Composite plating - copper plating with graphite


(1996)

Does anybody have any information on cyanide copper plating with graphite? I've carried out a literature search, but everything seems to be out acid copper with alum oxide. Things I am interested in are, Type of graphite compatible with bath, surfactant systems if required to prevent agglomeration. Basically Anything!

It might be worth a call to Surface Technology in Trenton, N.J., USA. They do diamond co-deposition plating, license the technology, and seem to know most of what there is to know about codeposition out of dispersions.

Sender: could you please provide more information: Are you attempting to plate Copper from a Cyanide bath onto Graphite? Are you intending to use Graphite anodes? Or do you intend to co-deposit graphite? All three questions have vastly different answers.

I am looking to co deposit graphite, with copper(cyanide). There is a good review of Composite (particle co deposition) plating in the Journal of Applied Electrochemistry Vol 25 Pages 519 to 527, In it there is a reference to a paper By FINK & PRICE published 1928 on the production of cu/graphite bearings for the car industry - General Motors?, has anybody seen it?, is it worthwhile getting hold of? They used tannin & gelatin to stabalise there graphite suspension to prevent agglomeration.
