Electroless Nickel Plating a Large Manifold for the Mining Industry

NiTEC are a UK based company providing worldwide metal plating services and specialising in electroless nickel plating.

We were approached by Joy Mining Macinery to manufacture a component, a piece of pipework that needed plating to prevent it from corrosion and wear. Joy Mining Machinery is a global leader in the development, manufacture, distribution and service of underground mining machinery for the extraction of coal and other bedded materials. Therefore, NiTEC’s high standards of quality electroless nickel plating and fast turn-around times were vital to the success of the project.

The component itself was approximately 1.5m square, by 1m deep. It appeared to be a solid block of steel, with two small holes in opposing corners on one face. The block also contained an intricate network of pipes, which would be used to carry water as a coolant. Joy Mining needed this pipework plating to ensure corrosion prevention, which the process of electroless nickel plating can provide to the highest standards.

To plate the component, flexible pipes were connected to the holes in the block. The electroless nickel plating solution was then pumped from a holding tank through the block, and back to the holding tank, on a continuous basis.

As electroless nickel has to be at 90°C to operate, the block was immersed in a tank of cleaning solution, maintained at 70-80°C to prevent heat loss and flash rusting of the exterior of the block. The plating solution was analysed and maintained throughout the process and any necessary additions were subsequently made to the holding tank.

Electroless Nickel Plating for Engineering

There are many advantages of using electroless nickel plating for engineering purposes.

Even coating

Electroless nickel plating provides an even coating of nickel across the surface of the component. This is useful in engineering applications because it allows the nickel coating to be built up in order to increase the size of the item, and improve dimensional conformance.

Thickness

Electroless nickel coatings are also good for engineering purposes because the thickness of a nickel coating can easily be adjusted.

This means that no matter the specification, the thickness of the electroless nickel plating can be adjusted accordingly.

Blind holes and recesses within the metal can also be plated effectively using electroless nickel plating, as it plates wherever the nickel touches the item.

Corrosion resistance

Electroless nickel plating not only offers good cohesion and excellent performance, it is also very resistant to corrosion and wear.

Nickel plating as a barrier layer

Nickel plating can be used to plate uniformly over all surfaces, and can be used for applications where brightness is not required. As a barrier layer, nickel is plated on oil field valves, drive shafts, electrical tools and industrial machinery.
