ABCD – Aluminium, Boron, Coating, Diamonds

Over the last decade, the demand for aluminium moulds has increased dramatically but consistently and apparently this shows no sign of slowing down, changing or ceasing all together.  Metal coatings are provided for a range of fabricated metal components, but the largest business currently is mould coating and plating.  Specifically the demand for aluminium itself is increasing.  This is because companies have begun to discover that that aluminium moulds can last longer, much longer, than what they were predicted.  The extra longevity of the aluminium moulds can be enhanced further if buyers opt for the mould to be plated with electroless nickel.  This is a cost effective way to extend the life of aluminium tooling and has become extremely popular with automotive suppliers.  Alternatives to aluminium coating or plating can be nickel boron plating and nickel diamond plating which are also popular but aluminium remains the optimum and is only set to continue growing in demand.

Nickel Boron Plating

Nickel boron is a surface deposit coating that can be applied to many different metals including stainless steel, aluminium and titanium.  It acts as a great alternative to chrome plating and has many benefits, which include extending wear and corrosion resistance.  The nodular structure of nickel boron reduces drag in aerodynamic and fluids in circumstances such as ship propellers, down-hole oil crude oil pumping equipment, automotive and truck transmissions and greaseless guns.

Nickel Diamond Plating

Nickel Diamond Plating is where electroless nickel deposits are combined with particles of diamonds.  Many substrates can be coated using this method such as carbon, aluminium, stainless steel and alloys.  Substrates, once coated in this, become extremely highly corrosion and wear resistant and therefore have a much increased lifespan.  Part maintenance and replacement costs are reduced dramatically, as are the costs for such.  This is a popular technique in industries such as textile industry, wood working tools, computer parts, paper handling equipment, automotive water pumps, chemical process pumps and gage blocks.nickel-diamond-plating-nitec

Choose the Right Coating to Maximise Product Optimisation in the Automotive World

The idea of a specialised coating is for the surface of metals to be permanently enhanced by them.  This can be used on other substrates as well and on many components and equipment, too.  These specialised coatings, in effect, act as a deterrent and solve wear, corrosion, lubricant and release problems.   But to choose the best coating for you, the most important things which must be taken in to consideration is the operating environment.

Put a Coat on!

Surface coating usage has grown enormously in the automotive industry over the last fifty years.  Initially, the internal combustion engine was usually manufactured from cast iron, forged steels and die-cast aluminium alloysHeat treatment provided the wear surface for these elements along with white metal or bronze bearings.  They were oiled and lubricated to allowance clearance between moving surfaces.  Half a century later, this method is still used today, though we need and expect more out of our cars.  We expect them to last longer, drive considerably more substantial distances and we need them to abide by our emissions regulations now, too – no mean feat!  In case that wasn’t enough, we expect our cars to do all of this with less fuel and lighter engines which have a lower tolerance to engineering and lower friction between their moving parts.  Due to this, a wider range of materials and coating variety have been required by us all, so that the wear, corrosion and friction problems and expectations could be overcome.

Automotive Parts and Protective Coatings

Piston rings, skirts and pins are coated frequently by hard-wearing, low friction coatings.  This is to hengine-block-nitecelp the initial running-in and advocates long-life performance.  It also helps with lower oil lubrication levels which are commonly associated with cold engine starts and reduces the amount of lubricant allowed to enter the combustion chamber.  Ceramic coatings provide the thermal insulation of piston crowns, usually in diesel engines, where increased and high temperature thermal spray or vacuum use methods are often practiced.

Mating cylinder linings can be coated with electrolytic or electroless plated composite finished which incorporate hard particles of silicon carbide, diamond or boron nitride.  The engines design and performance influence are what enable the design engineer to make the coating choice.

Bio fuels have caused a large amount of corrosive issues with the fuel input systems, fuel storage and fuel delivery systems.  There are a great array of thin coatings which can be applied to these areas in order to prevent corrosion from occurring such as electroless nickel plating which is often enhanced with the use of powder coating or e-coat top coats.

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

Nickel Plating: The Perfect Metal Coating to Protect Brake Calipers from Corrosion and Wear

nickel plated brake caliperBrake calipers are one of the most important parts of the breaking system of a car. They are a necessity in the process that allows your car to stop, therefore it is essential for them to be hardwearing and long lasting. As vital parts of a car’s breaking system, calipers squeeze the brake pads against the surface of the brake rotor in order to slow or stop the vehicle.

How do Brake Calipers Work?

In a disc-braking system the car’s wheels are attached to metal discs, or rotors, that spin along with the wheels. The brake caliper’s job is to slow down the wheels of the car by creating friction with the rotors. The brake caliper itself fits over the rotor like a clamp, and inside it is a pair of metal plates which have been bonded with friction material called brake pads.

Corrosion and Wear Protection

Nickel plated coatings are excellent at protecting steel from corrosion and wear. Electroless nickel plating is used in a variety of applications to extend the life of components, therefore, it is the perfect metal plating technique for brake calipers. Brake calipers are also exposed to a variety of difficult environments, for example heat, cold, summer, winter, snow and salt. Therefore, a corrosion resistant coating on brake calipers is very important to ensure the longevity of the cars braking system.

