Measuring zinc nickel plating thickness when electroless nickel is below it



June 1, 2010

Q. Dear SIR,

We are a connectors company.
We are in the phase of developing zinc nickel plating over aluminium -- with electroless nickel as undercoat, and with top coat of zinc nickel with black passivation layer on top. I want to know the thickness of nickel as well as zinc nickel layer along with %. But as zinc nickel bath contains nickel so on final layer nickel from electroless nickel as well as from zinc nickel mix and reading will be wrong.

Pl. guide us on above matter.

A. Depth Profiling using Glow Discharge Spectroscopy is the perfect technique for what you are looking at. LECO company sells these instruments but they are pricey.
