Optimization of Electrophoretic Deposition of YSZ

Abstract

Electrophoretic deposition has acquired increasing interest for its outstanding potential to produce thick ceramic coatings on complex-shaped substrates. This makes electrophoretic deposition a promising technique to obtain ceramic coatings for several applications such as solid oxide fuel cells, thermal barrier coatings and biomaterials. Response surface methodology was used to model and optimize the electrophoretic deposition process. Three mathematical models were derived to understand the kinetics of electrophoretic deposition. The optimization results showed that applied voltage had significant effects on the packing density of YSZ particles.
