Abstract: The invention relates to an anode assembly for electroplating comprising (a) an anode body comprising soluble anode material and (b) a shielding covering at least part of the anode body and comprising a self-passivating metal electrically connected to the anode body and allowing electrolyte transport therethrough. The shielding comprises at least one layer of self-passivating metal having no openings larger than 2 mm, preferably 1 mm, in width or the shielding comprises at least two layers of self-passivating metal wherein the openings of at least one layer are at least partially covered by the metal of another layer. The invention also relates to a shielded anode basket, a method for electroplating and the use of the anode assembly and the shielded anode basket.
