Rising Base Metals Rocketing to the Top?

nickel-plating-plated-nitecBase metals are essential in the growth of the infrastructure, manufacturing and utilities sector of the UK.  The mining of base metals refers to major industrial non-ferrous metals like nickel, copper, tin and aluminium.  It is the dramatically increasing energy and urbanisation demand which are making the need for the metals rise, as well as the fact that they are used for automotive systems, metal coatings, electrical systems and make many goods more durable.  But will fluctuating prices negatively impact the base metal market?

 

Nickel Plating is Key

In 2014, Lead-zinc accounted for 24% of the global market and copper accounted for 16%.  Zinc was popular due to its specific characteristics, such as its unique bonding abilities with other metals, anti-corrosive properties and it has the ability to galvanise well.  The attributes have boosted its use considerably.  Copper is predicted to rise, forecast until 2023, thanks to its proven strength in the infrastructure sector.  The use of tin is also set to rise through the use of tin coating for electronic components in the automotive sector.  However, the most interesting sales increase seems to be a very specific area of the Nickel world to increase its sales – this seems to be nickel plating – though the reasons or sectors remain unspecified.

 

Information Regarding Nickel Plating

There are two types of Nickel Plating – Electroless Nickel Plating (ENP) and Diffused Nickel Plating.

Diffused Nickel Plating is a simple process which is the most effective nickel coating, ensuring a high resistance level against corrosion.  This is thanks to its total encapsulation plating method.  It has been proven that their corrosion resistance is more effective than that of the highest grade stainless steel, whilst at the same time being much cheaper.  Diffused Nickel Plating is the perfect plating method if your components are used in marine or salt environments.  This gives them a 30 year sub-sea guarantee.

In a similar way, Electroless Nickel Plating is a high quality but cost effective solution to metal coating which can extend the longevity of components dramatically.  It is creates a good resistance against corrosion and is often used in marine, oil and defence industries.    Electroless Nickel Plating prevents rust, wear and friction.  It can also be hardened through the use of heat treatment and is guaranteed not to chip or flake, like paint or varnish does.

Electroless Nickel Plating and Diffused Nickel Plating

A question often asked is…What is the different between the two types of Nickel Plating?  The basic answer is very simple – the plating processes used are very different.

It has already been deciphered that Diffused Nickel Plating occurs when the encapsulation plating method is performed but this is not the same as Electroless Nickel Plating.  The process for this occurs when a layer of even thickness metal is deposited evenly over the surface of a component, no matter what its shape.  The uniformity in its coating means that it is the perform plating method for components which are used in particular industries, such as Healthcare, Defence, Automotive and Aerospace, where the components are often not standard, need to be hygienic, regularly cleaned and are under constant stress.

Plating to Perfection

metal plating company OscarThey were first designed in 1928.  They are made in Chicago.  They are plated in copper, nickel and silver before being coated in 24-carat gold.  What are we talking about?  An Oscar!

These 14 inch, 8.5 pound statuettes are the literally the definition of perfection in more ways than one.  If they are not perfect, then the makers are lead to starting the statuettes from scratch, time and time again.  But once they are deemed perfect, they are guaranteed for life!  The iconic Art Deco Academy Award takes a long 10 days to repeat from start to finish, partly because there is only one Oscar mould and also because so many processes take place in their production, such as electroplating.

About the Oscar

It was designed by Cedric Gibbons, the MGM art director, who sketched the subjected standing on a film reel with five spokes.  These five spokes represent the original five branches of the Academy and was originally called the Academy Award of Merit.  Each Oscar is engraved with a serial number and now over 3,000 Oscars have been awarded.  These Oscars may begin their lives in Chicago but one classified as ‘perfect’ are packaged and flown, with guards, to Los Angeles for the award ceremony.  An interesting fact about Oscars is that although they are guaranteed for life, if they are damaged, an actor can send them back and have them either replaced or restored to their former glory.  They are meant to be priceless objects and there is an act to say that they are not resalable.  However, this electroplated objects of splendour have continued to be traded in the shadows with some of the highest sales exceeding $250,000 and Michael Jackson paid $1.5million for a Best Picture award for Gone With The Wind 1939 in 1999.

