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.
