Anode and high-speed plating machine provided with the same

Abstract

Providing an anode capable of desirably performing plating for a long period of time. An anode is cylindrical and forms a space between an article to be plated and itself. A plating solution flows in the space. Positive voltage is applied to the anode. The anode includes an outer cylinder and an inner cylinder welded to be in contact with an inner surface of the outer cylinder. The inner cylinder is formed of a plate material made from platinum.

1 . An anode which is cylindrical and forms a space between an article to be plated disposed therein and itself, in which space a plating solution flows, wherein positive voltage is applied to the anode, the anode comprising:
 an electrically conductive outer cylinder; and   an inner cylinder welded to be in contact with an inner surface of the outer cylinder, the inner cylinder being comprised of a plate material made from platinum.   
     
     
         2 . The anode according to  claim 1 , wherein the outer cylinder and the inner cylinder are formed by overlapping and welding a flat plate material made from titanium and a flat plate made from platinum and bending the welded flat plate materials into a cylindrical shape with the flat plate material made from platinum being located inside. 
     
     
         3 . A high-speed plating machine comprising:
 an anode defined by  claim 1 ;   a power-supplying member brought into contact with an article to be plated to apply negative voltage to the article;   a circulation unit configured to circulate a plating solution so that the plating solution flows between the anode and the article disposed in an interior of the anode; and   a power supply unit configured to energize the article via the anode and the power-supplying member.   
     
     
         4 . A high-speed plating machine comprising:
 an anode defined by  claim 2 ;   a power-supplying member brought into contact with an article to be plated to apply negative voltage to the article;   a circulation unit configured to circulate a plating solution so that the plating solution flows between the anode and the article disposed in an interior of the anode; and   a power supply unit configured to energize the article via the anode and the power-supplying member.
