| dc.description | In the present work, the objective is to develop a film deposition technique with
micrometric thickness. For this, the adaptation of a commercial inkjet printer was
done by designing and constructing a base with rails so that it runs over the
sample. At the same time, a study of rheological characterization of the
commercial inks, contained in original ink jet cartridges, was carried out for the
development and deposition of a ceramic suspension, which contains the
precursors of the desired material for the formation of the thin layer. Finally,
some depositions of SOFC electrolytes were performed, and after the
densification step, the cells were characterized by the impedance spectroscopy
and also scanning electron microscopy. It was observed the formation of a dense
and uniform layer, with thickness of the order of 10 ??m. | |
