Fabrication of Functional Coating Film with Controlled Microstructure by Electrophoretic Deposition Method

Application of electrophoretic deposition for inner surface coating of porous ceramic tubes

“…8. The pore size of the deposited alumina layer is smaller than 50 nm, which is small enough for removing bacteria whose size is in the range of 0.2-10 μm [18,23]. This pore size is too large to remove virus in air; however, a high ratio (N4-log) removal of virus in water has been achieved by a coagulation-filtration process using a membrane with the pore size of 0.1 μm [24].…”

“…Matsuda et al and Besra et al used a NiO-YSZ porous flat substrate with one side coated with a graphite or carbon sheet and obtained a YSZ deposit on the uncoated non-conductive side [15][16][17]. In the case of the deposition on non-conductive porous tubes, Hamagami et al obtained an alumina deposit on the outer surface of a porous alumina tube by arranging a noncontact cathodic Pt wire at the center of the tube and a noncontact anodic Pt mesh as the counter electrode at the outside of the tube [12,18] Their methods are to capture electrophoretically migrating particles on the surface of the porous substrate by a filtration technique. This method is useful, but the density of the deposits is sometimes inferior to that of the directly consolidated deposits on an electrode.…”

Effect of Low-Friction Composite Polymer Coatings Fabricated by Electrophoretic Deposition and Heat Treatment on the Ti-6Al-4V Titanium Alloy’s Tribological Properties

“…In the available literature, there are not many reports about the EPD of PTFE particles. Jang et al [43] co-deposited PTFE with hydrous ruthenium oxide from a mixture of ethanol and water, while Hamagami et al [44] used acetone solution with a small amount of water for the co-deposition of PTFE particles with titanium oxide. Liu et al [45] used cholic acid sodium salt as a dispersant for the deposition of PTFE particles onto stainless steel substrates.…”

Inner Surface Coating of Non-Conductive Tubular Substrate Using Electrophoretic Deposition

“…It can be used to apply deposits on flat, cylindrical or complex-shaped substrates. To obtain the layers on porous ceramic tubes, conductive materials such as Pt or stainless steel wire and cylindrical mesh as electrodes have been placed inside and outside of the porous tubes, respectively [4][5][6]. Though the coating of the outer surface of porous tubes using EPD technique has been widely reported, the coating the inner wall of the tubes is a challenge.…”
