ABSTRACT:
An electrodeposition coating system widely used in an automatic coating process of a motor vehicle and the like. This system comprises: an article to be coated as being a first electrode, which is disposed in an electrodeposition bath; and at least two second electrodes provided in association with the article; and current is passed between the both sets of electrodes through an aqueous solution of a substance for forming a coating film contained in the bath to thereby electrodeposit the substance onto the article. The second electrodes consist of two groups of electrodes, the electrodes of a first group out of these second electrodes include electrode members constituted by corrosion-resisting members, each of these electrode members is integrally provided with a first membrane position therearound for precluding most of the flow of an ionized neutralizing agent contained in the aqueous solution, which is attracted by the electrode members, and the electrodes of a second group include electrode members which are each integrally provided with a second membrane portion therearound, for osmotically extracting the neutralizing agent.
