Long Lasting Components with Increased Performance

The process of electroplating is very cheap and very popular. But many customers come to realise that nickel electroplating, chrome electroplating and stainless steel do not last as long as they had hoped. Their original goal with electroplating or using stainless steel may have been to reduce costs and ensure that the part stayed in good condition for the entirety of its life, but sadly this is not always the case.

Electroless nickel plated componentThe importance of plating components

Plating components is really important to ensure their longevity because it provides a barrier between the component and the atmospheric working conditions. If plating isn’t applied to end products, corrosion and wear will cause the functionality of the part to deteriorate very early on its life.

This often has a knock on effect to the unit it was assembled into as well, causing it to be much less effective and eventually unusable. But keeping your parts from failing doesn’t have to mean that you have to settle for expensive metal alloys, stainless steel, or an electroplated finish. You can use electroless nickel plating instead.

Why should I choose electroless nickel plating instead of electroplating or stainless steel?

The electroless nickel plating service from NiTEC UK is of an exceptionally high quality and meets the required engineering specifications. This means that you will have the peace of mind that your plated components will last indefinitely, effectively protected from corrosion and wear for years to come.

African Well Sponsored by NiTEC Up and Running

NiTEC sponsor water wellWe are pleased to announce that our water well has been built in is in full working order out in Africa!

Last year we sponsored a well for AquAid, the company who supply the NiTEC offices with water coolers.

We recently received confirmation that our well has been built and is up and running making a real difference to people’s lives.

We are very proud to be associated with such an amazing project, and delighted to be able to make such a difference in the lives of those less fortunate.

Aquaid and the Africa Trust

Aquaid raises funds to build fresh drinking water wells in areas of Africa where it is needed the most, such as schools and villages. And for every water bottle that we get from Aquaid for the NiTEC offices, a donation is made to the The Africa Trust.

Also, we recently put a badge of support on our website, to let people know about this great cause, and show our commitment to helping Aquaid’s recent project installing the elephant pumps in parts of Africa.

“I’m absolutely delighted that we can help to support such a worthwhile and needy cause,” said NiTEC Commercial Director Marcus Hill. “It’s fantastic to be involved in supporting AquAid and The Africa Trust, everyone at NiTEC is thrilled to be involved and doing their bit to help.”

Clean, Strengthen and Polish Metal with Chilled Iron Shot-Blasting

shot blasting services

What is shotblasting used for?

Shotblasting is a method which is used to clean, strengthen or polish metal.

This method is used in a variety of industries, including aerospace, automotive, construction, shipbuilding and foundry. Basically, it can be used in any industry that uses metal!

Airblasting

Airblasting is a form of shotblasting that is carried out using a blastroom or blast cabinet. The blast media, for example iron, is pneumatically accelerated by compressed air and projected by nozzles onto the compartment.

The shotblasting media itself can be mixed with water, which is called wet blasting. In wet blasting and air blasting, the nozzles can be installed in fixed positions or they can be operated manually. They can also be operated using an automatic nozzle manipulators or even robots.

Shotblasting facilities at NiTEC

At NiTEC we pride ourselves on using the most technically advanced equipment to achieve the highest quality finish on all our projects. Our shotblasting capabilities include the following.

  • The ability to shot blast components of up to 20 tonnes in weight.
  • The capacity to shot-blast up to a 216m³ components.

If a finer surface finish is required then it is also possible to blast the component with Aluminium Oxide 180-220 grit.

The shot blast booth at NiTEC, used for shotblasting and heat treatment, has a capacity of 216m3 and is made from stainless steel which minimises the particles that settle on the work. We also pride ourselves on our excellent customer service, our fast turnaround times, quality workmanship and competitive rates.

Common Applications of Electroless Nickel Plating

nickel-coating-for-aerospace-industry

Electroless nickel coatings can be used in a wide variety of common applications. The superior corrosion resistance, hardness levels and wear resistance make it a very versatile coating.

Aerospace

Electroless nickel coatings have the perfect properties for use in the aerospace industry, for example, they can be used in the protection of hydraulic control systems.

Nickel coatings can also be used for the refurbishment and the recovery of worn machined parts. They can also be used to correct incorrectly machined parts enabling the component to be used.

Electrical and Electronics

Nickel coatings are used for electrical and electronic applications due to their ability to protect the components successfully. For example, electroless nickel coatings may be used for electrical connectors and hard drive computer components in order to impart corrosion protection and wear resistance. They are also useful for providing solderability and a non-porous barrier layer, and to otherwise enhance the performance or useful life of a particular component.

Automotive

The automotive industry has specified electroless nickel plating on brake, transmission and steering assembly components, in addition to other parts. Electroless components enhance performance, and with longer lasting parts, they can help automakers to extend their product warranties.

The energy industry

Electroless nickel coatings can be used for chemical and wear resistance to equipment in the oil and gas industry. It is also useful for coalfield cutting tools, as it provides a wear resistant coating that doesn’t carry the risk of sparking.

General engineering

Electroless nickel plating can be used in a wide variety of applications within general engineering. For example, it can be used for wear resistance in plastics and textile handling equipment, corrosion resistance in chemical handling plants, appearance, and wear resistance in automotive applications.

Corrosion and Chemical Resistant Coatings

Here at NiTEC, we spend our days electroless nickel plating components for a variety of applications including aerospace, electrical/electronics, the energy industry, and general engineering.

Properties of electroless nickel coatings

Hardness

Electroless nickel coatings produce very tough, abrasion and corrosion resistant surfaces, which can be further hardened with heat treatment. The hardness of the plated surface can also be increased by decreasing the phosphorus content of the coating, usually to around 2%.

Corrosion resistance

They also have a good natural corrosion and chemical resistance. These properties can also be maximised by increasing the phosphorus content of the coating, usually to 10% or above.

Electroless nickel and phosphorous levels

The chemistry of electroless nickel plating solutions can be altered to give the plated coating different properties, for example, a medium phosphorus coating, a low phosphorous coating and a high phosphorus coating.

Medium Phosphorous electroless nickel coating

Electroless nickel coatings with medium phosphorous content are the most commonly used and applied electroless nickel coatings. They generally have a phosphorous content of 6-9% and a VPN of roughly 500. However, this can be increased further with heat treatment. The coating tends to be bright, with a normal plating thickness range of 3-50 microns. Medium phosphorous electroless nickel coatings are very stable and reliable with fast plating rates.

Low phosphorous electroless nickel coating

Low phosphorous electroless nickel coatings contain less than 3% phosphorous and are very hard. With the appropriate heat treatment, a low phosphorus coating can be in the region of 1000 Vpn. The normal plating thickness of this type of coating is in the region of 10-25 microns and is grey/silver in colour.

High phosphorous electroless nickel coating

Electroless nickel coatings with high phosphorous contents typically have very high levels of corrosion and chemical resistance. High phosphorous coatings are non-magnetic, silver/grey in colour and have a normal thickness range of 25-75 microns. Plating rates are typically slow and the plating solution tends to have a short life.
