What to Consider before you Electroplate

tin-plating-company

Are you thinking about having parts electroplated?  Here are the most important things you need to take in to consideration before and during the process…

What should you consider Pre Electroplating?

 

  • Nesting

Electroplating involves electrical and chemical reactions on the surface of the part you are wanted to be plated, so exposure is crucial to the result of the final product.  Parts which are nesting will lack adhesion and therefore coverage on the final product.

  • Tolerance

The tolerance on vital dimensions on the part in question should be designated with the plating thickness in mind.  This is should be accounted for when the pieces are ready for assembly after the products have been through the chemical process.

  • Environment and exposure

What is your product going to be exposed to?  A high amount of friction, heat or sea spray?  This is essential for negotiating the thickness of the necessary plating required to maintain the resistance, corrosion and rust protection of the part in question.

  • Geometry

Electroplating involves using a current in order for the reaction to be initiated on the surface of a part, which means that the geometry of the parts surface will influence the distribution of electroplating across the surface.  This is called current density.  It is normal that plating builds up in parts which have sharp corners, bends and threads but it can be prevented if specialists use advanced plating processes.

  • Drainage

The preparation of the surface of a part needing plating must be correct so that the inside surfaces of a part will be sufficiently covered when the process is completed.  This is so that the plating will have the correct bond strength for plating to have been carried out correctly and for the part to have ultimate protection and increase its longevity.  This, for some parts, may mean they need to have a weep hole create during their design phase, so that this can be achieved.

  • Usage

It must be clear what your intended use is for the part you are needing plating.  Make it clear to your specialists what the use and required characteristics are of the part.  Important features include conductivity, low friction, high strength, corrosion resistance, wear, exposure to sea spray or water etc.  This will determine which metal your part is made from (eg. Copper, Nickel, Tin, etc), how your part should be finished and plated.

UK Industrial Output Increased by Rise in Oil and Gas Extraction

 

The UK’s industrial sector has received a significant boost thanks to an increased output of oil, gas and manufacturing. The Yorkshire Post has reported that industrial output grew at its fastest rate in six months in March, after an unexpected bounce in oil and gas extraction.

offshore oilrigOfficial data from the Office for National Statistics has showed that industrial output rose 0.5% in March, after creeping up by only 0.1% in February. This is the strongest growth since September, and has exceeded leading economists’ forecast of that it would remain the same.

Oil and Gas Extraction

Oil and gas extraction rose to 4.9%, which was its fastest rate since February 2014. Falling oil prices and rising production costs as North Sea oil gets scarcer had previously contributed to a general downward trend.

Britain’s economy grew by 2.8% in 2014, the fastest growth rate of any big advanced economy. It did lose pace in the first quarter of 2015 when total output rose by just 0.3%. However, recent data shows that manufacturing output rose by 0.4% after upwardly revised growth of 0.5% in February, which was slightly faster than expected.

Marine Corrosion Protection for the Oil and Gas Industry

Here at NiTEC UK, we carry out a significant amount of metal plating work for parts and components to be used in the oil and gas industries. A common requirement for plated components used in these industries is their ability to resist corrosion for a substantial amount of time, especially in subsea conditions.

Our commitment to research and development allowed us to create SeaTEC100, a metal coating that protects mild steel from salt spray corrosion and marine corrosion for an extensive period of time. SeaTEC 100 has been independently tested to withstand salt spray conditions for over 25,000 hours, a period of time that is unprecedented within the engineering industry.

We provide a range of metal finishing and metal plating services for both onshore and offshore oil and gas applications. For more information about corrosion resistant coatings, please call NiTEC UK on 0845 224 3571 or email info@nitec-enp.co.uk

The Advantages of Corrosion Resistant Coatings

Corrosion and rust can have a catastrophic effect on the safety of a variety of equipment used in the automotive, oil and gas, and engineering industry. And it’s not just the safety of this equipment that’s a problem, corrosion and rust can also affect the reliability and efficiency of the equipment too.

What is Corrosion?

Corrosion occurs when a metal or alloy is attacked by agents in the surrounding atmosphere. This reaction causes the surface of the material to disintegrate into an oxide or sulphide, or even the dissolution of the material into the surrounding environment.

How Do Corrosion Resistant Coatings Work?

