Zinc Nickel

 Discussion:zinc nickel nov
With the advent of the environmental directives, ELV, WEE , and ROHS the metal finishing industry experienced a transition from the steadfast performance of hexavalent chromate conversion coatings to newly developed  compliant trivalent chromium passivation technology. It was recognized early on throughout many industries that standard commercial production zinc would not meet the requirements or performance needs of extended corrosion performance. Zinc-Nickel alloy emerged as a popular alternative to many previous zinc applications due to the alloys inherent corrosion performance over zinc. Electrochemically, Zinc Nickel alloy produces a different corrosion potential than either pure zinc or pure nickel alone. The corrosion potential is closer to steel and as a result, the alloy corrodes at a much slower rate than pure zinc electroplate alone, affording improved corrosion protection.

Why Choose Plating Technology for your Zinc-Nickel needs?

Over the past 3-5 years it seems all chemical suppliers to the metal finishing industry have a zinc nickel system available for sale and more plating shops are installing these systems into their facilities. It is important you choose an applicator who has a proven history of performance applying zinc nickel coatings and the on-site technical staff and ability to support the process. All alloy electroplates require application experience and increased technical knowledge for proper control and application of the finish compared to standard zinc electroplating. These alloy systems are typically marketed by the chemical supplier as systems which are as simple and problem free as standard commercial zinc electroplating processes, however there is a significant learning curve, to provide a consistent quality zinc-nickel alloy coating.
Plating Technology has been providing Zinc-Nickel alloy finishes to a variety of industries for the past 20 years.  We have the capability of providing both rack and barrel processing and the technical staff to provide guidance whether zinc-nickel alloy is the best selection for your specific application. Like any coating, zinc-nickel does have certain limitations depending on what environment or application it is placed in. Wouldn’t you feel more comfortable being a partner with a proven applicator?
