PROCESS AND DEVICE FOR ELECTROCHEMICAL SURFACE TREATMENT OF ELONGATED METAL PRODUCTS

摘要

ABSTRACT OF THE DISCLOSURE: A method and an electro-chemical treatment system in static or the parade of the surface of metal products of elongate shape. The method is characterized in that sets within the same volume of electrolyte from the cathode and anode areas separated from each other, and which move parallel to cyclically product. This method is implemented in a cell a single compartment in which there are at least four elec-trodes two of which are under electric voltage. This inven-tion is particularly applicable to aluminum, magne-sium, titanium and their alloys in order to treat regularly the entire surface of the product.
