Abstract

The results of studies of the zeta potential, pH, and electrophoretic deposition (EPD) characteristics of Ce0.8Sm0.2O1.9 (SDC-m) micropowder suspensions with SDC-n nanoparticles added in different proportions are presented. It is shown that a suspension of microsized particles is stabilized due to the introduction of highly charged nanoparticles. The thickness of the coating changes nonmonotonically during the EPD from an SDC-m/SDC-n suspension at higher contents of SDC-n nanoparticles, while the zeta potential and resistance of the suspension tend to increase. It is shown that the greatest thickness of a continuous and homogeneous SDC coating is achieved at a 5 wt % content of SDC-n nanoparticles.
