Silver plating on cobalt alloy

We are having an adhesion problem on the bottom of a blind hole when silver plating on a cobalt alloy. Is there anything different or special in the process when silver plating on a cobalt alloy?

Hi, Tim. My inclination would certainly be to believe that this cobalt alloy quickly forms a tenacious passive oxide film like stainless steel and nickel do, and requires, as they do, a Wood's Nickel Strike.
