Ingemar: What is the process you use for plating on to Kovar? This should work for Inconel as well.
The main issue, after you have gotten the Inconel clean, which could be a challenge, is to get it to plate without getting immersion Copper first, which would adhere loosely. In the "old days", platers got around the immersion plating problem by using alkaline Copper plating baths, such as Cyanide, or Pyrophosphate.
Since you also face the issue of immersion Copper on Kovar, whatever works for Kovar, would work well on Inconel.

Ted,
We used copper on this alloy in order to make it solderable.
I'm not very familiar with plating in detail, but as far as
I remember we used a nickel strike followed by sulphuric acid
sulphate copper bath. The plated copper was 50 micrometers
thick (yes, that thick!). Upon that a gold flash. The plating
company said it was a piece of cake.
We use copper plating even on aluminium and Kovar.

Ämne: [TN] Plating Copper on INCONEL
We are looking for how to plate copper on INCONEL (a Nickel Chromium
Iron alloy, the alloy we are considering is INCONEL 600). Anybody have
any suggestions?
