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.

Types of Electroless Nickel Plating and the Different Benefits of Each

As experts in the process of electroless nickel plating, we offer a range of metal plating services which all have different properties. Here’s a guide to our main services, including the benefits of each.

Low Phosphorus Electroless Nickel Plating

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.

Medium Phosphorus Electroless Nickel Plating

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.

High Phosphorus Electroless Nickel Plating

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.

Nickel PTFE Plating

Nickel PTFE plating is a unique plating solution that combines the hardness of electroless nickel with the lubricity of Polytetrafluoreothylene (PTFE). Its properties of low friction wear and self lubrication make it an excellent choice for sliding wear applications, and instances where conventional lubricants would be harmful to components.

Nickel Boron Plating

Nickel boron is a surface deposit coating that can be applied to a wide range of metals including steel, stainless steel, nickel alloys, aluminium, cobalt alloys, copper alloys, and titanium. It is a great alternative to chrome plating and has many benefits, including excellent wear and corrosion resistance. It is also resistant to fretting and galling, resistant to abrasion, ductile, solderable and has excellent rigidity.

Nickel Diamond Plating

The features of nickel diamond plating enable it to provide a highly corrosion and wear resistant coating. Due to the electroless chemical method of deposition, nickel diamond plating is able to cover surfaces with perfect uniformity. Therefore, regardless of the geometry of the component, the nickel diamond coating creates a uniform deposition on all areas of the part, even on recesses and holes. Nickel diamond plating has many other benefits which make it a superior choice of coating, including hardness and increased thermal transfer.

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.

Electroless Nickel and PTFE Composite Coating

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.
