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?

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.
