Although zinc in nickel are used in different ways within industrial plating processes, hallowing the two metals together provide significant benefits. In particular, this zinc-nickel alloy plating provides greater corrosion protection than when only zinc is used. The addition of nickel reduces the speed of the zinc corrosion process. In addition, top coats and passivation treatments can be applied to enhance the long-term performance of the finish. The alloy of zinc-nickel often consists of about 80 to 94% zinc and 6 to 20% nickel.
Zinc-Nickel Alloy Plating in the Automotive Industry
Use considerably the automotive industry, zinc-nickel plating produces corrosion resistance for various automotive components. When plating with zinc-nickel, and acts as a sacrificial coating and undergoes corrosion before the underlying base that will Corrodes. Salt spray testing of zinc-nickel coated parts demonstrates that they can resist the development of red rust for 1000 hours and white cross for as much as 500 hours.
When parts come in contact with aluminum, zinc-nickel plating is preferred above standard zinc plating. The corrosion processes slowed significantly through the application of zinc-nickel plating. This alloy is also more capable of operating under higher temperatures that develop inside of automotive engines than other types of zinc alloys, in particular zinc-iron, or zinc-cobalt.
Other Industries Utilizing Zinc-Nickel Alloy Plating
Other industries that utilize zinc-nickel and their applications include the aircraft manufacturing industry and the electrical transmission industry, specifically for its use of coaxial cables, anchors, and cleat bolts. In addition, the defense and aerospace industries have put confidence in zinc-nickel plating as a suitable replacement for cadmium plating.
In addition, this alloy is used to a considerable degree as the tubing for hydraulic and fuel components and parts. Other applications involving zinc-nickel plating include commercial transportation vehicles, such as light trucks, tractor trailers, and buses, in addition to the manufacturing of railway and firefighting equipment.
Additional Benefits of Zinc-Nickel Plating
The deposits of zinc-nickel coating are considerably bright which makes the alloy ideal for the production of attractive finishes. This type of plating reduces the formation of whiskers, thin metal strands that can impose damage to a finished material. You can obtain excellent surface coverage and uniform plate distribution through this alloy plating. Zinc-nickel alloy plating can deliver deposits that have no blisters as well as excellent adhesion.
