Formation of Yttrium-Stabilized Zirconium Oxide Films Deposited from Suspensions

Abstract

Factors influencing the formation of dense and uniform films of stabilized zirconium oxide from alcohol-containing suspension precursors on anode substrates by dip coating technique, such as the microstructure of the initial electrolyte powder, deposition conditions, and suspension concentration, were studied. The optimum conditions (withdrawal velocity, suspension concentration, heat treatment conditions) for efficient deposition and forming of a ≈10 μm thick electrolyte film were determined experimentally.
