Fig. 6From: Controlled Fabrication of Nanoporous Oxide Layers on Zircaloy by Anodization a FESEM image of a a nanoporous and b a nanotubular ZrO2 layers fabricated at different water content of a 0.5 and b 10 wt% in an electrolyte, respectively. Both oxide layers were prepared by anodization of zircaloy in ethylene glycol containing 0.3 wt% NH4F at 90 V for 10 minBack to article page
