Prof. Vijay’ research interests are in the development of techniques for quantification of corrosion rate. Using principles of electrochemical hydrogen sensing combined with classical impedance spectroscopy a novel technique to screen polymer coatings for corrosion protection was developed [1]. As part of IITBMonash Academy, with Prof. MJNV Prasad and Prof. Raman Singh (Monash), current work focusses on understanding the effects of microstructure and stress on corrosion of biodegradable magnesium alloys for temporary human implant applications [2]. As part of the Startup Research Grant (SRG) funding provided by Science and Engineering Research Board (SERB), India development of a novel insitu electrochemical hydrogen permeation setup to work in tandem with tensile stress application to identify hydrogen and stress effects on failure of dual phase steels with defined microstructure relevant for the automobile industry is ongoing [3].
