Electrolyte Jet Machining (EJM) of antibacterial surfaces

Electrochemical jet manufacturing technology: From fundamentals to application

“…Nevertheless, EJM could offer opportunities where a selective approach might be useful, for example in the targeted removal of identified defects as part of a repair or reworking strategy. when compared with a rolled stainless steel surface [204]. This effect is likely to hold where the surface topography feature sizes approach the length scale of the microbe [205].…”

Tooling aspects of micro electrochemical machining (ECM) technology: Design, functionality, and fabrication routes

“…https://doi.org/10.1016/j.jmatprotec.2023.118098 (Hackert-Oschätzchen et al, 2012), selective micro-deposition (Li et al, 2022), as a cost-effective EBSD analysis tool (Speidel et al, 2021) and as an on-machine metrology tool. Besides this, the jets have been applied for controlled surface structuring (Lutey et al, 2021), three-dimensional machining (Natsu et al, 2008), plasma electrolyte polishing (Quitzke et al, 2022), selective anodizing (Kuhn et al, 2017) and selective cathodic hydrogenation (Zhao et al, 2020) as well.…”

Gas Bubble Evolution during ECM Process can be suppressed by Pulse Parameters: High Speed Videographic Observations during Early Stages of Bubble Evolution

“…Electrochemical machining (ECM) [1] removes material by controlled anodic dissolution of workpiece and its research and development has been backed by many industries particularly aerospace, consumer goods, automotive, and applications demanding high surface integrity and preservation of original microstructure. Recently demonstrated novel applications of ECM include large area surface texturing for antibacterial surfaces [2], smooth machining and reduced pitting of titanium alloys [3], surface structuring through electrolyte confinement [4], removal of EDM recast layer [5], processing of high entropy alloys [6] and niobium carbide [7], and fabrication of unclonable watermarks [8], just to name a few. The evolution of gas bubbles [9] in ECM process is a well-known phenomenon.…”
