Gold Stripping on Titanium Substrate

I want to know how to strip a gold layer on titanium substrate after PVD which do not attack the Ti surface and can maintain the origin color. If you have any suggestion, please give me a comment.

Thank you very much for your help.

Acidified Thiourea ⇦ on eBay or Amazon [affil link] at a controlled voltage will strip gold from Titanium without effecting oxidation color. Commercial processes are available.
