Slippery Nickel: Electroless Nickel PTFE Plating

connector nickel teflonElectroless nickel PTFE, otherwise known as slippery nickel, is a composite nickel/PTFE coating that offers a huge range of benefits to a variety of industries. The main reason that nickel PTFE is so popular is due to its properties of low friction and self lubrication, making it a great choice for sliding wear applications and other instances where conventional lubricants cannot be used.

The Co-Deposition of Electroless Nickel PTFE

During the co-deposition process of nickel PTFE, Teflon particles are plated along with the electroless nickel and become part of the plated coating itself. This technique ensures that the plated coating has high lubricity throughout the life of the plated part, because as the coating wears, PTFE particles are exposed continuously. That means that the Teflon particles are present throughout the entire thickness of the coating.

Release Properties and Uniform Coverage

Nickel PTFE improves the “release” or anti stick properties of molds and dies due to its self lubricating properties. It also increases the efficiency of, and reduces the sound made by slides, bearings and cylinder or piston assemblies. This property also facilitates the reliable operation of moving parts when they are continuously exposed to solvents or are working in cryogenic temperatures. Nickel PTFE provides an exceptionally uniform coverage, including corners, threads and bores. There’s also no need for post-plating finishing.

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.

Composite Coatings of Electroless Nickel Plating

The chemical makeup of electroless nickel can be specially tailored to obtain the maximum coating performance for the requirements of particular applications. Composite electroless nickels incorporate distinct properties into the deposit in order to impart a specific property onto the component, and are used in a variety of industries. Here at NiTEC UK, we provide a number of electroless nickel composite coatings including nickel diamond plating, nickel PTFE and nickel boron.

A Ni-PTFE composite coating combines the properties of electroless nickel with Polytetrafluoreothylene (PTFE). Electroless nickel coatings are typically very hard, and PTFE is good for its lubricity, therefore combining the two produces a very useful coating for several industries including automotive, machinery, and engineering. Nickel PTFE has properties of low friction wear and self lubrication which make it an excellent choice for sliding wear applications, and instances where conventional lubricants would be harmful to components.

Nickel Boron Composite Coating

Electroless nickel can also be combined with boron as an alternative to chrome plating, producing a coating that is excellent wear and corrosion resistance properties. A composite coating of electroless nickel and boron will reduce the drag and friction of surfaces that slide up against each other. Also, its nodular surface allows it to dissipate heat efficiently.

Nickel Diamond Composite Coating

As the name suggests, nickel diamond coatings combine an electroless nickel deposit with fine particles of diamond. Using diamond particles in this way is a really cost effective method of utilising the benefits of diamond on the surface of a component, providing a highly corrosion and wear resistant coating.

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
