6 Things You Need to Know about Electroless Nickel Plating

What is electroless nickel?

Electroless nickel is an alloy of nickel and phosphorous.

How does electroless nickel plating work?

Electroless nickel plating occurs when an auto-catalytic reaction deposits a coating of nickel onto a substrate.

Unlike electroplating, it doesn’t require an electric current passing through the solution to form a deposit, hence the term ‘electroless’.

What are the advantages of an electroless nickel coating?

An electroless nickel coating provides great corrosion protection, even in the most extreme environments. It is very hard and has excellent wear resistance. Another fantastic feature of electroless nickel plating is that it can be used where close tolerances are required for components, meaning that there is no need for grinding after plating.

What surfaces can electroless nickel plate be applied to?

Electroless nickel can be used to plate most base materials including stainless steel, steel, copper and brass.

Why use electroless nickel plating over other plating methods?

Electroless nickel plating can be used to plate very complex shapes with a uniform coating. Unlike electrolplating, the deposit has a completely uniform thickness all over the component in question. The electroless nickel plates all parts of the components surface, regardless of holes, recesses, or sharp angles.

In which industries is electroless nickel plating used?

Electroless nickel plating is perfect for use in offshore applications. It has been used in a wide variety of other engineering disciplines including automotive, defence, aerospace and electronics.
