HYBRID ELECTRODE FOR CHROME PLATING, CHROME PLATING METHOD USING THE SAME AND CHROME PLATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrode for chrome plating which is used even in high current density without using lead or lead alloy, and to provide a chrome plating method and apparatus using the same.;SOLUTION: A hybrid electrode 1 possesses a catalytic electrode element 2 having a catalytic function of converting 3-valent chrome to 6-valent chrome and a perforated electrode element 3 having a function of branching a part of plating current and having a circulation hole through which a plating solution flows, wherein the perforated electrode element 3 is arranged in the surface side having a catalytic function of the catalytic electrode element 2. The chrome plating method and a chrome plating apparatus use the hybrid electrode 1. The plating is carried out at high current density to increase the production efficiency because a part of the plating current is branched by the perforated electrode element 3 and the plating solution freely flows through the circulation hole of the perforated electrode element 3.;COPYRIGHT: (C)2008,JPO&INPIT
