I am working on finding the possibilities of obtaining thick ceramics coating layer by using Aerosol Deposition method. My primary responsibilities are setting up an Aerosol Deposition facility, optimising the process parameters for a good coating layer, investigating the mechanism behind the coating process.

My research work was to find out the local strain rate sensitivity of High strength low alloy steel having a gradient microstructure at different region from UFG structure to coarse grain structure. I have used nano-indentation test, with both strain rate jump test and contestant strain rate method. Primarily looking at the Dependance of strain rate sensitivity on grain size.

The objective of this dissertation work is to develop sustainable fabrication routes for ceramic materials by utilizing electric field-assisted sintering technologies. Specifically, the influence of electric field and current on the densification behaviour and microstructure evolution of doped Ceria was studied. Optimization of the sintering parameters for doped ceria powders and tailoring the microstructure by controlling the material synthesis and processing conditions were investigated.
