Example of Electroless Nickel on Steel

Electroless Nickel-Teflon® Plating

Engineering properties of nickel...lubricity of teflon®...repeatable coating of uniform thickness

Electroless nickel-Teflon® is a nickel-phosphorous-polytetrafluoroethylene (PTFE) co-deposit on metal substrates. The process yields a surface with the engineering properties of nickel and the additional lubricity of Teflon®. As with standard electroless nickel, the deposit occurs via an autocatalytic chemical reaction so that a reliable, repeatable coating  of uniform thickness is generated. This makes it possible to effectively coat parts with sharp edges, deep recesses, seams, threads, and complex geometries. In some cases, the use of the electroless nickel/Teflon® provides lubricity sufficient to eliminate the use of other lubricants.

Chem Processing's electroless nickel/Teflon® coating can withstand temperatures up to 500ºF.

The appearance of the plated finish is usually dull silver-gray, and can be used as a non-reflective coating for military applications. Electroless nickel/Teflon® can be applied over a variety of substrates including stainless steel, aluminum, copper, brass and others. This process is difficult to perform well, but Chem Processing, Inc. draws on over three decades of experience to provide a consistent, high-quality finish.

This process conforms to AMS 2454.
