brake caliper nickel plating

As experts in corrosion resistant coatings, NiTEC UK have developed a range of metal plating techniques and finishes that enhance the performance and aesthetics of parts used in the automotive industry.

Our advanced metal coatings have lead to us being trusted by worldwide automotive manufacturers, and we regularly plate components used by leading makers of cars.

Increase the Corrosion Resistance of Brake Calipers with Electroless Nickel Plating

As experts in the process of electroless nickel plating, NiTEC UK regularly plate arguably the most important part of a cars’ brake part; the brake calipers. High performance brake calipers are a key part of a modern car, and nickel is excellent for protecting steel, so is the perfect coating for applications of this sort.

As brake calipers are a necessity to allow your vehicle to stop, it is essential for them to be hard wearing and long lasting. Brake calipers are a vital part of your vehicle’s breaking system as they squeeze the brake pads against the surface of the brake rotor to slow or stop the vehicle.

Most cars on the road today have disk brakes. In a disc-braking system the car’s wheels are attached to metal discs, or rotors, that spin along with the wheels. The job of the brake calipers is to slow down the wheels of the car by creating friction with the rotors. It 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.

Anti-Corrosion Coatings for High Performance Brake Calipers

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

Brake calipers are also exposed to difficult environments, for example heat, cold, summer, winter, snow and salt. Therefore, a corrosion resistant coating on these parts is very important to ensure the longevity of the cars braking system.

The History of Electroless Nickel Plating

The process of plating metal, including nickel plating, has been used to strengthen metal against corrosion and wear for hundreds of years. It has also been used to enhance the appearance of metal, which otherwise may be quite dull and not so pleasing on the eye. There are various methods of plating that have been used over the years, and still are today, including electric and chemical methods of dispersing the layer of metal coating onto a substrate.

An Historical Overview of Electroless Nickel Plating

The electroless nickel plating of metallic nickel from an aqueous solution in the presence of hypophosphite first occurred as a chemical accident by Wurtz in 1844. Progress in the field of electroless nickel plating didn’t progress much until after World War Two, when in 1946, Brenner and Riddell developed a process for plating the inner walls of tubes with nickel-tungsten alloy, which was derived from the citrate based bath using an insoluble anode, bringing out the unusual reducing properties of hypophosphite.

An Alternative Process to Conventional Electroplating

early electro platingDuring the 1954-59 period, Gutzeit at GATC (General American Transportation Corporation) worked on full scale development of electroless plating by chemical reduction alone, as an alternate process to conventional electroplating.

A study was then conducted in 1966, in which the co-deposition of particles was carried out for electrodepositing Ni-Cr by Odekerken. The study revealed that an intermediate layer consisting of finely powdered particles such as aluminium oxide and polyvinyl chloride (PVC) resin were distributed within a metallic matrix.

This meant that a layer in the electroless coating was composite, but that other parts of it were not. The first commercial application of their work occurred in 1981, when they used the electroless Ni-SiC coatings on the wankel internal combustion engine and another commercial composite incorporating polytetrafluoroethylene (Ni-P-PTFE).

The Co-Deposition of Diamond and PTFE Particles in Electroless Nickel Plating

The co-deposition of diamond and PTFE particles was proven to be more difficult, and The feasibility to incorporate the fine second phase particles, in submicron to nano size, within a metal/alloy matrix has initiated a new generation of composite coatings.

Composite Coatings of Electroless Nickel

Here at NiTEC UK, we provide a number of electroless nickel composite coatings including nickel diamond plating, nickel PTFE and nickel boron.

Beat Friction and Wear with Slippery Nickel PTFE

The problems of friction and wear on metal components can inhibit their efficiency and reduce their lifespan. Conventional lubricants can be harmful to some components, so unfortunately they are not always an option. However, the composite coating of electroless nickel PTFE can solve this problem, as the coating is actually slicker than the best self lubricating materials!

Durable Dry Lubrication with Anti-galling Requirements

nickel ptfe plated componentNi-PTFE has fantastic qualities of low friction wear and self lubrication, which make it the perfect choice for sliding wear applications where friction and wear on parts can be a problem.

The hardness of electroless nickel coupled with the low friction release properties of PTFE make it an ideal composite coating for components and assemblies where conventional lubricants are a problem.

The coating of electroless nickel PTFE is created by adding sub micron particles of PTFE to the plating solution, which are then co-deposited with the electroless nickel. This method ensures that an even distribution of the PTFE particles are deposited throughout the plated layer, and can be varied in the solution to give the performance characteristics required depending on what the final plated component will be used for.

Applications of Electroless Nickel PTFE

Electroless nickel PTFE can be used for a wide variety of applications in a range of industries. The coating is often used in the automotive industry, for example, where components including piston rings, valves, injection nozzles, carburetors, and oil pumps benefit from it. When treated with electroless nickel PTFE coatings, these parts contribute to increased fuel management for vehicles, and also demonstrate corrosion resistance, wear resistance, and tribological properties.

Electroless nickel PTFE is often used to coat pistons in the hydraulics industry, as its properties of corrosion and wear resistance are incredibly useful. It is also commonly used in the aerospace industry to coat connectors, again, improving their corrosion resistance and wear properties. When coated with electroless nickel PTFE, cutting tools and guides used in the textile industry show reduced noise and a longer lifespan.

Friction Free, Self Lubricating Electroless Nickel PTFE Coatings

nickel ptfe plated component

The PTFE composite coating of electroless nickel is known for its self lubricating properties and exceptional resistance to friction.

By combining the high wear resistant hardness, uniform coating and excellent adhesion of electroless nickel with the self lubricating properties of PTFE, it is a perfect surface treatment for components and assemblies that cannot use conventional lubricants.

Prevent Calcium Scale Build Up with PTFE

PTFE plating provides a great release from calcium that is often found in hard water areas. In addition to the corrosion resistance of the plated layer, the common problems of the build up of scale on a component can be avoided. This is especially useful when an electroless nickel PTFE coating is used on food processing equipment, heating elements and spray nozzles, as it prevents the build up of this calcium deposit which could hinder the effectiveness of the equipment.

The Process of Electroless Nickel PTFE Plating

During the process of electroless nickel PTFE plating, a coating is applied that consists of an autocatalytically applied nickel/phosphorus matrix containing submicronic particles of polytetraflouroethylene. PTFE is actually fairly soft in its natural form, but when suspended in nickel, it is very durable.

This means that components with PTFE coatings are hard enough to resist corrosion and abrasion, and also have friction resistance from the PTFE, which ensures that parts have a long working life. This coating also has the benefit of producing a uniform coating which covers all surfaces of the part, even those with especially intricate geometries.

Key Properties for Electroless Nickel PTFE

  • Low Friction
  • Self Lubrication
  • Corrosion Resistance
  • Wear Resistance
  • Uniform Deposit

Typical Applications Electroless Nickel PTFE

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

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.
