Using spray process in electroplating process

Posted by Raoul (216.64.111.82) on 21:26:22 18/01/06

Cathodic bars used in plating process need a coating to protect the copper substrate from corrosion and to provide a stripable surface when plating builds up. These bars are in acid copper plating solution with a small area exposed to carry current to the product, the balance of the copper bar is covered with plastisol. The exposed area requires a spray coating that will not corrode, have great transfer of DC current, provide low porosity and have a large micron surface texture to provide bonding of the plastisol coating. I know HVOF would work but what material/s are the most suitable. Thanks in advance for your help!
