Abstract
An apparatus for electrolytic surface treatment of goods comprises a tank for the acceptance of a treatment bath, an arrangement for contacting the goods with one pole of an electrical source, at least one electrode arranged in the treatment bath having an opposite polarity to the polarity of the one pole which is contacting the goods being treated, a vibratory conveyor having a helically ascending conveyor track for transporting the goods through the tank, characterized by the electrode being a helically shaped electrode being positioned to be equally spaced from the surface of the conveyor track. The apparatus is particularly useful for the electro-deposition of aluminum from aprotic, oxygen-free and water-free, aluminum-organic electrolyte.