There are many things that can degrade metal components, such as exposure to chemicals, oxidation, moisture and salt spray. Corrosion resistant coatings protect the metal from this degradation by providing a barrier between the component and the corrosive material.

The advantages of using components that are resistant to corrosion are numerous.  They can increase the life of a component as they prevent the formation of rust on a part, in turn stopping the part from becoming a catalyst for rust formation on surrounding parts. This, therefore,  prevents part on part rusting and removing the risk of one part affecting the final assembly.

What are the Benefits of Corrosion Resistant Coatings?

Coatings which possess anti-corrosive properties such as electroless nickel plating and diffused nickel plating ensure that metal components have the longest possible life by inhibiting the effect of chemicals, moisture and salt spray etc.

Another benefit of an anti-corrosion coating is that they can tolerate extended periods in extreme conditions such as fluctuations in temperature, exposure to hostile elements and extreme moisture and damp. The use of corrosion resistant plating before the part is exposed to corrosion can reduce costs and delays due to replacement of parts.

Electroless Nickel Corrosion Resistant Coating

electroless nickel plated componentElectroless nickel is a uniform coating that is the perfect solution for critical high-end engineering items used in the defence, healthcare, automotive and aerospace industries.

It is very resistant to corrosion and will therefore extend the life of everything it coats. This makes it ideal for coating parts exposed to harsh environments such as those operating in the marine, oil and gas and defence industries. Therefore, it can reduce the cost of repair and replacement parts.

The process of electroless nickel plating is a great way to prevent corrosion from occurring on parts used in the automotive, oil and gas, and engineering industry. Contact NiTEC today on 0845 2243571 or email web@nitec-enp.co.uk

Nickel Plate Outdoor Metal Sculptures for Corrosion Resistance

As specialists in the electroless nickel plating process, we have previously worked with metal sculptor David Mach, and have nickel plated a few of his pieces. For example, we nickel plated his spaceman and gorilla sculptures which are both made from coat hangers.

nickel plated garden sculptureElectroless nickel can coat metal such as mild steel or stainless steel and make it last for years – that’s why the process of nickel plating is simply perfect for outdoor sculptures. Its corrosion resistance properties and its ability to withstand adverse weather conditions make it the perfect plating solution for metal garden sculptures, and any other sculpture that will be displayed outside.

Large Capacity Electroless Nickel Plating Tanks

The process of electroless nickel plating deposits a uniform coating on to whatever it is plating, and compared to stainless steel, it is also relatively cheap. Our huge nickel plating tanks that are big enough to accommodate very large pieces of sculpture, such as garden sculptures and bespoke pieces such as those plated for David Mach.

The main reason Mach decided on electroless nickel plating to plate his pieces was due to its excellent corrosion resistance and the assurance that gave him that the piece would look stunning for years to come, no matter where it was located. In fact, the corrosion resistance offered by electroless nickel plating is actually better than stainless steel!

A Great Alternative to 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.

The process of electroless nickel plating is a great way to prevent corrosion from occurring on outdoor sculptures made from metal. If you are interested in the process 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.

Decorative Aluminium Bathroom Sink Nickel Plated for Protection

Most people think of the plating activities we carry out at NiTEC as being purely for engineering applications, but as you may have seen from our last few blog posts, we do plate a lot of items for sculptors and artists too. We occasionally receive enquiries to plate more unusual domestic pieces, such as balustrades, staircases, furniture, and this metal basin.

nickel plated basin sink

Aluminium basin nickel plated for corrosion protection

The sink itself was originally cast out of aluminium and featured a large round inset for the basin itself. The bottom of the sink was a rugged texture that looked a lot like the texture of the surface of a jagged rock. As you can see from the picture, it’s a really impressive piece, and will undoubtedly look fantastic in the bathroom of its new home!

Protection for Prolonged Exposure to Water

Due to the amount of running water and handling that the sink would receive when it was used, the aluminium it was cast from was not really appropriate for a sink. Aluminium is very prone to corrosion and can tarnish and discolour easily. Although it doesn’t rust, the surface of the aluminium could become encrusted with calcium and hard water stains, which would leave it looking dull and possibly even stained.

