Abstract

The hardness of a metallic coating partic. silver plating on Cu wire is improved to as high as 150-160 its dia. to 15-20% of its original size, which cold drawing hardens the coating. The process is continuous and comprises passing the wire from a reel through scouring, rinsing, pre-plating, silver plating and rinsing baths in succession and finally cold drawing in a die, the wire then being re-wound on a take-up spool.
