Bluing

No. Nickel plating forms a non-porous surface that bluing will not react to. The plating must be stripped off before you can blue. Another possibility if stripping the nickel is not an option would be a coating such as gun kote. The downside would be the thickness of the coating on top of the nickel may affect certain tolerances. In those cases you would have to sand down the coating and hope the proper clearances are achieved.