We plated the aluminium sink with an electroless nickel coating to ensure that the surface of the basin remained bright and shiny, and to ensure that the prolonged exposure to water wouldn’t cause any staining or discolouration of the basin. Electroless nickel plating also ensures that the metal coating it deposits grows at a uniform speed all over the part and covers any crevices and rugged areas evenly and thoroughly.

Total Uniform Coverage with Electroless Nickel Plating

The uniform coverage of an electroless nickel coating doesn’t just benefit decorative items such as this sink, it’s also perfect for ensuring uniform coverage for engineering components too. Electroless nickel deposits do not build up on the edges or ends of components, and leave a uniform deposit both inside and out. This means that components can be plated to tight tolerances, meaning that there is no need to machine the part afterwards. This accurate coverage saves both time and money. It’s also a great alternative to stainless steel, too.

If you would like to find out more about the benefits of using electroless nickel plating for corrosion protection and the uniform, even coverage of parts, call the NiTEC team on 0845 224 3571, email info@nitec-enp.co.uk or get in touch via our contact page.

Electroless Nickel Plating for an Oil Rig Vortoil Pipe for Marine Corrosion Resistance

Electroless nickel plating is perfect for applications in the oil and gas industries due to its excellent corrosion resistance properties. When used as a barrier layer, electroless nickel provides the highest levels of corrosion and wear resistance, and the thickness of the coating can be adjusted to suit the application.

Corrosion and wear protection

A recent project of NiTEC’s involved the nickel plating of a vortoil pipe for use on an oil rig. Vortoil pipes are used for separating crude oil from seawater, and are therefore exposed to harsh marine environments and susceptible to corrosion and wear due to their surroundings.

The tolerance of the vortoil pipe had to be less than 3 microns over the length of the component, with an overall deposit thickness of 100 microns.

Electroless nickel is an excellent plating method to ensure uniform levels of thickness over a deposit, but when the competent is a large as a vortoil pipe, there may be slight variations in the thickness of the deposit due to localised changes in temperature and activity.

Because of the size of the component, NiTEC manufactured a jig with a motor which was attached to either end of the pipe. The pipe was then electroless nickel plated horizontally, while it was turned very slowly to make sure all of the surface area was covered by the electroless nickel deposit.

Accurate deposit thickness of the nickel coating

The pipe was approximately 4m in length, and needed to be electroless nickel plated internally and externally, including all the attached pipes, holes and fins. The staff at NiTEC were able to work to the tight distribution tolerances using our monitoring system, which enabled us to ensure the accurate deposit thickness of the nickel coating onto the component.

Why Use Electroless Nickel as an Alternative to Galvanisation?

The process of galvanisation

The process of galvanisation applies a protective coating of zinc onto the metal. This type of coating is commonly used on steel or iron in order to prevent rusting. Galvanisation prevents a ferrous item from rusting, as the corrosion resistance of zinc is much higher than that of steel or iron. Advantages of galvanisation are that it is relatively cheap and easily applied. It also has a very long life and needs little maintenance.

Galvanised componentHot dip galvanisation

Hot dip galvanisation is the most common method of galvanisation. The steel part is submerged in a bath of molten zinc, coating the component with a layer of zinc. Hot-dip galvanisation produces a grey, matte coating to the surface of the metal, which is very thick and durable.

Electroplated galvanisation

Galvanisation can also be achieved using electrochemical and electrodeposition processes. Electroplated coatings are generally less durable and not really appropriate for outdoor applications because the deposit is very thin. This can be helped by painting the surface of the component, which slows down zinc consumption, delays the corrosion and extending its durability.

The advantage of electroplating is that it is much cheaper than hot dip galvanising. It is used for many different outdoor applications but despite looking good when it is new, it isn’t very durable and won’t withstand the elements very well.

An alternative to galvanising

Although galvanisation is cheaper, the final finish isn’t as attractive or durable as some other types of metal finishing. Electroless nickel plating can be used as an alternative to galvanisation as it is durable and aesthetically pleasing.

Electroless nickel plating can also be used in harsh environments because of its high corrosion resistance. The uniform coating created by this process can be a perfect solution for critical high-end engineering items such as those used in the defense, healthcare, automotive and aerospace industries.

Considering the extent of its durability and the attractive finish it creates, electroless nickel plating is cheaper than you might think. It is also the ideal plating for a surface exposed to friction and wear, which can also be increased by using heat treatments.

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.
