This paper provides quantitative information about the paths taken by blown powder particles during laser cladding. A proportion of the powder is "wasted" by bouncing off the solid areas surrounding the melt pool. This wastage reduces the productivit...

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...

An investigation into standard laser cladding and the ABA cladding technique. Journal of Laser Applications, 35, Article 012025. https://doi.org/10.2351/7.0000904

This paper investigates the efficiency of powder catchment in blown powder laser cladding (a directed energy deposition technique). A comparison is made between standard “track by overlapping track” cladding (“AAA” cladding) and “ABA” cladding, where...
