Corrosion of Silver Plated Contacts
We have a small brass electrical component to be silver plated to about 1.5 microns. We have given an undercoat of copper to about 1 microns.
My question is these components in the field develop heavy corrosion products after about a month or so. On examination of these samples, the corrosion products are blue in color (copper sulphate?) How do we avoid this?KUMAR.B.SHAH

Looks like you need at least a couple of microns of nickel layer between copper and silver to prevent copper diffusing into silver or vice versa.Mandar Sunthankar
