      abstract     = {Tungsten-chromium-yttrium (WCrY) smart alloys are foreseen
                      as the first wall material for future fusion devices such as
                      Demonstration Power Plant (DEMO). While suppressing W
                      oxidation during accidental conditions, they should behave
                      like pure W during plasma operation due to preferential
                      sputtering of the lighter alloying elements Cr, Y, and W
                      enrichment of the surface. In this paper, the erosion
                      performance of WCrY and W samples simultaneously exposed to
                      deuterium (D) plasma with the addition of $1\%$ of the
                      projectile ions being argon (Ar) ions at an ion energy of
                      120 eV is compared. With reference to the previous
                      experiments at 120 eV in pure D plasma, the erosion for both
                      WCrY and W is enhanced by a factor of ~ 7. Adding Ar to
                      the D plasma suppresses significant W enrichment previously
                      found for pure D plasma. To investigate the impact of the
                      plasma exposure onto the oxidation performance,
                      plasma-exposed and non-exposed reference samples were
                      oxidised in a dry atmosphere. Results show, on the one hand,
                      that the oxidation suppression of WCrY in comparison to pure
                      W is preserved during the plasma performance. On the other
                      hand, it becomes evident that edge effects imposed by the
                      geometry of the samples used in plasma experiments play a
                      significant role for the oxidation behaviour.},