The Gold Plated Apple

Apple watch for gold plating

Apple watches which have been gold plated tend to cost a minimum of $10,000 if you buy directly from Apple, for the 18 carat gold edition.  So instead there is now the option to purchase a DIY kit for $100 which also entails a step by step guide to this cheap solution to gold plating yourself with 24 carat gold.  This is a much more cost effective option than sending your Apple watch back to Apple to do it for you which costs at least $400.  There are also other benefits from the DIY set – for example, you can touch up gold plated areas once they begin to fade or show signs or wear and this can be done at your convenience, too.

The 3 P’s – Plating, Process and Products

After only a couple of decades, the metal finishing world has been transformedElectroplating is the most modern form of metal finishing which is used in a wide array of industries such as aerospace, automotive, healthcare and military defence, to name but a few.  During this electrochemical process the metal ions in solution are bonded to a metal substrate via the process of electrodeposition.

Pre-Electroplatingletter-p

Before electroplating was a front runner in the metal finishing world, parts had to be properly cleaned before entering a series of chemical baths to prepare and activate in order to prepare and activate the metal to create strong adhesion created during the process of electrodeposition.

The Plating Process

Electroplating baths involve multiple variables and components which must be closely monitored constantly.  The parts have a constant power supply provided directly to them which initiates the ion attraction in the solution towards to metallic surface.  Every time a mole of electrons is transferred to the part in question, one mole of metallic ions in solution adhere directly to the part as well.  Whilst this happens a chemical reaction also occurs on the surface of the part which includes ions being reduced and oxidised.

What do you need to consider before electing to use Electroplating?

  • Because electrical and chemical reactions are both involved in the electroplating process, exposure is critical to the finished product. The nesting of parts will create a lack of adhesion and lack of coverage which should be avoided.
  • Plating thickness should be kept in mind when dimension tolerance is designated and the extra room for electroplating should be left so that parts fit together after the process has occurred.
  • What environment are the parts going to be exposed to? This will help you to decide what level of thickness you will require in order for your part to be made corrosion proof.
  • The geometry of the part in relation to the current distribution aka current density, across the surface of a part. Plating builds up on sharp corners, bends and threads for example.
  • Do you need to think about the drainage of plating solutions the addition of a weep hole may need to be added during its design phase in order for it to be successful.
  • Think about the type of metal you should be using in relating to the job you want it to do for you! What characteristics do you need the surface to have for the job in question?  Does it need to be a conductor, have low friction, be strong, corrosion resistant, hard wearing etc?  This should make you therefore lead you in to thinking about the types of plating which would be effective – Gold plating, Silver plating, Nickel plating or Copper plating

To Be Or Not To Be? That Is The Automotive Question

Before you decide what coating you need to enhance the surface of any metal, you should first think about your operating environment and the impact the coating in question could have, what it could be and what it definitely should not be.

Specialised coatings are used to:

  • Enhance metal surfaces permanentlyMINIandClassicMini
  • Solve wear
  • Prevent corrosion
  • Increase lubrication
  • Decrease release problems

The Automotive Industry

In this industry, surface coating usage has grown hugely over the last fifty years.  It was then that the internal combustion engine was usually manufactured out of cast iron, forged steel and die-cast aluminium alloysHeat treatment was combined with white metal or bronze bearings in order to provide wear surfaces.  These were lubricated by the oil films pumped through large expanses created between moving surfaces. Though they operate in the same way, cars and their engines today must last greater distances, adhere to emissions regulation and aim for  reduced consumption of fuel in order for lighter engines, lower engine tolerance and lower friction between moving parts.  This has meant that a wider array of coatings has become necessary to overcome certain common problems, such as wear, corrosion and friction and aid the long-life performance that our modern cars need.

Automotives Bare All

  • Piston crowns are often coated with thermal insulated ceramic coatings, usually in diesel engines.
  • Mating cylinder linings can be coated with electrolytic or electroless plated composite finishes Silicon carbide, diamond or boron nitride.
  • Fuel storage and delivery systems need electroless nickel plating (especially in bio fuel consuming cars), frequently enhanced by powder coatings or e-coat top coats.
  • Brakes require hard anodising, enhanced by applying paint or powder coating top coats.
  • Brake systems, fluid delivery pipework and air suspension systems use ductile zinc nickel plating.
  • Motors contain neodymium, iron, boron magnets which need TriCem coating and heat treatment, to enhance magnetic performance but to leave the alloys unaffected.

