RE: Conductor Roll -- Copper Coating
Hi Stephen,
We have a video from around the 1960's (maybe 1970's judging by the hair styles of the operators) of this exact application being done by our service division at the time.
We arc sprayed copper up to 30mm thick after a bond coat was applied. The rolls were linished, copper plated, ground, chrome plated and finally ground again. It may be that with todays arc spray and grinding technology, the middle copper plating process could be skipped.
If you're interested, I can have a go at extracting that section of the video and emailing it to you.
