a simulated PWR water environment.

A comparison of the galling wear behaviour of PVD Cr and electroplated hard Cr thin films (2018)
Journal Article

Electroplated hard chromium (EPHC) is used in many industries as a wear and corrosion resistant coating. However, the long term viability of the electroplating process is at risk due to legislation regarding the toxic chemicals used. The physical vap...

Corrosion of cast Stellite-3 analogue in simulated PWR conditions (2018)
Journal Article

© 2018 Elsevier Ltd Wear resistant alloys are required for deployment in pressurised water reactor primary circuits and in this context, the corrosion behaviour of a cast cobalt-based alloy following exposure for 30 days in lithiated water at 300 °C...

Process parameter optimisation of laser clad iron based alloy: Predictive models of deposition efficiency, porosity and dilution (2018)
Journal Article

As a candidate coating material for heat-exchanger surfaces in commercial power generation boiler, an amorphous/glass forming Fe-Cr-B alloy NanoSteel SHS 7170 was deposited by a 2 kW fibre laser onto a boiler grade steel substrate (15Mo3). A comprehe... Read More about Process parameter optimisation of laser clad iron based alloy: Predictive models of deposition efficiency, porosity and dilution.

The role of a thermally sprayed CuNiIn underlayer in the durability of a dry-film lubricant system in fretting: a phenomenological model (2018)
Journal Article

Dry film lubricant coatings (DFL) are employed to reduce friction and damage in highly loaded contacts. Metallic underlayers, e.g. CuNiIn, can be beneficial however, there is no detailed explanation of the mechanism. This work investigates the effect...

Effects of surface roughness on local friction and temperature distributions in a steel-on-steel fretting contact (2018)
Journal Article

It has generally been assumed that initial surface roughness has significant influences on local frictional shear stresses and flash temperatures in fretting contacts. However, since these hypotheses are difficult to directly measure, the frictional...
