Electrochemical jet machining of Ti-alloys in a deep eutectic solvent electrolyte

This study investigates the surface and electrochemical jet machining (EJM) characteristics of Ti CP1 and Ti-6Al-4V in a deep eutectic solvent-based electrolyte, with a focus on grain size effects, machining mechanisms, and material behaviour under tensile load. Surface roughness data, supported by images and surface reconstructions, highlights the impact of grain size on the surface finish of both materials. Data reveals no significant difference in material removal volumes between Ti CP1 and Ti-6Al-4V, although differences in profile width and are observed. These variations are attributed to the distinct machining mechanisms influenced by the oxide layer thickness in each material. The study also examines the application of EJM for material characterization under tensile load, with images of localized regions showing varying strain levels.
