Ni diffusion on Au under 800C

I'm now working for a MEMS devices which work under 600 C. 2 microns
electroless Ni and 2 microns Au are plated on Cu substrate. Some white
spots is observed after 600 C thermal testing. I guess that would be due to
metal diffusion. Would profession suggest a better diffusion barrier rather
than Ni?
