I concur with Jim. Instead of chemical plating try thin film coating. No Hydrogen present! Evap will keep temps below 125 degrees. Use plasma to sputter the surface and vacuum will extract most of the excess gasses if you leave it in long enough. Quite a set up for one project.
Steve,
I posted a solution for galling in another thread. thread338-52413 Galling on stainless steel thread under seawater condition. Try there!
