Purpose

This specification covers the requirements for electroless nickel plate that is codeposited with polytetrafluoroethylene (PTFE) over other materials.

Application

This deposit has been used typically to provide a uniform build-up on intricate shapes for improvement of wear resistance, low reflectivity, and/or as an electrically conductive finish with improved corrosion resistance, but usage is not limited to such applications. The deposit is generally dark and nonreflective. The deposit has been used in service up to 500 °F (260 °C) although wear and/or corrosion resistance may degrade as service temperature increases.

Corrosion resistance is a function of substrate material and the type and thickness of underplate and the electroless nickel PTFE composite surface layer. See 8.16.

This plating is not specifically intended for applications requiring premium solderability or adhesive bondability. See 8.15.

Application of electroless nickel PTFE composite plating to steel parts having a hardness of 46 HRC (ultimate tensile strength of 220 ksi (1517 MPa) or higher) shall not be performed unless authorized by the design documentation or specific approval has been received from the cognizant engineering organization.
