Increase the Lifespan of Steam Turbines with Electroless Nickel Plating

Based in Derbyshire, Nitec have a wealth of experience electroless nickel plating for large multinational companies and a wide variety of industries.

As a leading provider of worldwide metal plating services, Nitec have recently worked with Elliott Turbo-Steam Turbines. Elliot steam turbines are specially built to be able to perform for years, and they have an excellent reputation as being the best in the industry.

Elliot steam turbines are very reliable and hard wearing, and by adding an electroless nickel coating, their life span can be further increased. As the addition of an electroless nickel coating is very hard, it can reduce the wear of the part when friction is an issue.

Elliot steam turbines are used in power generation and food processing,  chemical and petrochemical, pulp and paper, and the oil and gas industry.

For more information on how electroless nickel coatings can be used to increase the lifespan of components and reduce wear through friction, contact Nitec by visiting our website, or speaking to a member of our specialist team on 0845 224 357.

Electroless Nickel Plating for Rutherford Appleton Laboratories

Rutherford Appleton Laboratories approached Nitec with the prospect of nickel plating a laboratory vacuum chamber. As specialists in the process of electroless nickel plating, the staff at Nitec gladly took on the project.

Thousands of scientists and engineers have used the lab to carry out their research in lots of areas, including astronomy, physics and light sources. With such important research in mind, electroless nickel plating specialists Nitec had to meet all the relevant regulations in order to comply with the high standards requested by Rutherford Laboratories.

The equipment requiring surface treatment was a vacuum chamber, used by the laboratory to carry out tests and experiments  The iron from the chamber walls was a concern for Rutherford Laboratories, as it could affect the results of tests. The lasers which are used in experiments such as these actually had the power to burn through the paint, therefore the chamber needed to be coated with a thin layer of electroless nickel to prevent this happening.

Nitec have a large amount of experience in plating unusually shaped objects and equipment. The expert staff at Nitec had to manufacture tanks to fit each part of the vacuum chamber, as the chamber came in several sections. Some of the parts weighed more than 20 tonnes.

The chamber itself was built like a small room, and had many portals, doors and windows which presented Nitec with the problem of gas traps formed by the recesses. Therefore, the chamber itself, which was originally going to be used as the plating tank and filled with the electroless nickel plating solution, had to be sheeted over and internally shot blasted.

Blanking plates were made for each section of the chamber, and each one was fitted with an air pipe which fed up and outside the chamber in order to remove any excess solution and gas. This process ensured that the vacuum chamber was completely covered by the electroless nickel coating, meeting the high standards of quality required by the laboratory in order for all tests and experiments to be accurate and successful.

To find out more about how Nitec can help your business with their electroless nickel plating needs, even if the object is particularly large or unusually shaped, why not visit our website and take a look at the projects we have embarked upon recently.

Use Electroless Nickel Plating to Replace Hard Chrome

There are many advantages to using electroless nickel plating as an alternative to hard chrome.

Hard chrome is a common choice where the hardness and wear resistance of a component are important. The hardness of hard chrome is in the region of 800 – 1100 VHN.

The hard chrome deposit, however, is applied electrolytically. Metal coatings applied electrolytically generally create an uneven coating which may need post plating machining. The difference in coating uniformity between electrolytic and and electroless nickel plating is illustrated in the image below, and the same theory can be applied to hard chrome applied eloctrolytically and electroless nickel plating. Another disadvantage to hard chrome is that it tends to soften with heating.

Electroless nickel deposits form a perfectly uniform coating, unlike hard chrome. Although electroless nickel does not give the same level of hardness, the process of heat treatment can be used to harden it. Some electroless nickel deposits can be harder than 1000 VHN, making the hardness of electroless nickel plating comparable to that of hard chrome.

As well a electroless nickel plating, NiTEC also specialise in diffused nickel plating finishes, copper plating as a process, shotblasting and heat treatment.

Cheaper Alternatives to Stainless Steel

As specialists in electroless nickel plating, NiTEC are passionate about promoting the advantages of the process over using other metals, such as stainless steel.

Stainless steel is very resistant to corrosion, and can therefore be used when the levels of hardness of the metal are important. But using electroless nickel plating as an alternative to stainless steel has many advantages. Mild steel or cast iron with an electroless nickel coating is a much more cost effective way of achieving high levels of hardness and corrosion resistance.

