Abstract

A method and a device are described for the electrochemical treatment of elongate articles, preferably bars. The article,is clamped at one end by means of a clamp,and is introduced into a hollow chamber that has a longitudinal axis, in an electrode,arranged in a dip bath with a periphery parallel to the axis, in as concentrically axial a manner as possible and is thereby directed through at least one axially displaceable, perforated screening mask,so that part of the area not to be treated electrochemically is screened from the electrode. The article and electrode are connected to a current source. A container,for treatment liquid has at least one electrode,therein, the electrode having a hollow chamber with a longitudinal axis and a periphery parallel to the axis. The article is introduced into the hollow chamber. At lease one screening mask,is axially adjustable within the hollow chamber and has openings for introducing the article. The mask can prevent electrochemical treatment of the article in specific areas. A current source and electrical connections are provided to the electrode and to the article.
