PEN-TUF®/EN (Co-Deposited Electroless Nickel with PTFE) or Electroless Nickel Plating with PTFE
PEN-TUF®/EN is an Electroless Nickel Composite coating containing particles of PTFE evenly dispersed in a Nickel Phosphorus matrix. During the plating process the PTFE particles are suspended in the Electroless Nickel bath creating a uniform co-deposit.
By combining the lubricity of PTFE with many features of Electroless Nickel, PEN-TUF®/EN is able to meet a broad range of engineering applications. PTFE is one of the most lubricious materials available and when co-deposited with Electroless Nickel it provides a superior wear coating with a coefficient of friction around 0.1. The Electroless nickel content of our PEN-TUF®/EN coatings ensures uniform coating thickness, corrosion resistance, and durability. Typical thicknesses of the coating range between .0001-.0004”. If a thicker coating is required an undercoat of Electroless Nickel can be applied.
