Surface Preparation of Nickel Cobalt

[vtmys]

I have been conducting some research on the surface preparation of Nickel Cobalt alloys for adhesive bonding. I am looking to try other surface preparation techniques aside from concentrated Nitric Acid. If anyone has any recommendations, please let me know.

Thanks,

Can you use an abrasive blast on the NiCo alloy.

What is the alloy?
This might help with an etchant.

What type adhesive are you using?

vtmys:

I've never done this with NiCo alloy but you might try Sodium or Ammonium Bifluoride solution at about 140F.
