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.

Effects of surface roughness on local friction and temperature distributions in a steel-on-steel fretting contact (2018)
Journal Article
Qin, W., Jin, X., Kirk, A., Shipway, P., & Sun, W. (2018). Effects of surface roughness on local friction and temperature distributions in a steel-on-steel fretting contact. Tribology International, 120, https://doi.org/10.1016/j.triboint.2018.01.016

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...

A finite-element-based wear modelling methodology and a computational device for decoupling wear effects is presented in this study. The decoupling of wear effects facilitates the capture of plasticity accumulation on a particular wear-scarring profi...

The role of geometry changes and debris formation associated with wear on the temperature field in fretting contacts (2016)
Journal Article

The temperature of a fretting contact is known to be a key factor in its development. However, as a test proceeds, the wear scar changes, both geometrically and through the formation of oxide-based debris-beds. Accordingly, the effects of these on th...

A high carbon (C70S6) steel has been laser surface treated using CO2 and Diode lasers in order to produce an embrittled region to act as a fracture notch. Such a process has been investigated as a precursor to the fracture splitting of automotive eng...
