Plasma sprayed tungsten-based coatings and their performance under fusion relevant conditions

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 to repair damaged parts. This paper reports on the development of tungsten-based plasma sprayed coatings and their behavior under high heat fluxes and in tokamak plasma. Several tungsten-based coatings were produced using water stabilized plasma spraying. Their basic properties (structure, composition, etc.) were characterized. Their behavior under high temperature plasma conditions was investigated at the small-size CASTOR tokamak. The samples were inserted into plasma at various radii and exposed by standard plasma discharges. Mainplasma parameters, impurity radiation and specimen temperature evolution were observed. Only a local influence of the tungsten presence was found; no significant erosion was observed.
