I would like to find out what procedures are in use to apply a flash electroplated finish of copper, tin or nickel to a nickel-chromium electrical resistance alloy. I'm told that this requires extremely harsh activation chemistry. What type of chemistry? Henry Ford said "If you need a tool and do not buy it, you will pay for it anyway"

There is a relatively new method called direct metalization which seeds a cunductive polymer to the hole to carry the electroplating current. This replaces the classical platinum seeding method.
 
Hi SethN
Thanks for the reference. Direct Metallization is new to me. Can you suggest a place to go for more process data? Also, you mention a hole. What did I miss? Are you referring to a site on the cathode's topology where bonding will occur?

I may have pointed you in the wrong direction, my apologies. Direct metalization is a process in printed circuit board fabrication. The technology may have other applications however. For an overview see:
