Area of work:
Development of joining technique for the Plasma Facing Components (PFCs) of ITER like tokamak and future DEMO relevant divertor application. This includes joining of Tungsten (W) to Tungsten alloy (WL10), WL10/SS, SS/CuCrZr and WCu/CuCrZr by diffusion bonding and vacuum brazing routes. Materials testing and characterization using Gleeble 3800 system; In-house test mockup fabrication such as medium scale water-cooled DOME, reflector plate and Tungsten monoblock mockup and its qualification such as metallography, mechanical test (shear, hardness) and thermal fatigue test etc. Thermal and electrical property measurement of the material & joint samples using Laser Flash Thermal conductivity unit and using four probe resistivity measurement setup; Coating of various target materials (W, Cu, Cr, Graphite etc.) on selective material (substrate) surface by using RF magnetron sputtering unit. Other than divisional works - joining of Inconel 625 to Inconel 625 material using diffusion bonding and high temperature vacuum brazing technique for Recuperator application.