The Composition and Structure of Electroless Nickel Plating

Component plated with high phosphorus electroless nickelThe structure of electroless nickel is responsible for the unique properties it possesses, making it such a useful metal coating. Electrodeposited nickel typically has a crystalline structure, whereas an electroless nickel deposit is normally described as having an amorphous structure or one consisting of ultra-fine crystallites. The amorphous nature of electroless nickel deposits become more dominant as the phosphorus content increases, and phosphorus contents above 10.5% are typically considered truly amorphous.

The absence of a well-defined crystal structure eliminates the possibility of inter-granular corrosion that can be a problem with crystalline deposits, such as electrolytic nickel. Electroless nickel, therefore, provides a barrier that is more effective at protecting a substrate from corrosion.

Heat Treatment and Electroless Nickel Plating

Heat treatment can also be used to change the properties and structure of nickel phosphorus deposits. High temperature heat treatment solutions for sustained periods can be used to diffuse the electroless nickel layer into the steel, giving a degree of flexibility to the coating. This process does not affect the increased corrosion protection offered by this type of deposit.

The Composition of Electroless Nickel Coatings

The phosphorus content of an electroless nickel coating has a great effect on the properties of the deposit, and can be varied over a wide range.

High Phosphorus Electroless Nickel Coatings

For example, high phosphorus electroless nickel typically contains a phosphorus content of between 10-12%, making it ideal for applications where a uniform, hard and highly corrosion resistant coating is required. Other advantages include low porosity, pit-free deposits and a very stable and robust coating.

Medium Phosphorus Electroless Nickel Coatings

Medium phosphorus solutions contain between 6 and 10% phosphorus and produce a coating which effectively combines intermediate hardness with good corrosion resistance. Medium phosphorus coatings deposit rapidly and produce a bright or semi-bright coating.

Low Phosphorus Electroless Nickel Coatings

A low phosphorus electroless nickel coating typically contains 2.5% phosphorus. This produces a very uniform porous free coating which uniformly covers the complete surface of the component, including inside recesses. It has excellent corrosion resistance in alkaline conditions, but the coating is relatively soft, below 235VPN, and is therefore not particularly wear resistant.

7 Advantages of Electroless Nickel Coatings

For engineers looking to protect parts from wear, friction and corrosion, electroless nickel plating offers a range of advantages.

1. Effective Barrier Coating

Electroless nickel coatings are often less porous than electroplated nickel and hard chrome, providing an effective barrier of corrosion protection to steel. It can also be applied with none or little compressive stress, therefore making it gentle in application.

electroless nickel plating company uk2. Hardness

Electroless nickel coatings can reach up to 1000 VHN with the appropriate heat treatment and provide an excellent hard coating for light metals.

3. Wear Resistance

This type of coating has excellent wear resistance properties, and can, therefore, extend the life of a part or component. As parts can be used for longer, plating components with electroless nickel means that money can be saved on repairs and replacements, and the impact on the environment can be reduced.

4. Uniform Deposit

The process of electroless nickel plating provides flexibility of thickness and volume of the plating on metal surfaces. It can also be used to easily fill recesses or pits in the metal surface, resulting in a uniform deposit and surface finish. This means that a wide variety of industrial parts can be plated, including oil field valves, pumps, drive shafts, electrical and mechanical tools, and engineering equipment etc. The uniformity of electroless nickel coatings also means that close tolerances can be adhered to.

5. Natural Lubricity

Electroless nickel plating has natural lubricity, and has excellent release and anti-galling properties.

6. No Electricity Needed

Electroless nickel plating does not need any electricity; therefore the process can be completed in a more controlled environment with less equipment than traditional electroplating.

7. Cost Effective

Electroless nickel plating is a much more cost effective way of plating metal, requiring fewer coats to produce a strong, high quality coating. Also, the reduction in equipment and time needed for the process in comparison to electroplating makes it an efficient, cost effective process. Electroless nickel plated mild steel is also an excellent replacement for more expensive materials.

