Hi Christian
Electrolytic method:
20% sodium carbonate
5% tartaric acid
75% water
temperature 70-80 degree C
Stainless steel cathode, coated part anode
current density 4-8 amps/sq in @ 6 volts DC
The nickel strip salt solutions I was referring to are commercially
available chemicals primarily designed for removing electroplate
and electroless nickel coatings from steel. I have come across
cyanide based solutions containing Enstrip A plus Enstrip T-L and
Enstrip S plus sodium cyanide. Plating chemical supply companies
like

may be worth looking at. These are effective with nickel based
coatings, but believe chromium interferes, so may not work well
with Diamalloy 2001. Do a search for say "stripping" on the search
message board search facility and you should find a few other
message threads on this general subject.
Regards Gordon
