About
Arutiun obtained his PhD in Plasma Science and Surface Engineering after undergraduate studies at the University of Sofia 'St Kliment Ohridski', Bulgaria, and obtaining the degree of BSc (Hons) in Applied Physics from the University of Salford, UK.
His research concentrates on development of plasma PVD technologies to improve the properties and performance of coatings used for wear, oxidation and corrosion protection in automotive and aerospace industries, as well as through-silicon via metallisation for semiconductor wafer processing, thin film photovoltaics, and cryogenic materials. He has developed technologies for substrate pretreatment prior to coating deposition to improve adhesion, deposition of coatings with dense microstructure, low-pressure plasma nitriding and hybrid processes of plasma nitriding/coating deposition. He has experience with cathodic vacuum arc discharges, dc and pulsed magnetron discharges, and radio-frequency coil enhanced magnetron sputtering. He utilises plasma diagnostics such as optical emission spectroscopy (OES), electrostatic probes, energy-resolved mass spectroscopy and atomic absorption spectroscopy. Materials characterisation includes high-resolution TEM, STEM, STEM-EDS, SEM, and XRD as well as mechanical testing available at NTCPVD.
Arutiun is one of the pioneers of high power impulse magnetron sputtering (HIPIMS) technology and his work on plasma diagnostics, coating deposition and pretreatment with HIPIMS has received seven awards, including:
