The SEHt Group, headed by Dr. Hosmani, is dedicated to understanding the severe surface deformation and surface alloying of various ferrous and nonferrous alloys. Our group attempts to study the effect of surface engineering on the microstructures and properties (mechanical, tribological, and corrosion) of the alloys. For such a study, our group frequently uses the characterization tools like SEM, EBSD, XRD, GDOES, EPMA, Raman spectroscopy, microhardness, nanoindentation, pin-on-disk tribometer (dry, lubricated, and high temperature), etc. Our group also focuses on coatings to enhance the tribological properties of alloys.
If you are interested in our group for collaboration or PhD research, feel free to email Prof. Santosh Hosmani (Email: sshosmani [AT] iiti.ac.in). We are open to institutions for collaborative studies. We look forward to collaborative opportunities that drive innovation in surface engineering.
