electrochemical treatment of parts, possibly in different branches of machine engineering. SUBSTANCE: two cathode washers 35,45 are designed for making recesses in blank 55. Electrolyte flows along said washers. Duct 23 for back flow is parallel relative to feed opening 12 and it allows to draw back electrolyte flow opposite relative to its feed direction. Gaps 53, 54, 38, 39 at both sides of cathode washers 35,45 are different. By selecting shape and radius values of cathode washers, it is possible to make non-uniform shape contours. Electrode 10 allows to electrochemically treat blanks for creating profiled contours of special shape and to treat several contours by one operation. EFFECT: improved design of apparatus providing enhanced efficiency of treatment process. 9 cl, 5 dwg
