Electrophoretic Deposition

  • David BrandonEmail author


Electrophoresis is the migration under the influence of an electric field of charged particles held in a dispersion. Electrophoretic deposition (EPD) is then the deposition of these migrating particles onto a deposition electrode or porous membrane [1]. At a deposition electrode the charge on the particles is neutralized by the current flowing through the conducting electrode, while in a porous membrane it is the electrolyte in the part of the cell that is separated by the membrane from the dispersion that carries the neutralizing current. The two geometries are shown schematically in Fig.5.1. Deposition membranes are formed from a microporous non-conductor, while deposition electrodes have to have sufficient conductivity to carry the deposition current. In either case, the deposit closely follows the surface topology of the deposition electrode or membrane, and quite complex shapes have been produced which may either be detached from the substrate, as a freestanding component, or form an adherent surface coating.

This contribution was made possible through the efforts of the development team at Cerel – Ceramic Technologies Ltd., especially Martin Zarbov and Assaf Thon, whose efforts, over an extended period, have turned tentative speculation into practical demonstrations of technical and commercial feasibility.
