A beginner’s guide to electroless nickel plating

Electroless nickel plating is a process which deposits an even alloy coating to a range of materials.

There are different types of ENP

There are several different types of ENP, which are suited to different materials and parts. Broadly the process remains the same and involves immersing parts into a solution containing nickel salts and further details can be found on the websites of specialists such as //www.poeton.co.uk/surface-treatments/plating/electroless-nickel-plating.

ENP delivers high quality outcomes

While traditional electroplating often produces inconsistent results with edge build-up and poor coverage on more complex parts, ENP is a much more reliable option with a range of different applications.

ENP offers excellent durability

Traditional electroplating provides some durability to parts, however an electroless nickel coating consistently offers better corrosion resistance, wear resistance, and hardness. For this reason, engineers often choose ENP for the most intricate and challenging parts.

ENP is compatible with a variety of materials

A range of different materials are suitable for ENP, including steel, copper and aluminium. The key to achieving a high quality finish is to give each material the appropriate pre-treatment, which will ensure a strong bond, optimal durability, and longevity. There is also interesting research happening into enhancing the outcomes of ENP at low temperatures, which may offer even more versatility.

ENP is cost-effective

ENP is more cost-effective over the longer term when compared to traditional plating. This is because ENP is more durable and has better corrosion resistance, which means that parts won’t need to be replaced as often and maintenance downtime can be minimised.
