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.

Quality Electroless Nickel Plating

As specialists in electroless nickel plating, it is of the upmost importance that the quality of our work is of the highest standard.

We pride ourselves on working closely with customers to achieve the required quality. We believe that there should always be a discussion between the staff at NiTEC and the end user in order to set the optimum process parameters to achieve the specific plating needs.

The electroless nickel plating process is guaranteed to be carried out faultlessly with the help of a quality monitoring system.

The pre-treatment, electroless nickel process parameters, and the plated deposit can all be controlled to ensure the electroless nickel  process is perfect.

Quality depends on a number of different factors, including:

-The Substrate

-Pre – treatment

-Type of electroless nickel process

-Plating parameters

-Thickness

-Post Treatment

The Properties of Nickel Deposit

The deposit properties of an electroless nickel layer, and subsequently the performance of the plated component depend upon the following:

-The phosphorous content

-The purity

-The substrate

-The pre-treatment

-The thickness

The structure of nickel phosphorous deposits is either micro crystalline or amorphous, which is a form of metallic glass. Nickel phosphorous deposits are homogenous and generally pore free.

Electroless nickel deposits possess excellent chemical resistance and corrosion protection properties. Electroless nickel deposits are resistant against most organic and inorganic chemicals apart from oxidising acids. The chemical resistance is especially good in neutral and alkaline solutions and a protective layer of electroless nickel on steel or aluminiuim can provide years of lasting protection against even aggressive industrial and marine conditions. The thickness of the deposit depends on the specific corrosive conditions and there are recommendations for each.

Mechanical properties of electroless nickel deposits

Electroless nickel deposits can be plated with tensile or compressive stress. Depending on the type of deposit, the ductility is between 0.1 and 2%. The micro hardness of electroless nickel deposit layers is between 500 to 700 Vickers Pyramid Number.

Electroless nickel layers can also be co-deposited with different inclusions for many applications. This is used particularly to give improved abrasion resistance. Electroless nickel can be co-deposited with silicon carbide, PTFE or even diamond.

Electroless nickel deposits may also be heat treated to temperatures above 240 degrees centigrade. This process can improve abrasion resistance and increase hardness. It can also enhance adhesion. To achieve maximum levels of hardness, parts are required to be treated at a temperature of 400 degrees centigrade for one hour. It is possible to enhance the abrasive wear resistance of electroless nickel deposits by using heat treatment in this way. The average coefficient of friction is about 0.3 and can be much smaller in certain cases, even as low as 0.03.

Types of Metal Finishing

Electroplating 

Electroplating occurs when an electric current is passed through a solution which contains the metal object and it acts as a cathode. Aluminum, cadmium, bronze, brass, copper, gold, chromium, lead, iron, platinum, nickel, tin, silver and zinc can all be used for plating ferrous and non-ferrous objects.

Electroless Plating

During electroless plating no electric current is passed. The chemical is deposited on the metal product causing a chemical reaction. Salt (source metal), complexing agent, reducer, various buffers and other chemicals are used to complete the process. Copper and nickel are commonly used in printed circuit boards.

Immersion Plating

Immersion plating is very similar to electroless plating, but unlike electroless plating which uses a mixture of two chemicals, immersion plating creates the metal plating reaction through the metal substrate. This process displaces the chemical, producing a thin metal deposit on the product. Immersion plating is proven to create more waste than electroplating and electroless plating.

Other methods of metal finishing include cladding, case hardening, galvanized coatings, electro-polishing and metallic coatings.

Shotblasting and Heat Treatment

To ensure the very best quality nickel plating, it’s very important that the surface is prepared properly. The best way to do this is through shotblasting and heat treatment solutions.

As nickel plating specialists, NiTEC have the capacity to shotblast components up to 20 tonnes in weight. To ensure a high standard of surface finish, we use Aluminium Oxide 180-220 grit for the heat treatment process. As well as this, we also offer chemical cleaning and activation processes.

The shot blast booth used for shotblasting and heat treatment has a capacity of 216m3 and is made from 316 stainless steel. These features help to minimise the levels of particles which settle on the work.

NiTEC’s heat treatment facility

The furnace in our heat treatment facility has a temperature range of 0-700 °C. NiTEC has two furnaces, furnace 1 is 1.5m x 1.5m x 2m high, and furnace 2 is 1.7m x 1.7m x 2.2m high.

Shotblasting solutions

We can create heat treatment profiles for many different requirements with our chart recording equipment that monitors the temperature changes of the furnace and the work. This means that we can be sure that the material gets up to the required temperature for exactly the right amount of time. Therefore, we eliminate the possibility of heat sinks on large components or mixed loads.

Heat treatment solutions

Heat treatment solutions can be used for stress relieving and de-embrittlement as pre-plate and post-plate treatments. Small components can be loaded onto shelves to maximise the heat treatment capacity, and minimise the cost of the treatment for the company.

NiTEC are also able to diffuse the electroless nickel layer into the steel using high temperature heat treatment solutions for sustained periods. This process doesn’t affect the increased corrosion protection that this type of deposit offers, making it ideal for the offshore oil industry and perfect for marine environments. It also has the benefit of giving the coating a degree of flexibility.

We do also offer electroless nickel plating as an option, the process of diffused nickel plating and bright copper plating.

Benefits of Electroless Nickel Plating: Uniform Coating

The deposit formed by Electroless nickel plating is based on a chemical reaction. Therefore, the deposit collects in equal thickness over all the part, regardless of its shape.  

The alternative, electrolytic plating, relies on an electrical current passing from an anode to the component, the cathode, which is then subject to changes in current density, applicable to its shape. These variations in current density result in variations in deposit thickness.

Therefore, the metal surface finishing process of electroless nickel plating is a more suitable choice for engineering components as it provides the surface with a uniform coating.

Benefits of a uniform coating 

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.

Electroless nickel deposits are excellent for corrosion prevention. With regard to the corrosion protection mechanism, the nickel deposit exhibits electro-negative or ‘noble’ behaviour. Therefore, the nickel plating process relies on total encapsulation of the substrate to be effective.

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. Due to the nature of the chemical reaction, the deposit that forms is an alloy of nickel and phosphorus.

NiTEC are also specialists in diffused nickel plating technology, the copper plating process and the process of shotblasting & heat treatment.