Top 5 Properties of Electroless Nickel

As experts in the process of nickel plating, the NiTEC staff are highly experienced and knowledgeable regarding the use of this innovative plating technique. There are many benefits to using nickel plating over other metal finishing techniques, many of which are outlined below.

nickel plating technical figure

1. Uniformity of Coating

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 the defence, healthcare, automotive and aerospace industries.

2. Ultimate Corrosion Resistance

Electroless nickel coatings are often used in functional applications because of the excellent corrosion resistance it provides. Nickel coatings are able to withstand the combination of abrasion and corrosive chemicals, even in the very corrosive conditions encountered in drilling and producing oil wells.

3. Wear Resistance

Electroless nickel has excellent levels of wear resistance. As a barrier layer, it is used on oil field valves, drive shafts, electrical tools and industrial machinery. The life of any metal exposed to harsh environments can be extended using this type of plating, therefore reducing the cost of repair and replacement parts. It basically extends the life of everything it coats! And with the appropriate heat treatment, electroless nickel can be hardened up to 950vhn, which makes it ideal for areas exposed to friction and wear.

4. Excellent Adhesion

A high level of adhesion can be achieved on a wide range of substrates, including steel, copper, and aluminium. The typical bond strengths reported for electroless nickel on copper and iron alloys range from 50 to 60,000 psi. The bond strength on light metals such as aluminium tends to be lower, somewhere in the range of 15 to 35,000 psi.

Heat treatment at a low temperature is commonly used to improve the adhesion of electroless nickel on all metals, especially on light metals such as aluminium or titanium. During this heat treatment, diffusion occurs between the atoms of the coating and the substrate.

The surface preparation and activation of the electroless nickel plating is one of the most important factors for producing excellent adhesion.

5. Cost Effectiveness

Specialist electroless nickel plating is much cheaper than you would imagine. NiTEC now have 7 dedicated nickel plating lines and can offer reasonable quotations based on drawings or photos sent to us.

As you can see from the points made above, electroless nickel plating has many huge benefits that make it the plating method of choice for many industries. Call NiTEC on 0845 224 3571, email us at info@nitec-enp.co.uk or visit the contact page on our website to make an enquiry.

The Advantages of Electroless Deposition of Nickel

electroless nickel deposit on componentsElectroless solutions have the advantage of producing coatings which have a very high degree of uniformity. This means that electroless nickel is ideal for plating complex shapes and can be used effectively to salvage parts that have been mis-machined. It also allows worn components to be recycled.

Electroless nickel deposits vs electrolytically-applied coatings

Electroless nickel deposits are chemically applied using an autocatalytic immersion process which does not use an electrical current.

This is much different from electroplating, which depends on an external source of direct electrical current to produce a deposit on the substrate material. Because the electrical current cannot be evenly distributed throughout the component itself, it is hard to obtain a uniform deposit with electrolytically-applied coatings.

Electroless nickel is often chosen above electrolytically applied coatings because of its ability to coat irregularly shaped, highly detailed parts with complex geometries. The completely uniform deposit thickness is perfect for achieving close dimensional tolerance capabilities.

If you would like to find out more about using electroless plating as an alternative to electroplating, call us on 0845 224 3571, email us at info@nitec-enp.co.uk or visit the contact page on our website to make an enquiry.

Electroless Nickel – Corrosion and Wear Protection

The corrosion protection provided by electroless nickel plating can extend the life of a component. This is due to its ability to block the formation of rust on a component, which in turn stops it from becoming a catalyst for part on part rusting. This has massive advantages in all industries because it is not necessary to worry about one bad part contaminating the rest, or it jeopardizing the final assembly of the product.

Electroless nickel also improves the quality of components because it allows for tight manufacturing tolerances. This is because electroless nickel creates a uniform build-up of nickel on all surfaces, regardless of their shape and dimensions. It can also be used to build parts that may have been out of specification back into tolerance. By using an electroless nickel coating on worn parts, they will be reusable in the capacity of post machining and other post finishes.

electroless nickel plated componentsThe advanced properties of corrosion protection that electroless nickel can offer means that components can be manufactured from a less expensive metal and coated using nickel. By not having to make the part out of a more expensive metal, profit margins can therefore be increased.