Nickel Plating on Bumpers, Wheels and Grilles

Electroless nickel can also be used on the bumpers, wheels and grilles of a car. The use of nickel plating on parts such as these is partly due to the fact that it looks good with its shine and bright finish. But nickel also provides excellent corrosion resistance, durability and wear resistance, as is often demanded by makers of vehicles.

Nickel plating is the perfect solution to creating hard wearing, corrosion resistant brake calipers as a nickel coating is a very effective way of coating and protecting steel.

Top 5 Properties of Electroless Nickel Coatings

No other metal coating has the combination of properties offered by electroless nickel, which is why it is such a popular coating for a number of industries. As specialists in the process, we’ve put together the top 5 properties of electroless nickel plating.

Uniform Thickness

nickel plating technical figureElectroless nickel coatings can be applied in a variety of coating thicknesses. Electroless nickel can be deposited uniformly, with minimum variation from point to point. Regardless of the size and shape of the part, including recesses, holes, and complex dimensions, the uniformity of the coating can still be maintained. The range of thicknesses for electroless nickel coatings in commercial applications is 0.1 to 5 mils, however deposits as thick as 40 mils can be achieved.

Corrosion Resistance

One of the main reasons why electroless nickel plating is such a popular coating is the fact that it provides incredible corrosion resistance and corrosion protection. This property makes components coated with electroless nickel commonplace in functional applications. It is able to effectively withstand the combination of abrasion and corrosive chemicals, even in the most corrosive environments such as those encountered in drilling and producing oil wells.

Density

The density of electroless nickel coatings decline with increasing phosphorous content. That means that the higher the phosphorous content, the lower the density of the electroless nickel coating.

Adhesion

The surface preparation and activation of the electroless nickel plating is one of the most important factors for producing excellent adhesion. Electroless nickel deposits provide excellent adhesion to other substrates, for example steel, aluminium, copper and copper alloys. 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 can occur between the atoms of the coating and the substrate.

Hardness

The hardness of electroless nickel coatings depends on the phosphorus content, and can be increased by heat treatment which will in turn increase wear resistance. Generally, low phosphorous electroless nickel coatings have a high hardness of 700-750 VPN and medium phosphorus electroless nickel has a hardness of 500-550 VPN. High phosphorous coatings are not usually heat-treated, but left as-plated for their superior corrosion protection.

Top 5 Industries Using Electroless Nickel Plating

offshore oilrigElectroless nickel is an incredibly useful plating technique. Its advantages include corrosion resistance, uniformity of coating, and wear resistance, which are desirable attributes to a number of industries and applications. Here at NiTEC, we’ve put together a selection of the top 5 industries using electroless nickel plating as a coating, including application examples.

The Oil and Gas Industry

Components used in the oil and gas industry, especially those that are exposed to off shore environments, demand a very high level of protection and corrosion resistance. Electroless nickel plated components for pipelines and valves within this field have been used successfully for years. Electroless nickel plating on steel has excellent resistance in marine environments.

Engineering

Electroless nickel deposits are great for protecting components made of steel, aluminium, brass and alloys from abrasive and corrosive wear. As long as the plating solution can circulate freely in order to come into contact with all surfaces, it’s possible to achieve a specified thickness and even coating on the even the most complicated shaped components.

The Automotive Industry

Applications for electroless nickel plating are in abundance within the automotive industry due to electroless nickel plating’s good corrosion and abrasion resistance. For example, the plates of a viscous clutch can be coated, the parts for ABS systems can be nickel plated, as well as fuel injection pumps and carburettors.

The Textile Industry

Electroless nickel plated components are frequently used in the textile industry. Electroless nickel plating is very hard and has a high level of abrasion resistance. Therefore, heat treated deposits of electroless nickel and the use of composite coatings are perfect for extending the working life of parts that are in contact with fast moving textile products.

The Chemical Industry

Electroless nickel coatings are suitable for many applications in the chemical industry. This is because the coating is resistant to a wide variety of chemicals. It is often possible to use electroless nickel plating as a substitute for stainless steel. For example, it can be used for stirrers, valves, reaction tanks and covers.

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.

Nickel PTFE Self Lubricating Corrosion Resistant Coating

Nickel PTFE has natural self lubricating properties, which eliminate the need for liquid lubricants on components. The coating is not only slippery; it also has low sliding wear.

Nickel PTFE – Lubricity and Wear Resistance

Lubricity plays an important part in optimising wear resistance because it inhibits contact between the mating surfaces, reducing friction between them and therefore reducing heat which may be generated.

This self lubrication reduces the wear of nickel plated components through friction, therefore creating minimal coating weight loss. Due to nickel’s self lubrication, friction between parts is significantly reduced.

We have customers in the automotive, aerospace and oil and gas industries that all use Nickel PTFE as their choice of durable, dry lubrication and anti-galling coating.

Reduce friction between components

Reduced friction between nickel plated components reduces heat generation and reduces the formation of wear particles. Reduced friction also improves efficiency.

Protect against wear with dry lubrication

The self lubricating properties of a nickel PTFE coating also prevents wear because the moving parts are kept apart.

What can nickel PTFE be used on?

  • Valve seats and pump bearings
  • Connectors
  • Fasteners
  • Circuit breakers
  • Mould tools
  • Machine tools
  • Spindles
  • Clutches and splines
  • Cylinder liners
  • Medical moulds

If you are looking for a nickel coating that is self lubricating, corrosion resistant and wear resistant, Ni-PTFE 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.
