Box 3640,76021 Karlsruhe∗r.krug@fz-juelich.deKeywords: Powder Injection Moulding, Tungsten, Deuterium Retention, SputteringTopic: Plasma-Facing ComponentsType of Submission: TalkPowder Injection Moulding (PIM) is a promising technique for altering materialproperties of tungsten as a first wall material for nuclear fusion through dopingwith different elements (e.g. titanium carbide) and mass-producing complex shapedparts.The resulting changes in microstructure improve the mechanical properties, but canhave effects on the plasma behaviour like erosion and fuel retention as well. Inpreliminary studies it was determined, that especially preferential sputtering of thealloying particles and the plasma interaction with the carbon based binder have themost impact on the plasma behaviour of PIM tungsten alloys.In this work, we investigate the behaviour of the surface near region (first fewμm)of 6 different PIM produced tungsten alloys under deuterium plasma exposure. Forthis, the samples are exposed to a deuterium plasma with a total fluence of≈5×1025m−2s−1at a temperature of200◦Cin the linear plasma device PSI-2.The surface modifications due to the plasma are investigated by Focussed Ion Beamand Scanning Electron Microscopy (FIB-SEM), the change in material compositionby Secondary Ion Mass Spectrometry (SIMS) and the deuterium depth concentrationin the first fewμmby Nuclear Reaction Analysis (NRA) |
