Preparation of YSZ/Al2O3 composite coatings via electrophoretic deposition of nanopowders
Using electrophoretic deposition (EPD), we have produced YSZ individual ceramic coatings and YSZ/Al 2 O 3 composite coatings for a wide range of applications in modern materials research. YSZ and Al 2 O 3 nanopowders were prepared by high-energy physical dispersion techniques, namely, by a laser eva...
