Zinc Alloy Plating
How do the zinc alloy plating systems Zn/Fe, Zn/Co, Zn/Ni and Zn/Sn compare with respect to corrosion resistance?Eric Gough

It is quite complicated, depending upon the application, so I would contact the vendors of proprietary plating solutions, and ask how their formulations compare. Even plating from the alkaline or acid bath will give you alloys with different properties.
A review of the literature will show several articles that study the differences.
Dear Mr Eric,
Mr Pullizzi is right, I do three of these except Zinc tin and don't know.
The Champ No 1 is : Zn Ni
Runner up No 2 is : Zn Fe
A poor Fourth is : Zn Co.
Note : I use Acid zinc cobalt so it wouldnt qualify for third place, I don't know about the Alkaline.
