RELIABLE: Wear Resistant Lightweight Aluminium Brakes for Vehicles is now available from Suman Shrestha, Keronite, on the EuroBrake website. He answers a few related questions in this Spotlight.
What do you find most interesting about the topic you are presenting on?
Heavy cast-iron discs are part of "unsprung-mass" and affects fuel efficiency and impacts on greenhouse gas (GHG) exhaust emission. In addition, non-exhaust emission, such as Brake wear particles (PM) from the cast iron discs in urban air pollution has been linked to a range of acute health conditions, (e.g. respiratory and cardiovascular, asthma, Alzheimer's disease). Light metals such as aluminium alloy combined with a hardwearing ceramic coating by environmentally friendly and advanced plasma electrolytic oxidation (PEO) technology can potentially replace heavy cast iron brake discs with subsequent benefits of reductions in GHG and PM.
How has coronavirus affected your work and has it had a direct impact on the work you are presenting?
Covid-19 has affected almost everyone in the world and we are not an exception. Covid 19, resulted in delaying of the research and development work I am presenting due to plant closures and other challenges, including slowdown in OEM’s own development planning and budget. In addition, due to the pandemic, we could are going for virtual presentation. The actual conference and meeting people could have brought a very different dynamics in B2B relations.
Who do you think will be most interested in seeing your presentation and who would you most like to ask questions about it?
Vehicle manufacturers (both standard and electrical vehicles), industries (e.g. brake disc and brake pad manufacturers), RTO, Universities, government organisations interested and working today to help improve fuel efficiency and reduce exhaust and non-exhaust emissions.
After an MSc in Mechanical Design Engineering from St. Petersburg and a PhD in Materials Engineering from Glasgow, Suman spent five years at TWI Ltd helping aerospace and oil & gas industries working on a wide variety of surface technologies, including, then a relatively new, Keronite plasma electrolytic oxidation (PEO) technology during its early establishment in 2000. He subsequently joined Keronite Plc in 2005 to focus on research, application development and commercial exploitation of the PEO technology on light alloys for aerospace, automotive and semi-conductor industries including Airbus, Boeing, ESA, Innovate UK.
With over 200 confidential industry reports, Suman has also published over 65 journal & conference papers, book chapter including two patents and one pending. He has worked in the capacity of Symposium Organiser, Chair and Scientific Committee member for Intl. Conferences such as SMT21-Paris, SMT22-Trollhattan, Euromat 2009-Glasgow, Euromat 2011-Montpellier, SMT29-Copenhagen, SMT30-Milan, SMT31-Mons, Eurobrake 2017-Dresden, SMT32-San-Sebastian and SMT33-Naples.
He was offered a USSR scholarship to pursue his engineering degree in St. Petersburg and later received Glasgow University Postgraduate and Overseas Research Scholarship (ORS) awards to pursue his PhD. He is a recipient of Lenin Gramota and Red Diploma (highest achievements in education) from Russia followed by Nepal’s two highest educational decorations ‘order of the Mahendra Vidyabhushan Medals’ from His late Majesty King Birendra. He is a Visiting Professor and Industrial Advisory Board member for the University of Leeds and is on the Editorial Board for Journals of i) ‘Surface Engineering’, ii) ‘Tribology - Materials, Surfaces & Interfaces’ and iii) ‘American Journal of Aerospace Engineering’. He is a Chartered Engineer; Chartered Scientist; Fellow (IOM3) and Fellow (IMechE).
