5 Great Properties of Electroless Nickel Plating

No other metal coating has the combination of properties offered by electroless nickel, which is why so many industries use the coating and reap the benefits of it. As specialists in electroless nickel plating, NiTEC know that the properties of nickel plating are incredibly useful to our clients, enabling parts coated to have the highest levels of corrosion protection and hardness. Here are the top 5 great properties of electroless nickel, and why they are so important.

Uniform Thickness

The metal layer deposited by the electroless nickel plating process has an even thickness over all surfaces of the component, virtually regardless of its shape. This uniform coating is the perfect solution for critical high-end engineering items such as those used in the defence, healthcare, automotive and aerospace industries.

Electroless nickel can be deposited to produce a wide range of coating thicknesses. Even when plating large and small parts and on components that are fairly complex with recessed areas, the uniformity can be can still be maintained. The range of thicknesses for electroless nickel in commercial applications is 0.1 to 5 mils, although it is possible to create deposits as thick as 40 mils.

Corrosion Resistance

Electroless nickel coatings are often used in functional applications because of its excellent corrosion resistance. Electroless nickel coatings are able to withstand the combination of abrasion and corrosive chemicals, even in the very corrosive conditions encountered in drilling and producing oil wells.

Adhesion

Excellent adhesion of electroless nickel deposits can be achieved on a wide range of substrates, including steel, aluminium, copper and copper alloys. Heat treatment at a low temperature is commonly used to improve the adhesion of electroless nickel on all metals, especially on light metals such as aluminium or titanium. During this heat treatment, diffusion can occur between the atoms of the coating and the substrate. The surface preparation and activation of the electroless nickel plating is one of the most important factors for producing excellent adhesion.

Tight Manufacturing Tolerances

Tight manufacturing tolerances can be achieved as the electroless nickel is deposited evenly on the surface of the part. It can be also used to improve the surface of a component so that it is back within the specified tolerances, and provides a surface that allows post finishes to be carried out effectively.

Chip Free Coating

When using electroless nickel to plate a component, the coating provided is guaranteed not to chip or flake like other top coats such as paints or lacquers.

Common Applications of Electroless Nickel Coatings

Here at NiTEC UK, we have an impressive total of 7 nickel plating lines, making us one of the largest nickel plating providers in Europe. As experts in the process of electroless nickel plating, we’ve put an article together describing the common applications of this unique metal plating service, illustrating its versatility and wide reaching advantages.

Aerospace Components

Electroless nickel plating is commonly used for aerospace components due to its excellent wear resistance, corrosion protection, chemical resistivity and lubricity. These fantastic qualities are perfect for use on valves, pistons, engine shafts, engine mounts, compressor blades and other flight-critical components.

Oil & Gas Components

Nickel plating is used primarily for corrosion protection in the oil and gas industry. It is incredibly effective at protecting parts used in harsh undersea and underground environments, for example on parts such as valves, pumps, and pipe fittings.

Automotive Components

Electroless nickel plating is commonly used for the purpose of wear protection and corrosion resistance on components such as pistons, cylinders, gears, differential pinon ball shafts, fuel injectors, ball studs, transmission thrust washers, knuckle pins, hose couplings, heat sinks and others.

Food Service Equipment

With its superior corrosion and wear resistance, attractive finish and cleanliness, electroless nickel coatings are perfect for food service equipment.

Electrical Equipment

Electroless nickel is often used for electrical equipment due to its solderability and conductivity properties.

Packaging and Handling Machinery

Electroless nickel is commonly used to plate components used in the packaging and handling machinery due to wear resistance, cleanliness and attractive finish.

Chemical Manufacturing and Transport Equipment

The chemical resistance of electroless nickel coatings makes them ideal for chemical manufacturing and transport equipment.

Molds and Dies

Electroless nickel coatings provide corrosion protection on molds and dies, and also help to minimise erosion and abrasion. Also, their low coefficient of friction improves release.

Plastics Manufacturing Equipment

Nickel plating is a common choice of plating of plastics manufacturing equipment due to its durability and release properties on injection molds and extrusion dies.

Printing Industry Equipment

It is often used for plating components and equipment used in the printing industry due to its excellent abrasion resistance on conveyance and chemical resistance on printer cylinders.

Salvage

Electroless nickel plating is commonly used to salvage old parts. It naturally deposits a very even layer of electroless nickel, therefore is often used to restore parts to their original dimensions, or bring mis-machined parts into tolerance.
