My research interests are in the broad area of machining, grinding and cutting tool coating. I currently lead a group of students who are working on research problems as diverse as (i) finishability of oxide ceramic plasma sprayed coatings, (ii) development of diamond reinforced tribological thick coating and finishability of such coatings, (iii) high speed grinding of ceramics and carbon fibre reinforced ceramic matrix composites, (iv) environment friendly near dry micro-machining, (v) high speed grinding of aerospace metallic materials, etc. We are also interested in initiating work in the area of (i) development of tribological hard coating through plasma transfer arc processing, (ii) finishability of such coatings, (iii) machinability and grindability of additive manufactured components, (iv) additive manufacturing through GMAW, GTAW and PTAW.
The SEM and XRD facility at the Department of Mechanical Engineering, IIT Kharagpur is open to academic institutes and industry against payment. SEM is fitted with EDX analysis facility. The XRD can undertake phase scan and analysis, residual stress measurement, GI-XRD for thin films, micro-diffraction, and GI-XRD stress measurement in thin films. contact: spaul@mech.iitkgp.ernet.in.
