How to plate onto Titanium

-----

I NEED TECHNICAL INFORMATION ON ELECTROPLATING PURE GOLD AND PALLADIUM ONTO PURE TITANIUM. I UNDERSTAND THAT YOU HAVE TO CLEAN TITANIUM AND YOU HAVE TO PROTECT THE SURFACE FROM OXIDIZING AGAIN BEFORE ELECTROPLATING. CAN ANY ONE HELP WITH A PROPOSED CLEANING PROCESS AND PLATING CYCLES. THANK YOU

Hi, Roy. ASM International's "Metals Handbook--Volume 5: Surface Engineering has an outstanding chapter on how to plate onto titanium and other hard to plate metals.

In addition, one method I know of is to nickel plate and then heat the object to diffuse the nickel into the titanium. Letters 278 and 26878 offer some details on that. Good luck with it.
