Head Member For A Current Bar For Use In Electroplating Apparatus

Abstract

Method and apparatus for reducing corrosion of a current bar in a corrosive environment. The non-reactive metal is fused around a reactive metal creating a shell and reducing the corrosion of the reactive metal.

I claim: 
     
         1 . An apparatus for conducting a current and reducing erosion comprising a conductive metal fused with a non-reactive metal. 
     
     
         2 . An apparatus according to  claim 1  wherein the conductive metal is copper. 
     
     
         3 . An apparatus according to  claim 1  wherein the non-reactive metal is titanium. 
     
     
         4 . An apparatus according to  claim 1  wherein the conductive metal has an outer surface and the non-reactive metal creates a shell fused with the outer surface of the conductive metal. 
     
     
         5 . An apparatus according to  claim 1  wherein the combination of the fused non-reactive metal to the conductive metal reduces corrosion of the conductive metal in a corrosive environment. 
     
     
         6 . An apparatus according to  claim 1  wherein a portion of the non-reactive metal shell is removed from the outer surface exposing the conductive metal for connecting with a power source 
     
     
         7 . A method for replacing a corroded metal head comprising:
 removing the metal head from the current bar;   attaching a new head member to the existing current bar by first welding the conductive metal of the head member to the conductive metal of the current bar, using a conductive metal to weld the members; and   welding the non-reactive metals of the head member to the non-reactive metal of the current bar using a non-reactive metal for said welding.   
     
     
         8 . A method for reducing corrosion in a current bar immersed in a corrosive environment comprising:
 a) fusing a conductive metal member with a non-reactive metal shell eliminating any exposed surface of the conductive metal;   b) creating an exposed surface of the conductive metal member to form a head member;   c) connecting the exposed surface of the metal head member with a power source;   d) operating the current bar in a corrosive environment.
