Curious about electroless nickel in vacuum applications

I'm looking for data on the performance of Electroless nickel plating in high vacuum. Has anyone experienced flaking after certain period of time in high vacuum? How badly does the Electroless nickel coating outgas during pump down?

Electroless nickel is our plating of choice for vacuum applications (or gold). We have had electroless nickel plated surfaces under high vacuum in life test for over ten years.
Pure tin has problems of whisker growth under vacuum.
Cadmium and zinc are subject to sublimation under vacuum.
