Research Fellow


Summary

Yashodhan has a PhD in Mechanical Engineering from Strathclyde University, Glasgow. His research interests include Sputtering, HIPIMS, Surface Engineering, Tribology, Tribo-corrosion, and surface analysis. Since 2006 he has been involved in process development and optimisation for deposition of nanoscale multilayer coatings using Unbalanced Magnetron Sputtering and HIPIMS. His development work covers a wide range of applications; from decorative coatings to hard-wear resistant, corrosion, high temperature oxidation resistant as well as bio-medical coatings for artificial joints. He was awarded the R.F. Bunshah award by the ASED (AVS), USA for his work in erosion-corrosion studies involving PVD coatings in 2004.

About

Yashodhan Purandare has obtained a PhD in Mechanical Engineering from University of Strathclyde in Glasgow, UK. His PhD project involved aqueous erosion-corrosion studies of superlattice CrN/NbN PVD coatings. Prior to his PhD, he has a Bachelor degree and a Diploma in the field of Metallurgical Engineering from University of Pune, India.

He has also obtained valuable experience in heavy engineering industry involving welding and fabrication of pressure vessels and its quality control. He is a keen researcher and has been involved in research projects throughout his academic and industrial career. His pioneering work of mapping the effect of impact angle and velocity on the erosion-corrosion mechanisms for the superlattice CrN/NbN PVD coatings was awarded with the R.F. Bunshah Award -best paper presented in Session E –ICMCTF, San Diego, USA 2004 and with runners up prize in the Bodycote prize paper competition, Canada 2005.

Yashodhan joined the Nanotechnology Centre for PVD Research in October 2006 as a postdoctoral researcher. His research interests include Sputtering, HIPIMS, Tribology, Tribo-corrosion, surface engineering and surface analysis. Since 2006 he has been involved in development and optimisation of processes for deposition of application based nanoscale multilayer coatings using Unbalanced Magnetron Sputtering and HIPIMS. His development work on coating covers a wide range of applications; from decorative to hard-wear resistanr, corrosion resistant, high temperature oxidation resistant as well as bio-medical coatings for artificial joints. He has a vast experience with advanced surface analytical techniques such as Electron Microscopy (SEM, TEM, and FIB), AFM, XRD, Tribological testing, Corrosion and Nano-hardness tester.
