3 Reasons to Choose Electroless Nickel Plating Over Galvanisation

What is Galvanisation?

When a metal is galvanised, a protective zinc coating is applied to it. This zinc coating is applied to steel or iron in order to prevent the surface of the metal from rusting. Hot-dip galvanisation is the most common method of galvanisation. During this process, the steel parts are submerged in a bath of molten zinc. This process is also achievable through electrochemical and electro deposition processes but there are some differences between them.

Electroless Nickel as an Alternative to Galvanisation

Electroless nickel plating and galvanisation are both effective metal finishing techniques for the prevention of corrosion and rust on the surface of metal. If you’re trying to decide which would be a better coating for your application, here are 3 reasons why you should choose electroless nickel plating as an alternative to galvanisation.

  1. Durability and Corrosion Resistance

The electroless nickel plating process is a high quality, cost effective solution to coating metals such as mild or stainless steel and can substantially extend the life of a component. It is an excellent alternative to galvanisation as it is both durable and aesthetically pleasing.

  1. Uniform Coating

Not only does electroless nickel plating provide enough corrosion resistance to be used in harsh environments, the uniform coating it creates can be a perfect solution for critical high-end engineering items such as those used in the defence, healthcare, automotive and aerospace industries.

  1. Cost Effectivity

Electroless nickel plating is also much cheaper than you would imagine, considering the extent of its durability, and the wear resistance of the surface can be increased by using heat treatments. This makes it an ideal specialist plating where friction and wear may be problematic with regard to the use of the component.

Electroless Nickel Plating Vs Galvanisation

Electroless nickel plating and galvanisation are both effective metal finishing techniques for the prevention of corrosion and rust on the surface of metal. If you’re trying to decide which would be a better coating for your application, we’ve put together a bit of information comparing the processes so that you can make an informed decision.

Protecting Metal Using Galvanisation

When a metal is galvanised, a protective zinc coating is applied to it. This zinc coating is applied to steel or iron in order to prevent the surface of the metal from rusting. Galvanisation is an effective way of preventing the ferrous item from rusting, as the corrosion resistance of zinc is much higher than iron or steel. It is also a cheap process, easily applied and has a long, maintenance free service life.

Hot-dip galvanisation produces a grey, matte coating to the surface of the metal, which is very thick and durable. Electroplated coatings are less durable and unsuitable for outdoor applications because of the thinness of the deposit. This can be overcome to some extent, however, by painting the surface which slows down zinc consumption, therefore delaying the corrosion and extending its durability.

Why Use Electroless Nickel as an Alternative to Galvanisation?

The process of galvanisation

The process of galvanisation applies a protective coating of zinc onto the metal. This type of coating is commonly used on steel or iron in order to prevent rusting. Galvanisation prevents a ferrous item from rusting, as the corrosion resistance of zinc is much higher than that of steel or iron. Advantages of galvanisation are that it is relatively cheap and easily applied. It also has a very long life and needs little maintenance.

Galvanised componentHot dip galvanisation

Hot dip galvanisation is the most common method of galvanisation. The steel part is submerged in a bath of molten zinc, coating the component with a layer of zinc. Hot-dip galvanisation produces a grey, matte coating to the surface of the metal, which is very thick and durable.

Electroplated galvanisation

Galvanisation can also be achieved using electrochemical and electrodeposition processes. Electroplated coatings are generally less durable and not really appropriate for outdoor applications because the deposit is very thin. This can be helped by painting the surface of the component, which slows down zinc consumption, delays the corrosion and extending its durability.

The advantage of electroplating is that it is much cheaper than hot dip galvanising. It is used for many different outdoor applications but despite looking good when it is new, it isn’t very durable and won’t withstand the elements very well.

An alternative to galvanising

Although galvanisation is cheaper, the final finish isn’t as attractive or durable as some other types of metal finishing. Electroless nickel plating can be used as an alternative to galvanisation as it is durable and aesthetically pleasing.

Electroless nickel plating can also be used in harsh environments because of its high corrosion resistance. The uniform coating created by this process can be a perfect solution for critical high-end engineering items such as those used in the defense, healthcare, automotive and aerospace industries.

Considering the extent of its durability and the attractive finish it creates, electroless nickel plating is cheaper than you might think. It is also the ideal plating for a surface exposed to friction and wear, which can also be increased by using heat treatments.
