Advantages of a High Phosphorous Electroless Nickel Alloy

An electroless nickel coating is a dense alloy of nickel and phosphorus. The amount of phosphorus co-deposited can range from less than 2% to more than 12%, depending upon bath formulation, operating pH and bath age.

High phosphorous electroless nickel plating tanksAn electroless nickel coating with a high phosphorous content is extremely effective in the oil, gas and coal industry. These environments are highly corrosive and therefore require a phosphorous content of more than 10%.

Phosphorous content in electroless nickel deposits can vary from 1 – >12% by weight and the variation can be controlled to result in a number of deposit types.

High Phosphorus Deposits

  • Typically contain 10-12% phosphorus
  • Very high corrosion resistance
  • Complete lack of magnetic response.
  • Most conditions in the highly corrosive oil, gas and coal industry require deposits with a high phosphorus content (>10%).

Low Phosphorus Deposits

  • Typically contain 2-5% phosphorus.
  • Improved hardness and wear characteristics
  •  Higher temperature resistance
  •  Increased corrosion resistance in alkaline environments.
  • Best suited to the chloro-alkali industry, such as the transportation of liquid soda.
  • Enhanced solderability and bondability, especially in electronic applications.

Mid Phosphorus Deposits

  • Typically contain 6-9% phosphorus
  • Bright and aesthetically pleasing
  • Good hardness and wear resistance
  • Moderate corrosion resistance

Alkaline nickel-phosphorus

  • Plate at a relatively low temperatures (75-140°F, 24-60°C)
  • Suitable for plating on plastics and other nonconductive materials
  • Suitable for use on zincated aluminum.

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: Perfect for Replacing Stainless Steel

Electroless nickel plating is an excellent alternative to stainless steel. Stainless steel can be very expensive, especially when making large components. Making large parts out of cast iron and then electroless nickel plating them afterwards is a much cheaper and quicker solution.

Stainless steel can be used in environments where corrosion resistance is important and where the levels of hardness of the metal are also important. However, despite its name, stainless steel is not actually fully stain proof.

Unlike ordinary steel, it doesn’t corrode, rust or stain easily with water. But under certain conditions, for example, where there are low levels of oxygen, high levels of salt or poor circulation, stainless steel will stain and in some circumstances will even corrode.

Electroless nickel plate: alternative to stainless steel

Mild steel that has been electroless nickel plated can actually be more effective than stainless steel. With regards to levels of hardness and corrosion resistance, an electroless nickel coating can exceed the benefits offered by stainless steel. Stainless steel is a lot more expensive than mild steel or cast iron that has been electroless nickel plated.

It is far more cost effective to electroless nickel plate parts made of mild steel or cast iron for the ultimate levels of corrosion resistance. Electroless nickel is not only a more cost effective solution, it is also a much more efficient solution to the problems of corrosion, wear and hardness.

As leading specialists in the electroless nickel plating field, we have the facilities to electroless nickel plate large components as an alternative to stainless steel. The equipment and methods used at NiTEC mean that even the most difficult large part can be plated correctly and consistently.

For more information about replacing stainless steel with electroless nickel plating to increase corrosion resistance of the component and keep costs down, visit the NiTEC website, or call our friendly team of staff on 0845 224 3571.

Derbyshire Based Chilled Iron Shot Blasting Service

Here at NiTEC, electroless nickel plating specialists based in Chesterfield, Derbyshire, we also offer the service of shot blasting using chilled iron grit.

Using chilled iron grit for shot blasting is the perfect way to remove contamination from a metal surface as it can be used to remove paint, to remove sand from castings, and to provide a sound key for painting. It can also be used to remove scale and treat a surface after heat treatment.The shot blasting services available at NiTEC are carried out on site according to our policy statements, industry standards and best practices in the field.

Chilled iron grit is used for shot blasting because its angular abrasive particles make it ideal for removing paint and oxides from ferrous castings and carbon steels. This cleaning process is fairly aggressive, making it only suitable for harder metals.

Chilled Iron Shot-Blasting Services in Derby, Nottingham, Chesterfield and Sheffield

Chilled iron shot blasting is a great way to clean various types of metal as it effectively removes paint adhesive, plastic and rubber insets, grease and rust. This process then leaves the component ready to be restored.

