Document Type and Number:

Japanese Patent JP2573220

Kind Code:

B2

Abstract:

It is provided in an electrochemical polishing and pickling method and apparatus for treating metal surfaces that an electrolyte stream (18) entering a casing (12) is divided into an anodic partial stream (20) and a cathodic partial stream (22). The anodic partial stream (20) flows past a dielectric wall (32) as well as the surface (10') to be polished or pickled, while the cathodic partial stream does not reach the surface (10') to be polished but instead is recycled directly into an electrolyte reservoir (30) after having passed the cathodes (24).
