This article describes a technique which utilizes an electrophoretic deposition of a polymer coating onto a workpiece. Electrophoretic deposition is accomplished through the movement of suspended particles of polymer through a carrier fluid under the action of an electromotive force applied to electrodes in contact with the suspension. The fluid itself is determined by the chemical solubility parameters of the polymer being used and can be either a liquid or an atomized vapor. The workpiece, one of the electrodes in the fluid, is coated in a manner similar to that of conventional electroplating.
