dc.description.abstract | Herein, electroreduction in yttria-stabilized zirconia are investigated by means of Hebb-Wagner
polarization experiments. By performing optical and thermal microscopy on single crystals and thin
films during the application of an electric field under vacuum or oxygen-tight sealed conditions, the
movement of the reduction front from the cathode to the anode, which causes a blackening of the
material, is monitored. When performing electrocoloration experiments on thin film samples, the
progressing reaction of the blackened region was found to be inhomogeneous and evolves as a
dendrite-like finger structure. The progression of the blackening fingers follow preferentially the
electric field lines and thus are influenced by distortions in the field that can be caused by metallic
particles embedded in the oxide. In contrast to this, in the first stage of the reduction process no
significant influence of mechanically-induced dislocations on the morphology or kinetics on the
electroreduction can be found. Only after a heavy electroreduction was a localized transformation of
the surface region observed. There is an evolution of highly oxygen deficient ZrOx regions, which have
a characteristic checked topography pattern at the microscale level. | pl_PL |
