Zinc vs. nickel plating - Finishing

A nickel coating must be free of pinholes and porosity to function because the steel tries to galvanically protect it, so you will get rust blooms at any pinholes in the nickel. This also means that zinc coating …


Electroplated Zn-Ni coatings also have good throwing power to better coat blind holes and recesses. Zn-Ni alloy coatings are usually composed of approximately 85% zinc and 15% nickel and quite often are used as a base layer under trivalent chromium. zinc nickel plating typically has a dull gray finish in its alloy form but can be chromated to a black zinc finish.
