Hi, Robert. Unfortunately, the simpler a question is, the harder it usually is to answer it because we then have to try to account forevery possibility. But the best way to get black nickel is to have the plating shop electroplate black nickel rather than to try blackening processes as field options. Is that a good answer for your situation or a bad one?
