Zinc Nickel Plating Thickness

The process is rack plating.

Zinc nickel plating thickness.

The zinc plating process can be considered an excellent primer for paint surfaces with the paint protecting the zinc giving a lasting protection. There are a stream of zinc nickel applications for the automotive electronic aerospace and defense industries. For comparison zinc plated and passivated parts of a similar thickness are expected to achieve only 120 hours considerably less. Interpreting thickness and salt spray specifications for zinc nickel plating march 21 2013.

X ray fluorescence xrf is a common technique used for quality control of zinc and zinc nickel alloy plating deposits. For some applications designers may opt to use zinc nickel plating instead of zinc plating for further corrosion resistance the above table will not be applicable. Is 8 microns minimum. For zinc nickel plating what should be the correct criteria to determine the correct plating thickness.

It can be formulated to meet a variety of corrosion resistance specifications. We do not recommend powder coating. What are the xrf testing requirements for plating zinc nickel alloy. To shed more light on our zinc plating thickness issue most of our in house thread ring gages are class 2a gages.

Accurate thickness measurement for both alloy deposits can be obtained using proper thickness standards. Cast iron requires nickel underplate thickness. In the past we have attempted to produce threads to a undersize pitch diameter less 4 times plating thickness and use the 2a gages to check afterplate condition. Zinc plating with black chromate offers better corrosion resistance and anti galling characteristics than black oxide.
