Zinc Cobalt with Olive Drab Passivation over Electroless Nickel

[pinguS]

Hi

My first in this forum, so unsure if I have selected the right page.

Just looking for anyone who can do the following process in the UK

Zinc Cobalt with Olive Drab Passivation over Electroless Nickel

I know of only one company so far, South West Metal Finishing, but I do not like putting all the eggs in one basket.

Is there anybody else. I found that Bodycote / West Middlesex cannot do the Zinc bit.

The supplier does need to have some sort of approval, i.e. Aerospace.

please can anyone advise...

I'm across the pond so I can't help directly but it does look like this is a somewhat rare process.
