Chemical nickel PTFE dispersion coatings are special coatings that are applied to metallic substrates using a chemical deposition process and offer a unique combination of the properties of nickel and PTFE (polytetrafluoroethylene). These coatings are characterised by outstanding wear resistance and excellent corrosion resistance, while at the same time offering extremely low friction properties due to the embedded PTFE particles. The electroless nickel provides a hard, dense and uniform layer that protects the substrate from mechanical abrasion and chemical attack, while the PTFE particles in the nickel matrix create a self-lubricating surface that is ideal for applications where lubricity and friction reduction are critical.

The uniform deposition of the layer is independent of the geometry of the workpiece, which enables a consistent coating thickness even on complex surfaces and hard-to-reach areas. This makes electroless nickel PTFE dispersion coatings particularly suitable for precision components in the automotive, aerospace, mechanical engineering, food and medical technology industries, where the requirements for wear protection, corrosion resistance and low friction are particularly high.

Another advantage of this coating is its good adhesion to various metallic substrates, including steel, aluminium and copper alloys. These coatings are ideal for use in plain bearings, valves, pump parts, guides and other moving components that require long life and minimal maintenance. They also offer uniform coating thickness and excellent dimensional stability, minimising rework and increasing manufacturing efficiency.

Chemical nickel PTFE dispersion coatings are an innovative solution that extends the service life of components, reduces friction and improves the efficiency of machinery and equipment.
