With the performance criteria for various plated components becoming more and more demanding, directives have been established to ensure that environment considerations are met, which has created a number of changes in the surface finishing industry. The field performance that has resulted is as varied as the available alternatives. Here you will find out how zinc nickel alloy plating compares to dip spin coating technology in regard to a number of automotive component applications. This includes contact with other metals, the total friction co-efficient and corrosion resistance are all important properties that are highlighted here.

Corrosion Performance of Zinc Nickel Alloy Plating

There are over 100 different types of electroplated alloy processes, which date back to 1841. The benefits of zinc nickel alloy plating include the following:

* A number of new phases that were not present on the metallography phase diagrams are able to be achieved.
* Homogeneous alloy compositions that are not attainable with the standard melting methods, due to the low melting point metal that vaporizes when it reaches the temperature of the higher melting point metals.
* The thin deposits of film coating will offer high performance features.

Some of these features that are offered by the thinner film coating include: increased stability of the corrosion by-products; a lower dissolution rate in corrosive atmospheres; an adherent conversion film; and the ability to corrode sacrificially to any steel.

The Corrosion Rate of Zinc Nickel Alloy Plating

The substrates are actually protected via the plating deposition of the zinc and the zinc alloys. Because of their poor ionization, both zinc and the zinc alloys are able to sacrificially dissolve before the actually substrate.

The Proven Track Record of Zinc Nickel Alloy Plating

There is no question that the zinc nickel alloy plating offers a long and proven track record of superior performance. The coating is applied with an electrochemical process, which means that a much smoother and more uniform finish is achieved when you compare the outcome to that of the dip spin coatings. Additionally, the higher alloy alkaline plating is able to maintain consistent performance for long periods of time, even after they have aged due to the methods that are used for their creation.

When you need an item that offers superior corrosion resistance, then looking for zinc nickel alloy plating is going to be a good idea. This will ensure that the item you purchase is able to last long term and that even as it ages, you will not have to worry that it will no longer perform as needed, due to the design and superior function it offers.
