Document Type and Number:
Japanese Patent JP2629018
Kind Code:
B2
Abstract:
PURPOSE:To continuously perform stable plating of a roughened surface by feeding plating liquids through the flow paths which are formed between plating metal, an object to be plated and the partitions provided oppositely thereto respectively and thereafter joining the plating liquids, defoaming and circulating them. CONSTITUTION:The partitions (a), (b) opposed to both plating metal 7 and an object 3 to be plated respectively which are immersed in. e.g., plating liquid 2 are arranged between both and the flow paths R, S are formed between the partition (a) and the plating metal 7 and between the partition (b) and the object 3. The plating liquids A are fed to the flow paths R, S from a mixing tank 11 with pumps P respectively and DC current is allowed to flow between the metal 7 and the object 3 and electrolysis is performed while utilizing the metal 7 as an anode and utilizing the object 3 as a cathode. The plating liquids B, C which have been allowed to flow through the flow paths R, S along the metal 7 and the object 3 are overflowed to the outside of a plating tank 1 and introduced into the mixing tank 11 together with the plating liquid D dipped out from an aperture 9, joined, uniformized and defoamed and thereafter fed to the tank 1 as the plating liquids A. The change in the concn. of metallic ions incorporated in the plating liquids can be made little by this method.
