XRF Testing Options for Zinc Nickel Measurements

The use of zinc-nickel coatings is not new to metal finishing but it has seen an increased interest in recent years because of the benefits it offers over coatings of only zinc and other zinc alloy coatings. The major benefits of zinc-nickel include its high resistance to corrosion, wear, and abrasion even at extreme temperatures. These characteristics result in a longer product life and, because of that, zinc-nickel has become the preferred plating in automotive and aerospace applications with specifications ASTM B841 and AMS 2417 being written for its use.

However, adding the typical 7% or 15% of nickel will drive the cost of the plating up anywhere from 1.5 to 2.5 times the cost of basic zinc plating...so do you improve plating efficiencies?
