ANODE FOR PLATING BATHS Russian patent published in 1998 - IPC

FIELD: electrolytic deposition of coatings, articular, deposition of copper or nickel coatings. SUBSTANCE: the offered anode is essentially a perforated container with bulk load through which perforated pipe runs for pumping electrolyte. Perforated pipe has distributing perforated branch pipes located at different heights. Pipe is connected with current lead and has lower and upper contact members. Walls of container and pipe with branch pipes are made of rigid dielectric, and container bottom and contact members are made of electric conducting material. EFFECT: higher rate of dissolving of anode material and its homogeneity due to stable and uniform distribution of electric potential over the entire volume of bulk load and reduced specific metal content of anode container. 3 cl, 1 tbl
