Cadmium plating on tungsten

I am trying to cadmium plate tungsten, and have had blisters and adhesion issues the whole time. I am using a nickel strike as my activation process. If anyone has any helpful info please let me know. I can use all the help I can get. Thanks

Hi, Tom

Tungsten is a refractory metal which is exceptionally difficult to properly activate for good adhesion. But the ASM Metals Handbook, vol. 5, has an entire chapter on the subject. Good luck.
