Professor Papken Hovsepian

Head of Thin Films Research Centre

Summary

Professor Hovsepian is head of the Thin Films Research Centre and the Nanotechnology Centre for PVD Research at MERI. His major field of endeavour is fundamental research and development of technologies for deposition of application tailored nanoscale multilayer structured PVD coatings using advanced deposition techniques such as Magnetron Sputtering, Cathodic Arc Evaporation and HIPIMS. Examples include corrosion and wear resistant coatings, high temperature oxidation resistant coatings, tribological low friction coatings and coatings for biomedical applications. Professor Hovsepian has published more than 240 scientific papers, has been granted 12 patents. He is a member of EJCPISE, IUVSTA, BVC and a Fellow of the Institute of Physics, UK.

  • About

    Papken Hovsepian joined the Materials and Engineering Research Institute at Sheffield Hallam University in 1997 and took up a Personal Chair in 2004. He has more than 30 years of experience in PVD development and has carried out pioneering work on the development of Cathodic Arc PVD technology and systems leading to industrial implementation of the process.

    At present he is head of the Thin Films Research Centre and the Nanotechnology Centre for PVD Research at MERI. His major field of endeavor is fundamental research and development of industrial technologies for deposition of application tailored nanoscale multilayer/superlattice structured PVD coatings using various advanced deposition techniques such as Magnetron Sputtering, Cathodic Arc Evaporation and HIPIMS. Some examples include corrosion and wear resistant coatings, high temperature oxidation resistant coatings, tribological low friction coatings and coatings for biomedical applications. Other fields of interest are coatings for decorative applications (Nb based), and duplex technologies combining plasma nitriding with PVD coatings.

    Professor Hovsepian has published more than 240 scientific papers, has been granted 12 patents, 3 product patents and contributed chapters in two books dedicated to the PVD technology.

    Professor Hovsepian is involved in partnerships with large number of European, USA and Far East companies, as well as leading research organisations such as Fraunhofer.

    He is a co-inventor of the High Power Impulse Magnetron Sputtering (HIPIMS) technology for surface pre-treatment, a Sheffield Hallam University-patented technology licensed to a number of world leading PVD companies: IHI Ionbond, SVS, IHI Hauzer Techno Coatings, CemeCon and The Gillette Company.

    He was a member of European Joint Committee on Plasma and Ion Surface Engineering (2000-2016). He is Vice Chair of the Thin Film Division of the International Union for Vacuum Science, Technique and Applications, IUVSTA and member of the British Vacuum Council. He is a Fellow of the Institute of Physics, UK.
