Investigating of the processing boundaries of Micro Electrochemical Machining Process

The processing boundaries of the micro electrochemical process will be investigated. These include voltage gap, pulses duration and off-time duration, electrolyte flow (especially for micro features machining), electrolyte composition based on processing material. The idea is at the end to be created a benchmark research process that can be conducted for a specific application in order to determine the processing parameters. The project will create a methodology to be followed to determine for each specific case the gap needed, the voltage needed the electrolyte composition and concentration, pulse time ON and time OFF. A micro ECM machine is available for the project and 2 clean rooms and a potentiostat. The potential after the successful end of the project is huge as all previous PhD students have secured employment immediately after their graduation.

Atanas Ivanov - Dr Ivanov world-leading expertise in non-traditional manufacturing spans over a decade of innovating and developing new technologies. In 2007 he was registered by GUINNESS BOOK RECORD for drilling the smallest hole in the world ø22µm 10 aspect ratio. From 2008 Dr Ivanov was the only producer of samples for cryogenic sensors from InSb for the European space programme and NASA. In 2009 he designed of the control of the mirrors for HERCHEL and PLANCK satellites and the sampler (ISOSAMPLER) for NASA for their ‘Medusa’ project for Mars and Jupiter missions. Dr Ivanov registered a world patent for using cutting tools as measuring probes as part of his work fr the Basque government in 2010. After joining Brunel he developed the first in the world micro electrochemical drilling machine for the fuel injection systems for BMW (SONPLAS). In 2013 Dr Ivanov built the first µECM milling machine. In the last 10 years Dr Ivanov acquired 15 grants and an income of over £1m as PI only, and an additional income as a collaborator. In 2018 he received an Innovate UK grant for developing a technology for the identification of airplane fasteners. Dr Ivanov is a world-leading specialist in µECM machining technology. In 2019/20 he developed world-leading µECM technology for sharpening glaucoma needles.

Abhishek Lahiri - Dr. Lahiri joined Brunel University as lecturer in March 2020. He got his PhD from University of Leeds in 2008 after which he went on to do his Postdoc in USA and Japan. From 2011 he joined Clausthal University of Technology in Prof Frank Endres group and worked extensively on electrodeposition in ionic liquids and understanding the battery electrode/electrolyte interface. His work primarily focusses on electrochemical synthesis of functional materials using ionic liquids for energy storage and electrocatalysis. In ionic liquids, the electrode/electrolyte interface is considerably different from aqueous electrolytes and therefore controlling and modifying the interface leads to change in functional properties of the materials. His research focusses and utilises the property of interfacial modulation to develop new functional materials and tries to bridge the gap between fundamental aspects of electrochemistry and applied electrochemistry. Questions such as can we design a suitable interface to develop dendrite-free deposits which are essential for developing high energy density Li/Na metal batteries are targeted. Besides, developing batteries for grid energy storage with sustainable materials are being researched.