 

Here at NiTEC, we commonly use chilled iron shot blasting to repair and restore car parts, garden furniture, steel window frames and any other metal component that has suffered corrosion and wear over time.

Nickel Plating for the Packaging Industry

As specialists in the electroless nickel plating process, NiTEC have recently had an influx of orders for electroless nickel plating grooved rolls used in the packaging industry.

We are able to plate objects of up to 20 tonnes in weight, and are the only company in Europe with the capacity to plate such large components.

The grooved rolls are typically used in packaging, can weigh up to 5 tonnes and measure 12 metres in length. As packaging material passes over the rolls at speeds of 1200 metres a minute, these huge components have particularly tight tolerances.

Commercial Director of NiTEC UK, Marcus Hill, said: “Grooved rolls are enormous pieces of equipment. We are the only electroless nickel plating company in Europe to be able to handle such a large component, so naturally we see a number coming through our doors.”

Electroless nickel is the only type of plating suitable for this purpose because it provides a uniform coating, is very corrosion resistant and resilient to wear.  Manufactured using mild steel, the grooved rolls are coated with 30-50 microns of electroless nickel. They typically spin at very high speeds and therefore need to be perfectly balanced.

“With other surface treatments, the part would need to be plated and balanced afterwards,” says Marcus Hill. “But with electroless nickel, we are able to balance the grooved rolls, and then plate them, which is far more convenient for everyone.”

If you would like more information about NiTEC’s capacity to plate large objects, please visit our website, contact our friendly team on 0845 224 3571, or email us at info@nitec-enp.co.uk.

6 Things You Need to Know about Electroless Nickel Plating

What is electroless nickel?

Electroless nickel is an alloy of nickel and phosphorous.

How does electroless nickel plating work?

Electroless nickel plating occurs when an auto-catalytic reaction deposits a coating of nickel onto a substrate.

Unlike electroplating, it doesn’t require an electric current passing through the solution to form a deposit, hence the term ‘electroless’.

What are the advantages of an electroless nickel coating?

An electroless nickel coating provides great corrosion protection, even in the most extreme environments. It is very hard and has excellent wear resistance. Another fantastic feature of electroless nickel plating is that it can be used where close tolerances are required for components, meaning that there is no need for grinding after plating.

What surfaces can electroless nickel plate be applied to?

Electroless nickel can be used to plate most base materials including stainless steel, steel, copper and brass.

Why use electroless nickel plating over other plating methods?

Electroless nickel plating can be used to plate very complex shapes with a uniform coating. Unlike electrolplating, the deposit has a completely uniform thickness all over the component in question. The electroless nickel plates all parts of the components surface, regardless of holes, recesses, or sharp angles.

In which industries is electroless nickel plating used?

Electroless nickel plating is perfect for use in offshore applications. It has been used in a wide variety of other engineering disciplines including automotive, defence, aerospace and electronics.

If you have more questions about electroless nickel plating or would like to find out more about it’s suitability regarding your project, visit the Nitec website, or call and speak to a member of our staff on +44 (0) 845 224 3571

Metal Pickling at NiTEC

Among our other services including electroless nickel plating; we also offer the option of metal pickling.

Pickling can be used to effectively remove impurities from a metal surface such as stains, rust or scale. This type of metal surface treatment uses strong acids to remove impurities from the surface of the metal and is commonly used to clean or descale steel.

We have recently been involved with a project pickling stainless steel for the Aerospace group Meggitt. The components, which were to be used in a project in offshore Brazil, were pickled using hydrofluoric and nitric acid.

These types of acid are effective in removing discoloured scale from stainless steel.

 

Many processes that occur at a high temperature can leave a discolouring oxide residue or scale on the surface of the metal. Pickling the component removes the scale from the surface of the metal, leaving it looking much cleaner and brighter.

Acids are difficult to handle because they are so corrosive. Therefore, pickling is a process that requires the upmost care and safety. Luckily, we have the experience and expertise to carry out this process safely.

If you would like more information about Nitec’s experience working with substances such as hydrofluoric acid, please don’t hesitate to call us on 0845 224 3571 or email us at web@nitec-enp.co.uk. Alternatively, you can visit the Nitec website for more information.
