Abstract

A method for electrochemical surface treatment of metal parts by immersion in at least one treatment liquid contained in at least one treatment tank (1), and a tank and machine for carrying out this method, comprising at least one electrolytic step in which said parts are received on a rotary structure (3) provided with receiving means (15) and rotatably mounted iabout a horizontal shaft (5) inside said treatment tank (1), potential differences (V1, V2, V3) are established between said parts and a plurality of electrodes (C1, C'1; C2, C'2;C3, C'3) arranged in said treatment tank (1), said parts being supplied with current of opposite polarity to that of the electrode via said receiving means (15) and said rotary structure (3), and said parts are completely submerged in said treatment liquid by a rotational movement of said rotary structure (3) bringing them successively to face the electrodes (C1, C'1; C2, C'2;C3, C'3). In particular, the spatial distribution of the electrical fields between said parts and said electrodes can be controlled by implementing masking means (16, 17, 18, 19, 20, 21, 22, 23, 29) disposed inside said treatment tank (1).
