FAQs for Electroless Nickel Plating, Shot Blasting & Heat Treatment

 

What is electroless nickel plating?

Electroless nickel plating is the process by which nickel or a nickel alloy is deposited onto a component. It is carried out without the use of an externally applied current, unlike electroplating. The nickel is deposited onto the component from the aqueous solution created by the chemical reaction.

What are the advantages of electroless nickel plating?

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.

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.

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.

Lubricity

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

Solderability and bondability

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

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.

Nonmagnetic properties of high-phosphorus nickel alloy

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

How long will it take for my order to be completed?

As a specialist plating company our capacity and turnaround is fast and efficient. Depending on the size and scale of the order, our standard lead time is 5 days.

Where do NiTEC deliver to?

We frequently deliver throughout the UK, Europe and the world.

Can you provide a quote based on an email?

We are able to provide customers with comprehensive quotes based on drawings and photographs that have been emailed to us. We aim to respond to enquiries within 48 hours.

How hard is electroless nickel plating?

Electroless nickel deposits have hardness values in the range of 450 – 750 VHN, depending on the phosphorus content in the deposit. Generally, the higher the phosphorus content, the lower the as deposited hardness.

Heat treatment can be used to increase the hardness of electroless nickel coatings, achieving in excess of 1000 VHN. This makes the deposit hardness comparable to that of hard chrome, with the advantage of an even coating which will not require post plating machinery.

Salt Spray and Corrosion Resistant Coating

The effects of salt spray on metal coatings can result in corrosion of the surface of the metal. Metal surfaces that are exposed to marine environments need to be fit for use in sub-sea conditions to prevent this type of corrosion from occurring.

Here at NiTEC, we aim to keep at the forefront of our industry by developing products to solve problems such as these. We needed to come up with a product that would be a cost effective answer to extend the life of mild steel exposed to a marine environment.

Components operating in conditions such as these need to last a long time, as the simple act of just replacing them can result in downtime and can be very expensive.

Through years of research, development and testing, we’ve created a product that protects mild steel from salt spray corrosion for an unprecedented amount of hours – SeaTEC 100. It’s a really exciting achievement within the engineering industry, and is ideal for use in sub-sea conditions.

SeaTEC 100 can be used to plate metal components, valves and connectors used in marine environments. It is able to increase the strength of items such as pipeline connectors, which is ideal because these are the points at which the material is at its weakest level.

It has also been tested to withstand salt spray conditions for over 25,000 hours, an unprecedented amount of time within this industry. It is also available in a variety of colours.

SeaTEC100 is an ideal plating for oil rigs and pipes used to transport oil and gas as it can substantially extend the life of materials such as mild steel. This means that downtime as a result of corroded parts is severely reduced or avoided altogether, and the cost of repairing, replacing or maintaining parts is reduced too.

NiTEC also specialise in the process of electroless nickel plating, copper plating, and shot blasting and heat treatment.

Copper Plated Medical Clipboards Kill Bacteria on Contact

As specialists in metal finishing and copper plating, NiTEC endeavour to keep up to date with recent developments in the industry and adapt our services accordingly. Our most recent service is the process of copper plating medical clipboards for use in hospitals.

Copper plating is often used in hospitals and laboratories due to its natural ability to kill bacteria on contact.

NiTEC’s commercial director Marcus Hill believes that copper plating clinician’s clipboards can help to provide an effective defense against the spread of infections such as MRSA in hospitals.

Hospital-acquired infections are not only very common, but they cost the NHS huge amounts of money every year. Research carried out by the University of Southampton has proven that metallic copper surfaces kill microbes in a matter of minutes by causing membrane damage to the bacteria.

Copper has been proven to prevent the horizontal gene transfer in bacteria, which is to blame for antibiotic resistance, in turn increasing the number of health care associated infections. Horizontal gene transfer often takes place in hospitals on surface that are frequently touched. Copper plating therefore contributes to the prevention of infection spread and gene transfer.

Copper plated clip boards are a logical step forward in the quest to reduce the spread of bacteria and provide extra protection alongside the standard hygiene practices in the hospital environment,” said Marcus.
