Plasma Sprayed Tungsten-based Coatings and their Usage in Edge Plasma Region of Tokamaks

Popis výsledku v původním jazyce

Tungsten is a candidate material for plasma facing components for ITER and other fusion devices. Plasma spraying is among prospective fabrication technologies, thanks to its ability to coat large areas and the possibility of in-situ repair. Several typesof tungsten-based coatings were produced at IPP Prague, using water-stabilized plasma spraying. Their structure, porosity, oxide content and mechanical and thermal properties were characterized. Several stages of the spraying process optimization towards the foreseen application were performed. The usage of these coatings as plasma facing materials (covering different diagnostic tools) in the edge plasma region was tested at the CASTOR tokamak at IPP. Behavior of 0.4-2 mm thick plasma-sprayed surfacesand their influence on the discharge quality was studied. Plasma sprayed tungsten-based samples, solid tungsten and graphite were inserted into the plasma at various radii and exposed to tokamak discharges (30 ms pulse length, 30 kW.
