Basket-type anode

Abstract

A basket-type anode stores plating pellets in a plating bath and is used for electrolytic plating of a steel strip. The basket-type anode comprises a reticulated member made of Ti to be placed facing the steel strip. The reticulated member contains one or more platinum group elements. When the reticulated member contains one or more platinum group elements, the corrosion of the reticulated member can be prevented, and the lifetime of the reticulated member can be improved.

1 . A basket-type anode for storing plating pellets in a plating bath and being used for electrolytic plating of a steel strip,
 the basket-type anode comprising a reticulated member made of Ti to be placed facing the steel strip,   wherein the reticulated member contains one or more platinum group elements.   
     
     
         2 . The basket-type anode according to  claim 1 ,
 wherein the amount of the one or more platinum group elements contained is, in mass %, 0.01% to 0.15%.   
     
     
         3 . The basket-type anode according to  claim 1 ,
 wherein the reticulated member further contains one or more of Ni and rare earth elements.   
     
     
         4 . The basket-type anode according to  claim 3 ,
 wherein the amount of the Ni contained is, in mass %, 0.2% to 1.0%, and the amount of the one or more rare earth elements contained is, in mass %, 0.0005% to 0.020%.   
     
     
         5 . The basket-type anode according to  claim 1 ,
 wherein the reticulated member further contains, as one or more impurity elements, in mass %, Fe: 0.3% or less, O: 0.35% or less, C: 0.18% or less, H: 0.015% or less, N: 0.03% or less, Al: 0.3% or less, Cr: 0.2% or less, Zr: 0.2% or less, Nb: 0.2% or less, Si: 0.02% or less, Sn: 0.2% or less, Mn: 0.01% or less, Co: 0.35% or less, and Cu: 0.1% or less, amounting to 0.6% or less in total.   
     
     
         6 . The basket-type anode according to  claim 1 ,
 wherein the plating pellets are Ni particles.   
     
     
         7 . The basket-type anode according to  claim 1 ,
 wherein the plating bath is a Watts bath.
