Direct Writing Unclonable Watermarks with an Electrochemical Jet (2022)
Journal Article

Counterfeit parts result in significant losses per annum and are often dangerous, therefore they represent a serious concern for manufacturers and end users alike. Easily written but unclonable watermarks undermine the proposition of the counterfeite... Read More about Direct Writing Unclonable Watermarks with an Electrochemical Jet.

Failure modes in dual layer thickness Laser Powder Bed Fusion components using a novel post-mortem reconstruction technique (2022)
Journal Article

To exploit the design freedoms of Powder Bed Fusion, parameters can be varied within sub-volumes of components to achieve the optimal part for both service conditions and manufacturing productivity. This involves prioritising mechanical strength in a... Read More about Failure modes in dual layer thickness Laser Powder Bed Fusion components using a novel post-mortem reconstruction technique.

Electrolytic-dielectrics: A route to zero recast electrical discharge machining (2022)
Journal Article

Electrical discharge machining (EDM) is a widely used manufacturing process for machining hard or high melting point metals. A characteristic feature of this process is a brittle, porous and rough recast layer on machined surfaces, which undermines i...

Hydrophobically/oleophilically guarded powder metallurgical structures and liquid impregnation for ice mitigation (2022)
Journal Article

Icing hazards often pose operational and safety challenges. Various surface and coating approaches have been attempted for ice mitigation purposes, but the durability remains an outstanding issue. Inspired by traditional powder metallurgy and slipper... Read More about Hydrophobically/oleophilically guarded powder metallurgical structures and liquid impregnation for ice mitigation.

Stochastic design for additive manufacture of true biomimetic populations (2022)
Journal Article

Current biomimetic designs do not incorporate naturally occurring variance. Instead, the same unit cell is repeatedly copied and pasted to create a pattern. Existing stochastic designs use the same randomness for all parameters. However, nature teach... Read More about Stochastic design for additive manufacture of true biomimetic populations.

On the thermomechanical aging of LPBF alloy 718 (2022)
Journal Article

Heat treatment of products post additive manufacture are considered hugely important since the metallurgical condition post process is suboptimal. In the case of nickel-based superalloys, grain size, precipitate distribution and precipitate size are... Read More about On the thermomechanical aging of LPBF alloy 718.

Metallurgical reactions and tribological properties of self-lubricating Al-WS2 composites: Laser powder bed fusion Vs. spark plasma sintering (2022)
Journal Article

Self-lubricating aluminium-based composites reinforced with solid lubricants promise to meet the demand for lightweight materials in green tribological applications. The design advantages granted by additive manufacturing (AM) processes coupled with...

Chemical recovery of spent copper powder in laser powder bed fusion (2022)
Journal Article

In laser powder bed fusion (LPBF), recovered unfused powder from the powder bed often degrades upon sequential processing through mechanisms like thermal oxidation and particle satelliting from ejected weld spatters and particle-laser interactions. G... Read More about Chemical recovery of spent copper powder in laser powder bed fusion.
