Plating on Nickel / Titanium Alloy




We have recently begun trying to Gold plate a dental wire insert that is made of nickel-titanium. Our customer does not know what the percentage of nickel is and we are in the process of determining the composition. In the mean time, does anyone have a good process for plating on this type of alloy?

Since it is for a medical application I would suspect that your nickel-titanium alloy is Nitinol which is a shape memory alloy that is 50% Ni and 50% Ti. Titanium oxide is the main surface contamination on these alloys. This will have to be removed before plating the gold.

I am highly familiar with this process. I have 11 years experience plating these exact same items. It requires a dedicated set up line including a acid gold strike, and ammonium bifluoride for oxide removal.
