Fig. 9From: Wetting and adhesion properties of quasicrystals and complex metallic alloysDirect observation of the alumina layer grown on a i-ACF sample by heat treating at 500 °C in air for 144 h. The upper surface of the oxide is marked by gold nanoparticles before preparation of the thin foil, to make it easier to identify. The thickness is found around 35 nmBack to article page
