摘要：

Applying protective coatings on metallic interconnects are being considered as the most effective approach to improve the metal endurance in solid oxide fuel cell (SOFC) technology. The importance of a high green density to improve the sintered density and various properties of sintered ceramic materials is also well-known. In the present study, electrophoretic deposition (EPD) of (Mn,Co)(3)O-4 powder in iodine-added ethanol suspension was studied under constant voltage (50 V) and concentration (10 g.l(-1)). The packing behavior of green layers was investigated during deposition. An increase in solid fraction participating in the coating layer was observed with deposition time, showing that the microstructure of the deposit becomes more close-packed when EPD is prolonged. A kinetic relation based on density-time proportionality was proposed regarding the mechanism of packing of particles during EPD. (C) 2012 Elsevier B.V. All rights reserved.
