摘要

The electrophoretic deposition (EPD) process is one of the ceramic powder assembling technologies. This technique has some advantages compared with other fabrication techniques in terms of the fabrication costs and the structural flexibility of the substrates. A solvent that has high relative dielectric constant is usually used as an EPD bath. In case of using organic solvents, high voltage is applicable to the EPD bath and the particles can migrate under the strong driving force. However, most of organic solvents have difficulties in practical use because of their flammability. In this study, we investigated the technological feasibility in preparation of various ceramic coatings by the applied high voltage EPD in a non-flammable organic solvent such as hydrofluoroether (HFE). We found that nonflammable HFE was useful for the EPD bath for the preparation of various oxide coatings. Ceramic powders, such as yttria-stabilized zirconia (YSZ), zeolite A4, silicalite, mesoporous silica (MPS) and silica powder could be deposited on the metal substrate under the applied voltage at 100V. In addition, the use of HFE can reduce the electric power consumption to 1/10000 or less compared to the use of organic solvents such as alcohol and acetone.
