Common Applications of Electroless Nickel Coatings

Electroless nickel plating can be applied to a variety of components. Its fantastic properties make it the perfect plating solution for a variety of applications, including the following:

Electroless nickel hard driveElectrical equipment

Electroless nickel coatings are perfect for electrical equipment due to their solderability and conductivity properties.

Applications include heat sinks, computer drive mechanisms, memory disks and drums, terminals and lead wires, chassis, connectors, diode and transistor cans, interlocks, junction fittings and printed circuit boards.

Packaging and handling machinery

Packaging and handling machinery can benefit from an electroless nickel coating due to its properties of wear resistance, cleanliness and the attractive finish it provides.

Chemical equipment

Nickel coatings have excellent chemical resistance, making them perfect for applications in the chemical and petroleum industries. This includes ball, gate and plug valves, chokes and control valves, oil field tools, oil well tubing and pumps, drilling mud pumps and blowout preventors.

Molds and dies

Electroless nickel coatings are used for molds and dies due to the lubricity of nickel that minimises erosion and abrasion. This coating is commonly used on zinc die cast dies, glass molds, plastic injection molds, and plastic extrusion dies.

Food service equipment

Electroless nickel is commonly used to plate food service equipment due to its superior corrosion and wear resistance, its an attractive finish and high degree of cleanliness.

Salvage

Electroless nickel coatings can be used for restoring parts to their original dimensions, for example, molds, shafts, landing gear and gears. They can also be used to repair mis-matched parts as they are a cost effective alternative to hard chrome and often eliminate subsequent machining or grinding operations.

The Advantages of Electroless Deposition of Nickel

electroless nickel deposit on componentsElectroless solutions have the advantage of producing coatings which have a very high degree of uniformity. This means that electroless nickel is ideal for plating complex shapes and can be used effectively to salvage parts that have been mis-machined. It also allows worn components to be recycled.

Electroless nickel deposits vs electrolytically-applied coatings

Electroless nickel deposits are chemically applied using an autocatalytic immersion process which does not use an electrical current.

This is much different from electroplating, which depends on an external source of direct electrical current to produce a deposit on the substrate material. Because the electrical current cannot be evenly distributed throughout the component itself, it is hard to obtain a uniform deposit with electrolytically-applied coatings.

Electroless nickel is often chosen above electrolytically applied coatings because of its ability to coat irregularly shaped, highly detailed parts with complex geometries. The completely uniform deposit thickness is perfect for achieving close dimensional tolerance capabilities.

15 Reasons To Choose Electroless Nickel for your Metal Plating Needs

electroless nickel plated componentWhen considering a plating method, there are lots of options you can consider. Here at NiTEC, we are experts in electroless nickel plating and consider the process superior to many other coatings on the market.

There are many advantages to electroless nickel plating that in our opinion make it a cut above the rest.

For example, electroless nickel:

  • Allows the deposit to coat a variety of surfaces, many of which would be difficult if not impossible to plate using the process of electroplating.
  • Is a very cost effective solution to coating metals such as mild or stainless steel.
  • Can substantially extend the life of a component.
  • Produces a metal layer with a very even thickness over all surfaces of the component, regardless of its shape or dimensions. This means that there is little or no excess deposit at high points on the component.
  • Deposits of electroless nickel have excellent physical and chemical properties, including hardness, wear resistance and lubricity.
  • Creates a uniform coating that makes it ideal for critical high-end engineering items, especially those used in the defense, automotive, healthcare and aerospace industries.
  • Has a high level of corrosion resistance making it perfect for extending the life of anything that it coats. This makes it the perfect solution for parts that are exposed to harsh environments such as the marine, oil, gas and defense industries.
  • Because of its ability to extend the life of components due to its high levels of corrosion resistance, electroless nickel coatings can reduce the cost of repair and replacement parts.
  • Prevents the formation of rust on a component, therefore preventing the parts around it from rusting too.
  • Tight manufacturing tolerances can be achieved with an electroless nickel coating because of its ability to deposit nickel evenly on the surface of a component
  • Can be used to improve the surface of a component so that it is back within the specified tolerances.
  • Provides the surface of the component with a surface layer that allows post finishes to be carried out effectively.
  • Has self lubricating properties which reduce the wear of a component through friction, creating minimal coating weight loss.
  • The use of electroless nickel on a component creates a coating that will not flake or chip off like some paints and lacquers will.
  • Can be hardened up to 950vhn with the appropriate heat treatment.

Nickel PTFE Coatings Prevent Seizure in Pistons

Piston ringWhat is a piston?

A piston is a component of a reciprocating engine, and is comprised of a disk or cylindrical part that slides to and fro in a hollow cylinder.

In an internal-combustion engine the piston is forced to move by the expanding gases in the cylinder head, and is attached by a pivoted connecting rod to a crankshaft or flywheel.

These components therefore convert the reciprocating motion into rotation.

Electroless nickel PTFE coatings on pistons

Nickel PTFE combines the lubricity of polytetrafluoroethylene with the hardness and corrosion resistance of electroless nickel.

Electroless nickel PTFE coatings are perfect for use on pistons due to its properties of low friction wear and self lubrication. This type of coating also increases the life of the component because of its wear resistance and high levels of corrosion protection.

Nickel PTFE coatings also provides long life dry lubrication which prevents sticking and galling on the component, making it perfect for improving the efficiency of pistons.

Coating a piston with electroless nickel PTFE will reduce the friction and wear on the surface of the component, and reduce the operating temperature of the part. An electroless nickel PTFE coating can also do the following:

  • Increase horse power and torque
  • Reduce or eliminate detonation
  • Allow higher compression ratios to be utilised
  • Allow tighter piston to wall clearances for a better ring seal

If you are looking for a metal coating that will extend the life and efficiency of pistons, Nickel PTFE is the perfect solution. Call us on 0845 224 3571, email us at info@nitec-enp.co.uk or visit the contact page on our website to make an enquiry.

Electroless Nickel – Corrosion and Wear Protection

The corrosion protection provided by electroless nickel plating can extend the life of a component. This is due to its ability to block the formation of rust on a component, which in turn stops it from becoming a catalyst for part on part rusting. This has massive advantages in all industries because it is not necessary to worry about one bad part contaminating the rest, or it jeopardizing the final assembly of the product.

Electroless nickel also improves the quality of components because it allows for tight manufacturing tolerances. This is because electroless nickel creates a uniform build-up of nickel on all surfaces, regardless of their shape and dimensions. It can also be used to build parts that may have been out of specification back into tolerance. By using an electroless nickel coating on worn parts, they will be reusable in the capacity of post machining and other post finishes.

electroless nickel plated componentsThe advanced properties of corrosion protection that electroless nickel can offer means that components can be manufactured from a less expensive metal and coated using nickel. By not having to make the part out of a more expensive metal, profit margins can therefore be increased.

The wear protection provided by electroless nickel can also extend the life of a component. An electroless nickel coating will reduce wear of a part due its self lubricating properties and high levels of hardness.

This means that there is minimal weight loss on the coating from part on part friction. Electroless nickel also provides outstanding release properties and anti stick surfaces.

Electroless nickel coatings won’t chip off, flake, peel or rub off like some paint or lacquer type top coats which have been applied without pre-surface treatments. So there’s also no need to worry about the strength of the coating.

If you are looking for a metal coating that has outstanding levels of wear and corrosion resistance, electroless nickel is the perfect solution. Call us on 0845 224 3571, email us at info@nitec-enp.co.uk or visit the contact page on our website to make an enquiry.
