7 Great Reasons to Choose Electroless Nickel Plating

Here at NiTEC, we know that no other metal coating has the fantastic combination of properties offered by electroless nickel. Here are 7 great reasons to choose electroless nickel plating!


1. Corrosion resistance and corrosion protection

One of the most common reasons for the use of electroless nickel coatings in functional applications is its excellent corrosion resistance. In the very corrosive conditions encountered in drilling and producing oil wells, for example, electroless nickel has the ability to withstand the combination of corrosive chemicals and abrasion.

2. Wear resistance

With the appropriate heat treatment, electroless nickel plating can be hardened up to 950vhn. This makes it ideal for areas exposed to friction and wear.

3. Hardness

A great feature of electroless nickel plating is its hardness. Hardness values for electroless nickel deposits are in the range of 450-750 VHN, depending on the phosphorous content of the deposit.

4. Lubricity

Electroless nickel plating has natural self lubricating properties, which eliminates the need for liquid lubricants on components.

5. Solderability and bondability

Electroless nickel-phosphorus alloys are easily soldered with a highly active acid flux.

6. Uniformity of deposit regardless of geometries

Electroless nickel plating has a completely uniform coating. It’s a perfect solution for critical high-end engineering items including defence, healthcare, automotive and aerospace. Electroless nickel can be deposited to produce a wide range of coating thicknesses, with uniformity and minimum variation from point to point.

This uniformity can be maintained in plating both large and small parts and on components that are fairly complex, with recessed areas. Electroplating of such parts, on the other hand, would produce thickness variation and possible voids in the plating when coating holes and inside diameters.

7. Nonmagnetic properties of high-phosphorus nickel alloy

Electroless nickel deposits containing greater than 8 percent phosphorus are considered to be essentially nonmagnetic as plated.

Eliminate Post-Plate Grinding with Electroless Nickel Plating

An electroless nickel coating can eliminate the need for post-plate grinding because of its ability to deposit a reliable, uniform coating.

The metal layer deposited by the electroless nickel plating process has an even thickness over all surfaces of the component, virtually regardless of their shape. As the components are not deformed by the plating process, the uniformity of the coating obtained by the nickel plating makes the process ideal for engineering components. Therefore, this uniform coating is the perfect solution for critical high-end engineering items such as those used in the defense, healthcare, automotive and aerospace industries.

The deposition of a uniform electroless nickel coating save time, effort, and money because no processing of the part is needed after plating. Therefore, tight manufacturing tolerances can be achieved with an electroless nickel coating as it is deposited evenly on the surface of the part.

The uniform coating of the nickel plating means that the surface is very hard wearing, resistant to corrosion and durable in a variety of environments.

 

The deposition process of electroless nickel is autocatalytic, meaning that once a primary layer of nickel has formed on the substrate, that layer and each subsequent layer becomes the catalyst that causes the above reaction to continue. Thus, very thick coatings can be applied, provided that the ingredients in the plating bath are replenished.

NiTEC are also specialists in diffused nickel plating technology, the copper plating process and the process of shotblasting & heat treatment. For more information about nickel plating services in the UK, take a look at our website, or call us on 0845 224 3571.

Electroless Nickel Plating ‘The Spaceman’: Part 2

As a leading UK nickel plating company, we are often approached by customers with special projects that require expert handling. In the last Nitec blog post, we described our involvement in electroless nickel plating ‘The Spaceman’ for british artist and metal sculptor David Mach.

The size, surface area and fragility of the sculpture were all important considerations that needed to be addressed by the staff at Nitec. The sculpture had been constructed in three parts with an internal support structure.

As specialists in the process of electroless nickel plating, we are used to handling and plating large engineering components. An oversized nickel plating tank was used to nickel plate the sculpture, and the internal support structure of the piece was used for jigging.

By using this method, the fragile exterior of the sculpture was protected and it was subjected to the minimal amount of handling by Nitec staff.

 

When the sculpture had been through the process of nickel plating, a thin lacquer was applied to the surface and then and baked on in the furnace. This process helped to maintain the appearance of the electroless nickel coating while the statue was on show.
