M. Tech. Metallurgical Engineering. / Studies the tribological and electrochemical behaviour of various WC-Co, WC-Co-Cr and CrC-NiCr based thermal sprayed coatings in synthetic mine water environment. The research aims to achieve the following objectives. 1. Characterize commercially available cermet powders used during thermal spray process. 2. Explore and understand the relationship between feedstock powder parameters, the phases and microstructures generated during thermal spray process. Study the interrelationship of feedstock powder chemistry and method of powder synthesis on wear and corrosion behavior of thermally sprayed coatings. Assess the joint actions of wear and corrosion behaviour of the coatings in synthetic mine water environment.
