Abstract
Deaggregated nonaqueous suspensions of ZrO2 nanopowders stabilized by Y2O3 (YSZ) with an average diameter of particles of 11 nm obtained by laser evaporation and condensation are studied using dynamic light scattering (DLS). Two types of suspensions with an average size of aggregates of 108 and 66 nm are obtained by ultrasonic machining (USM) and centrifugation. It is shown that the combination of USM and centrifugation allows us to obtain narrow size distributions for the particles in YSZ suspensions. Coatings are obtained using electrophoretic deposition (EPD) from two types of YSZ suspensions with different degrees of deaggregation, and it is shown that no difference in the structure and morphology of suspensions is observed. It is established that, by EPT of the particles, a mechanism of electrochemical coagulation is realized at the electrode from the suspensions with different degrees of deaggregation.
