Shahid Beheshti University






Ahmad Reza Rastkar is Professor of Surface Engineering and Leader of Plasma Processing Lab at the Laser and Plasma Research Institute in Shahid Beheshti University. He is a leading surface engineering expert in developing novel surface engineering techniques to improve the wear and corrosion resistance of Steels, Titanium alloys and Nickel alloys technologies as well as characterization of surface engineered components.

Professor Rastkar has published more than 60 papers in international journals and conferences together with 4 patents and 2 book chapters. During the past 20 years, he has successfully achieved several innovations in surface transformations and binding difficult to bond alloys such as titanium aluminides and superalloys. Another achievement is the development of the growth of vertically carbon nanotubes on different substrates that would be applicable in new challenging industries such as batteries and high emission cathodes in different high voltage and optical industries.

He is active in international surface engineering activities including invited lectures to major international conferences, organizations of national and international conferences and is an outstanding reviewer of academic journals.