Stainless steel doesn’t corrode, rust or stain easily with water as ordinary steel would do, but despite its name, stainless steel is not actually fully stain proof.  Stainless steel will in fact stain and even corrode in conditions where there are low levels of oxygen, high levels of salt or poor circulation.

If you are interested in the process of  electroless nickel plating as a cheaper alternative to stainless steel, contact NiTEC on 0845 2243571 or email web@nitec-enp.co.uk and we’ll show you how much you can save.

How Hard is Electroless Nickel Plating?

As a specialist electroless nickel plating company in Chesterfield, Nitec are experts in the plating industry. A question that is frequently asked by customers and potential customers alike is ‘Exactly how hard is electroless nickel plating?

Depending on the phosphorus content in the deposit, electroless nickel deposits have hardness values in the range of 450 – 750 VHN. As a rule, the higher the  phosphorus content, the lower the deposited hardness of the electroless nickel.Mild steel with an electroless nickel coating has properties of hardness and corrosion resistance exceeding the benefits offered by stainless steel.

Increasing hardness of electroless nickel using heat treatment

An effective way of increasing the hardness of the electroless nickel coating is by using the process of heat treatment. Heat treatment can increase the hardness of electroless nickel coatings to in excess of 1000 VHN. This makes the nickel deposit hardness on par with hard chrome, with the added advantage of an even coating which will not require any machinery after plating.

For more information about how we can fulfill your nickel plating requirements, or for advice on using electroless nickel plating an as alternative to stainless steel, please visit the Nitec website, or call our friendly team of staff on 0845 224 357.

Electroless Nickel Plating as an Alternative to Stainless Steel

The electroless nickel plating process is a cost effective solution to coating metals such as mild or stainless steel.

And despite the lower price, electroless nickel coatings still maintain a high level of quality.

Advantages of electroless nickel plating

The metal layer deposited by the electroless nickel plating process has an even thickness over all surfaces of the component, virtually regardless of its shape. 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.

 

How corrosion resistant is electroless nickel?

Electroless nickel is perfect for parts that are regularly exposed to harsh environments such as the marine, oil and gas and defense industries. Nickel plating is very resistant to corrosion and will therefore substantially extend the life of a component. Therefore it can reduce the cost of repair and replacement parts.

How hard is electroless nickel?

When electroless nickel plating is used in association with an appropriate heat treatment, it can be hardened up to 950vhn. Electroless nickel plating is therefore ideal in areas where friction and wear are issues.

The Benefits of Electroless Nickel Plating

The process of electroless nickel plating is ideal for plating engineering components.

Electroless nickel plating creates a uniform coating which prevents corrosion effectively. The deposit formed by electroless nickel plating is based on a chemical reaction, causing the deposit to collect in equal thickness over all the part, regardless of its shape.

This completely uniform coating is a perfect solution for critical high-end engineering items including those used in defense  healthcare, automotive and aerospace.

The uniform coating of the electroless nickel plating also means that the surface is hard wearing, corrosion resistant and durable.

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

Electroless Nickel Plating ‘The Spaceman’: Part 2

As a leading UK nickel plating company, we are often approached by customers with special projects that require expert handling. In the last Nitec blog post, we described our involvement in electroless nickel plating ‘The Spaceman’ for british artist and metal sculptor David Mach.

The size, surface area and fragility of the sculpture were all important considerations that needed to be addressed by the staff at Nitec. The sculpture had been constructed in three parts with an internal support structure.

As specialists in the process of electroless nickel plating, we are used to handling and plating large engineering components. An oversized nickel plating tank was used to nickel plate the sculpture, and the internal support structure of the piece was used for jigging.

By using this method, the fragile exterior of the sculpture was protected and it was subjected to the minimal amount of handling by Nitec staff.

 

When the sculpture had been through the process of nickel plating, a thin lacquer was applied to the surface and then and baked on in the furnace. This process helped to maintain the appearance of the electroless nickel coating while the statue was on show.

To find out more about electroless nickel plating and the way it can be used in art and sculpture, or for more information about our specialist nickel plating services, please visit the Nitec website.
