    • PROBLEM TO BE SOLVED: To attain a continuous plating without aging a plating liquid in an Fe-W alloy electroplating.
      SOLUTION: In the Fe-W alloy electroplating, an electroplating device of a two chamber structure separated into an anode chamber and a plating chamber with a cation exchange membrane is used to suppress the oxidative decomposition of an organic complexing agent comprised in a plating liquid at the anodes. Further, the continuous plating is performed without aging the plating liquid by jointly using two soluble anodes of metal iron and metal tungsten and replenishing an iron component and a tungsten component in the plating liquid in accordance with their precipitation quantities. Further, at the time of the plating and at the suspension of the plating, the plating liquid is brought into contact with metal iron to prevent the oxidation of bivalent iron ions into trivalent iron ions, thereby preventing the aging of the plating liquid.

    • 要解决的问题:在Fe-W合金电镀中实现不老化电镀液的连续镀层。 解决方案:在Fe-W合金电镀中,使用分离成阳极室的两室结构的电镀装置和具有阳离子交换膜的电镀室来抑制包含在阳极室中的有机络合剂的氧化分解 在阳极处镀液。 此外,通过共同使用金属铁和金属钨的两种可溶性阳极进行连续电镀而不使电镀液老化,并根据其沉淀量补充电镀液中的铁成分和钨成分。 此外,在电镀时和电镀液悬浮时,电镀液与金属铁接触,防止二价铁离子氧化为三价铁离子,从而防止电镀液老化。 版权所有(C)2006,JPO&NCIPI
