Slippery Nickel: Electroless Nickel PTFE Plating

Electroless 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.

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

Ni-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.

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?