The wear protection provided by electroless nickel can also extend the life of a component. An electroless nickel coating will reduce wear of a part due its self lubricating properties and high levels of hardness.

This means that there is minimal weight loss on the coating from part on part friction. Electroless nickel also provides outstanding release properties and anti stick surfaces.

Electroless nickel coatings won’t chip off, flake, peel or rub off like some paint or lacquer type top coats which have been applied without pre-surface treatments. So there’s also no need to worry about the strength of the coating.

If you are looking for a metal coating that has outstanding levels of wear and corrosion resistance, electroless nickel is the perfect solution. Call us on 0845 224 3571, email us at info@nitec-enp.co.uk or visit the contact page on our website to make an enquiry.

 

High Phosphorus Electroless Nickel Coatings

High phosphorus electroless nickel provides the highest levels of corrosion resistance. It is often used in industries that require high levels of resistance to strongly acidic corrosive environments, for example, coal mining and oil drilling.

Component plated with high phosphorus electroless nickelElectroless nickel containing high levels of phosphorus has a low degree of solderability, and will only be solderable for a limited time after plating. This makes it perfect for electronic parts such as connector housings and semiconductor packaging.

The microhardness levels of high phosphorus electroless nickel coatings range up about 600 VPN. This type of nickel coating makes for low levels of surface porosity, and is not prone to staining.

Also, when the phosphorus content is greater than 11.2%, deposits are non-magnetic.

Features of high phosphorus electroless nickel:

  • Corrosion resistant
  • Fast deposition rate throughout life
  • Consistent deposition rate throughout life
  • Very stable and robust

If you are looking for a metal coating that provides high levels of corrosion resistance, high phosphorus electroless nickel is a great solution. Call the NiTEC team on 0845 224 3571, email info@nitec-enp.co.uk or get in touch via our contact page.

Features of Electroless Nickel PTFE Coatings

Nickel-PTFE combines the engineering properties of nickel with the lubricity of polytetrafluoroethylene.

Just like standard electroless nickel, the Nickel PTFE deposit occurs as a result of an autocatalytic chemical reaction which allows a reliable, repeatable coating of uniform thickness. This coating makes it possible to coat parts with sharp edges, seams, threads, deep recesses and complex shapes.

During the plating process, the PTFE particles become embedded throughout the deposit of nickel. The unique composite of Nickel PTFE allows for renewed polytetrafluoroethylene at the surface of the component, even as the coating wears. The chemical process involved in the production of Ni-PTFE coatings means that the PTFE is uniformly dispersed throughout the nickel deposit in order to ensure optimum performance in high friction and non-lubricated applications.

Features of Nickel PTFE Coatings

  • Long life lubrication
  • Dry lubrication, reducing sticking and galling
  • Good mold release, eliminating spray releases
  • Hydrophobic
  • Uniform coverage, particularly good for complex shapes
  • Can be heat treated for increased hardness
  • Good for hign friction applications
  • Natural lubricity eliminating the need for standard lubrication
  • Moving parts such as slides and bearings work with improved efficiency and quieter operation

If you are looking for a nickel coating that combines the lubricity of polytetrafluoroethylene with the hardness and corrosion resistance of electroless nickel, NiTEC can help. Call us on 0845 224 3571, email us at info@nitec-enp.co.uk or visit the contact page on our website to make an enquiry.

How Are Nickel Coatings Used in Aircraft?

Nickel coatings are often used on various parts of aircraft due to its fantastic properties of corrosion resistance and hardness. Needless to say, the Aircraft industry has an ongoing need for nickel plating.

Electroless nickel plating is used in the Aircraft industry to provide:

  • Corrosion resistance at high temperatures to protect airfoil components from erosion and abrasion.
  • Provides a coating that will allow high nickel/chromium alloy parts to be joined by brazing or welding.
  • To repair worn or damaged components so that they can continue to be used rather than scrapped.

Electroless nickel coatings have been used on the following aircraft parts:

  • Bearing journals
  • Servo valves
  • Compressor blades
  • Turbine blades
  • Pistons
  • Engine shafts
  • Engine mounts
  • Landing gear
  • Hydraulic and manifold systems
  • Gyroscope components and optics
