in the range of 0 01 ma to 0 5 ma per mg anode mass in which case the voltage will rise from slightly below or equal to the dielectric formation voltage to a limit which is set by the operator the process can also be carried out at constant voltage as discussed hereinabove in which case the current must be capped to prevent it from rising to the level that will destroy the dielectric coating the electrophoretic impregnation process if carried out long enough will simultaneously produce an outer conductive polymer coating on the surface of the anode after which conductive carbon and silver coatings known in the art may be directly deposited onto the outer conductive polymer coating in the second embodiment referred to above a thick outer conductive polymer coating may be formed with any cathode material either polymer or inorganic by epd on an anode previously impregnated by any of the methods known in the art or by epd in accordance with the first embodiment of this invention in one embodiment of the coating process the temperature of the emulsion of conductive polymer during immersion of the anode in the edp cell is between 5 u00b0 c and 50 u00b0 c and the anode is immersed for a period of time ranging from 1 second to.
